SX-A Family FPGAs General Description Introduction SX-A Family Architecture The Actel SX-A family of FPGAs offers a cost-effective, The SX-A family’s device architecture provides a unique single-chip solution for low-power, high-performance approach to module organization and chip routing that designs. Fabricated on 0.22 μm / 0.25 μm CMOS satisfies performance requirements and delivers the most antifuse technology and with the support of 2.5 V, optimal register/logic mix for a wide variety of 3.3 V and 5 V I/Os, the SX-A is a versatile platform to applications. integrate designs while significantly reducing time- Interconnection between these logic modules is achieved to-market. using Actel’s patented metal-to-metal programmable antifuse interconnect elements (Figure1-1). The antifuses are normally open circuit and, when programmed, form a permanent low-impedance connection. Routing Tracks Amorphous Silicon/ Dielectric Antifuse Tungsten Plug Via Metal 4 Metal 3 Tungsten Plug Via Metal 2 Metal 1 Tungsten Plug Contact Silicon Substrate Note: The A54SX72A device has four layers of metal with the antifuse between Metal 3 and Metal 4. The A54SX08A, A54SX16A, and A54SX32A devices have three layers of metal with the antifuse between Metal 2 and Metal 3. Figure 1-1 (cid:129) SX-A Family Interconnect Elements v5.3 1-1

SX-A Family FPGAs Logic Module Design different combinatorial functions to be implemented in a single module. An example of the flexibility enabled by The SX-A family architecture is described as a “sea-of- the inversion capability is the ability to integrate a 3-input modules” architecture because the entire floor of the exclusive-OR function into a single C-cell. This facilitates device is covered with a grid of logic modules with construction of 9-bit parity-tree functions with 1.9 ns virtually no chip area lost to interconnect elements or propagation delays. routing. The Actel SX-A family provides two types of logic modules: the register cell (R-cell) and the Module Organization combinatorial cell (C-cell). The R-cell contains a flip-flop featuring asynchronous clear, All C-cell and R-cell logic modules are arranged into asynchronous preset, and clock enable, using the S0 and S1 horizontal banks called Clusters. There are two types of lines control signals (Figure1-2). The R-cell registers feature Clusters: Type 1 contains two C-cells and one R-cell, while programmable clock polarity selectable on a register-by- Type 2 contains one C-cell and two R-cells. register basis. This provides additional flexibility while Clusters are grouped together into SuperClusters allowing mapping of synthesized functions into the SX-A (Figure1-4 on page 1-3). SuperCluster 1 is a two-wide FPGA. The clock source for the R-cell can be chosen from grouping of Type 1 Clusters. SuperCluster 2 is a two-wide either the hardwired clock, the routed clocks, or internal group containing one Type 1 Cluster and one Type 2 Cluster. SX-A devices feature more SuperCluster 1 logic. modules than SuperCluster 2 modules because designers The C-cell implements a range of combinatorial functions typically require significantly more combinatorial logic of up to five inputs (Figure1-3).

SX-A Family FPGAs Routing Resources The routing and interconnect resources of SX-A devices interconnection to achieve its fast signal propagation are in the top two metal layers above the logic modules time of less than 0.1 ns. (Figure1-1 on page 1-1), providing optimal use of silicon, FastConnect enables horizontal routing between any thus enabling the entire floor of the device to be two logic modules within a given SuperCluster, and spanned with an uninterrupted grid of logic modules. vertical routing with the SuperCluster immediately Interconnection between these logic modules is achieved below it. Only one programmable connection is used in a using the Actel patented metal-to-metal programmable FastConnect path, delivering a maximum pin-to-pin propagation time of 0.3 ns. antifuse interconnect elements. The antifuses are normally open circuits and, when programmed, form a In addition to DirectConnect and FastConnect, the permanent low-impedance connection. architecture makes use of two globally oriented routing resources known as segmented routing and high-drive Clusters and SuperClusters can be connected through the routing. The Actel segmented routing structure provides use of two innovative local routing resources called a variety of track lengths for extremely fast routing FastConnect and DirectConnect, which enable extremely between SuperClusters. The exact combination of track fast and predictable interconnection of modules within lengths and antifuses within each path is chosen by the Clusters and SuperClusters (Figure1-5 on page 1-4 and 100% automatic place-and-route software to minimize Figure1-6 on page 1-4). This routing architecture also signal propagation delays. dramatically reduces the number of antifuses required to The general system of routing tracks allows any logic complete a circuit, ensuring the highest possible module in the array to be connected to any other logic performance, which is often required in applications such or I/O module. Within this system, most connections as fast counters, state machines, and data path logic.

