Offered options include speeds down to 5ns and a 100μA pin-controlled power-down mode. All speed ranges are specified over the full 5V ± 10% range for industrial temperature ranges, and 5V ± 5% for commercial range 5V devices. The ATF16V8C incorporates a superset of the generic architectures, which allows direct replacement of the 16R8 family and most 20-pin combinatorial PLDs. Eight outputs are each allocated eight product terms. Three different modes of operation are configured auto- matically with software, and allow highly complex logic functions to be realized. The ATF16V8C can significantly reduce total system power, thereby enhancing system reli- ability and reducing power supply costs. When pin 4 is configured as the power-down control pin, supply current drops to less than 100μA whenever the pin is high. If the power- down feature isn't required for a particular application, pin 4 may be used as a logic input. Also, the pin-keeper circuits eliminate the need for internal pull-up resistors along with their attendant power consumption. 0425H–PLD–3/11

7. Power-up reset Registers of the ATF16V8C are designed to reset during power-up. At a point delayed slightly from V crossing V , all CC RST registers will be reset to the low state. As a result, the registered output state will always be high on power-up. This feature is critical for state machine initialization. However,due to the asynchronous nature of reset and the uncertainty of how V actually rises in the system, the followingconditions are required: CC 1. The V rise must be monotonic, from below 0.7V CC 2. After reset occurs, all input and feedback setup times must be met before driving the clock term high, and 3. The signals from which the clock is derived must remain stable during t PR Figure 8. Power-up reset Table 8-1. Power-up reset parameters Parameter Description Typ Max Units t Power-up PR 600 1,000 ns Reset Time V Power-up RST 3.8 4.5 V Reset Voltage 9. Power-down mode The ATF16V8C includes an optional pin controlled powerdown feature. Device pin 4 may be configured as the power- down pin. When this feature is enabled and the power-down pin is high, total current consumption drops to less than 100μA. In the power-down mode, all output data and internal logic states are latched and held. All registered and combinatorial output data remains valid. Any outputs that were in a high-Z state at the onset of power-down will remain at high-Z. During power-down, all input signals except the power-down pin are blocked. The input and I/O pin-keeper circuits remain active to insure that pins do not float to indeterminate levels. This helps to further reduce system power. Selection of the power-down option is specified in the ATF16V8C logic design file. The logic compiler will include this option selection in the otherwise standard 16V8 JEDEC fuse file. When the power-down feature is not specified in the design file, pin 4 is available as a logic input, and there is no power-down pin. This allows the ATF16V8C to be programmed using any existing standard 16V8 fuse file. Note: Some programmers list the JEDEC-compatible 16V8C (No PD used) separately from the non-JEDEC compatible 16V8CEXT. (EXT for extended features.) 10. Registered output preload Registers of the ATF16V8C are provided with circuitry to allow loading of each register with either a high or a low. This feature will simplify testing since any state can be forced into the registers to control test sequencing. A JEDEC file with preload is generated when a source file with vectors is compiled. Once downloaded, the JEDEC file preload sequence will be done automatically by approved programmers. Atmel ATF16V8C 6 0425H–PLD–3/11

Atmel ATF16V8C 11. Security fuse usage A single fuse is provided to prevent unauthorized copying of the ATF16V8C fuse patterns. Once programmed, fuse verify and preload are inhibited. However, the 64-bit user signature remains accessible. The security fuse will be programmed last, as its effect is immediate. 12. Input and I/O pin-keeper circuits The ATF16V8C contains internal input and I/O pin-keeper circuits. These circuits allow each ATF16V8C pin to hold its previous value even when it is not being driven by an externalsource or by the device’s output buffer. This helps insure that all logic array inputs are at known, valid logic levels. This reduces system power by preventing pins from floating to indeterminate levels. By using pin-keeper circuits rather than pull-up resistors, there is no DC current required to hold the pins in either logic state (high or low). These pin-keeper circuits are implemented as weak feedback inverters, as shown in the Input Diagram below. These keeper circuits can easily be overdriven by standard TTL- or CMOS-compatible drivers. The typical overdrive current required is 40μA. Figure 13. Input diagram Figure 14. I/O diagram 7 0425H–PLD–3/11