Since adherence to the maximum slew rate was not required prior to revision 2.1 of the specification, there may be components in the market for some time that have faster edge rates; therefore, motherboard designers must bear in mind that rise and fall times faster than this specification could occur and should ensure that signal integrity modeling accounts for this.

SX-A Family FPGAs Power Dissipation A critical element of system reliability is the ability of electronic devices to safely dissipate the heat generated during operation. The thermal characteristics of a circuit depend on the device and package used, the operating temperature, the operating current, and the system's ability to dissipate heat. A complete power evaluation should be performed early in the design process to help identify potential heat-related problems in the system and to prevent the system from exceeding the device’s maximum allowed junction temperature. The actual power dissipated by most applications is significantly lower than the power the package can dissipate. However, a thermal analysis should be performed for all projects. To perform a power evaluation, follow these steps: 1. Estimate the power consumption of the application. 2. Calculate the maximum power allowed for the device and package. 3. Compare the estimated power and maximum power values. Estimating Power Dissipation The total power dissipation for the SX-A family is the sum of the DC power dissipation and the AC power dissipation: P = P + P Total DC AC EQ 2-5 DC Power Dissipation The power due to standby current is typically a small component of the overall power. An estimation of DC power dissipation under typical conditions is given by: P = I * V DC Standby CCA EQ 2-6 Note: For other combinations of temperature and voltage settings, refer to the eX, SX-A and RT54SX-S Power Calculator. AC Power Dissipation The power dissipation of the SX-A family is usually dominated by the dynamic power dissipation. Dynamic power dissipation is a function of frequency, equivalent capacitance, and power supply voltage. The AC power dissipation is defined as follows: P =P + P + P + P + P + P + P AC C-cells R-cells CLKA CLKB HCLK OutputBuffer InputBuffer EQ 2-7 or: PAC = VCCA2 * [(m * CEQCM * fm)C-cells + (m * CEQSM * fm)R-cells + (n * CEQI * fn)InputBuffer + (p * (CEQO + CL) * fp)OutputBuffer + (0.5 * (q * C * f ) + (r * f )) + (0.5 * (q * C * f )+ (r * f )) + (0.5 * (s * C * f ) + 1 EQCR q1 1 q1 CLKA 2 EQCR q2 2 q2 CLKB 1 EQHV s1 (C * f )) ] EQHF s1 HCLK EQ 2-8 2-8 v5.3

SX-A Family FPGAs Thermal Characteristics Introduction The temperature variable in Actel Designer software refers to the junction temperature, not the ambient, case, or board temperatures. This is an important distinction because dynamic and static power consumption will cause the chip's junction to be higher than the ambient, case, or board temperatures. EQ2-9 and EQ2-10 give the relationship between thermal resistance, temperature gradient and power.