15. Functional logic diagram description The logic option and functional diagrams describe the ATF16V8C architecture. Eight configurable macrocells can be configured as a registered output, combinatorial I/O, combinatorial output, or dedicated input. The ATF16V8C can be configured in one of three different modes. Each mode makes the ATF16V8C look like a different device. Most PLD compilers can choose the right mode automatically. The user can also force the selection by supplying the compiler with a mode selection. The determining factors would be the usage of register versus combinatorial outputs and dedicated outputs versus outputs with output enable control. The ATF16V8C universal architecture can be programmed to emulate many 20-pin PAL devices. These architectural subsets can be found in each of the configuration modes described in the following pages. The user can download the listed subset device JEDEC programming file to the PLD programmer, and the ATF16V8C can be configured to act like the chosen device. Check with your programmer manufacturer for this capability. Unused product terms are automatically disabled by the compiler to decrease power consumption. A security fuse, when programmed, protects the content of the ATF16V8C. Eight bytes (64 fuses) of user signature are accessible to the user for purposes such as storing project name, part number, revision, or date. The user signature is accessible regardless of the state of the security fuse. Table 15-1.

Macrocell configuration Software compilers support the three different OMC modes as different device types. These device types are listed in the table below. Most compilers have the ability to automatically select the device type, generally based on the register usage and output enable (OE) usage. Register usage on the device forces the software to choose the registered mode. All combinatorial outputs with OE controlled by the product term will force the software to choose the complex mode. The software will choose the simple mode only when all outputs are dedicated combinatorial without OE control. The different device types listed in the table can be used to override the automatic device selection by the software. For further details, refer to the compiler software manuals. When using compiler software to configure the device, the user must pay special attention to the following restrictions in each mode. In registered mode, pin 1 and pin 11 are permanently configured as clock and output enable, respectively. These pins cannot be configured as dedicated inputs in the registered mode. In complex mode, pin 1 and pin 11 become dedicated inputs and use the feedback paths of pin 19 and pin 12 respectively. Because of this feedback path usage, pin 19 and pin 12 do not have the feedback option in this mode. Atmel ATF16V8C 8 0425H–PLD–3/11

Atmel ATF16V8C In simple mode, all feedback paths of the output pins are routed via the adjacent pins. In doing so, the two inner most pins (pins 15 and 16) will not have the feedback option as these pins are always configured as dedicated combinatorial output. 16.1 Atmel ATF16V8C registered mode PAL device emulation/PAL replacement. The registered mode is used if one or more registers are required. Each macrocell can be configured as either a registered or combinatorial output or I/O, or as an input. For a registered output or I/O, the output is enabled by the OE pin, and the register is clocked by the CLK pin. Eight productterms are allocated to the sum term. For a combinatorial output or I/O, the output enable is controlled by a product term, and seven product terms are allocated to the sum term. When the macrocell is configured as an input, the output enable is permanently disabled. Any register usage will make the compiler select this mode. The following registered devices can be emulated using this mode: 16R8 16RP8 16R6 16RP6 16R4 16RP4 Figure 17. Registered configuration for registered mode(1)(2) Notes: 1. Pin 1 controls common CLK for the registered outputs. Pin 11 controls common OE for the registered outputs. Pin 1 and Pin 11 are permanently configured as CLKand OE. 2. The development software configures all the architecture control bits and checks for proper pin usage automatically. Figure 18. Combinatorial configuration for registered mode(1)(2) Notes: 1. Pin 1 and Pin 11 are permanently configured as CLK and OE. 2. The development software configures all the architecture control bits and checks for proper pin usage automatically. 9 0425H–PLD–3/11

Atmel ATF16V8C 20. Atmel ATF16V8C complex mode PAL device emulation/PAL replacement. In the complex mode, combinatorial output and I/O functions are possible. Pins 1 and 11 are regular inputs to the array. Pins 13 through 18 have pin feedback paths back to the AND-array, which makes full I/O capability possible. Pins 12 and 19 (outermost macrocells) are outputs only. They do not have input capability. In this mode, each macrocellhas seven product terms going to the sum term and one product term enabling the output. Combinatorial applications with an OE requirement will make the compiler select this mode. The following devices can be emulated using this mode: 16L8 16H8 16P8 Figure 21. Complex Mode Option 22. Atmel ATF16V8C simple mode PAL device emulation/PAL replacement. In the simple mode, eight product terms are allocated to the sum term. Pins 15 and 16 (center macrocells) are permanently configured as combinatorial outputs. Other macrocells can be either inputs or combinatorial outputs with pin feedback to the AND-array. Pins 1 and 11 are regular inputs. The compiler selects this mode when all outputs are combinatorial without OE control. The following simple PALs can be emulated using this mode: 10L8 10H8 10P8 12L6 12H6 12P6 14L4 14H4 14P4 16L2 16H2 16P2 Figure 23. Simple mode option 0 1 11 0425H–PLD–3/11