SX-A Family FPGAs Theta-JA Junction-to-ambient thermal resistance (θ ) is determined under standard conditions specified by JESD-51 series but JA has little relevance in actual performance of the product in real application. It should be employed with caution but is useful for comparing the thermal performance of one package to another. A sample calculation to estimate the absolute maximum power dissipation allowed (worst case) for a 329-pin PBGA package at still air is as follows. i.e.: θ = 17.1°C/W is taken from Table2-12 on page2-11 JA T = 125°C is the maximum limit of ambient (from the datasheet) A Max Junction Temp–Max. Ambient Temp 150°C–125°C Max. Allowed Power = ------------------------------------------------------------------------------------------------------------ = ---------------------------------------- = 1.46 W θ 17.1°C/W JA EQ 2-11 The device's power consumption must be lower than the calculated maximum power dissipation by the package. The power consumption of a device can be calculated using the Actel power calculator. If the power consumption is higher than the device's maximum allowable power dissipation, then a heat sink can be attached on top of the case or the airflow inside the system must be increased. Theta-JC Junction-to-case thermal resistance (θ ) measures the ability of a device to dissipate heat from the surface of the chip JC to the top or bottom surface of the package. It is applicable for packages used with external heat sinks and only applies to situations where all or nearly all of the heat is dissipated through the surface in consideration. If the power consumption is higher than the calculated maximum power dissipation of the package, then a heat sink is required. Calculation for Heat Sink For example, in a design implemented in a FG484 package, the power consumption value using the power calculator is 3.00 W. The user-dependent data T and T are given as follows: J A T = 110°C J T = 70°C A From the datasheet: θ = 18.0°C/W JA θ = 3.2 °C/W JC Max Junction Temp–Max. Ambient Temp 110°C–70°C P = ------------------------------------------------------------------------------------------------------------ = ------------------------------------ = 2.22 W θ 18.0°C/W JA EQ 2-12 The 2.22 W power is less than then required 3.00 W; therefore, the design requires a heat sink or the airflow where the device is mounted should be increased. The design's junction-to-air thermal resistance requirement can be estimated by: Max Junction Temp–Max. Ambient Temp 110°C–70°C θ = ------------------------------------------------------------------------------------------------------------ = ------------------------------------ = 13.33°C/W JA P 3.00 W EQ 2-13 2-12 v5.3

SX-A Family FPGAs To determine the heat sink's thermal performance, use the following equation: θ = θ +θ +θ JA(TOTAL) JC CS SA EQ 2-14 where: θ = 0.37°C/W CS = thermal resistance of the interface material between the case and the heat sink, usually provided by the thermal interface manufacturer θ = thermal resistance of the heat sink in °C/W SA θ = θ –θ –θ SA JA(TOTAL) JC CS EQ 2-15 θ = 13.33°C/W–3.20°C/W–0.37°C/W SA θ = 9.76°C/W SA A heat sink with a thermal resistance of 9.76°C/W or better should be used. Thermal resistance of heat sinks is a function of airflow. The heat sink performance can be significantly improved with the presence of airflow. Carefully estimating thermal resistance is important in the long-term reliability of an Actel FPGA. Design engineers should always correlate the power consumption of the device with the maximum allowable power dissipation of the package selected for that device, using the provided thermal resistance data. Note: The values may vary depending on the application. v5.3 2-13

SX-A Family FPGAs Datasheet Categories In order to provide the latest information to designers, some datasheets are published before data has been fully characterized. Datasheets are designated as "Product Brief," "Advanced," "Production," and "Datasheet Supplement." The definitions of these categories are as follows: Product Brief The product brief is a summarized version of a datasheet (advanced or production) containing general product information. This brief gives an overview of specific device and family information. Advanced This datasheet version contains initial estimated information based on simulation, other products, devices, or speed grades. This information can be used as estimates, but not for production. Unmarked (production) This datasheet version contains information that is considered to be final. Datasheet Supplement The datasheet supplement gives specific device information for a derivative family that differs from the general family datasheet. The supplement is to be used in conjunction with the datasheet to obtain more detailed information and for specifications that do not differ between the two families. International Traffic in Arms Regulations (ITAR) and Export Administration Regulations (EAR) The products described in this datasheet are subject to the International Traffic in Arms Regulations (ITAR) or the Export Administration Regulations (EAR). They may require an approved export license prior to their export. An export can include a release or disclosure to a foreign national inside or outside the United States. v5.3 4-3
