These bits can be used for user-specific data. 7. Programming/Erasing Programming/erasing is performed using standard PLD programmers. See CMOS PLD Pro- gramming Hardware and Software Support for information on software/programming. 8. Input and I/O Pull-ups All ATF16V8B family members have internal input and I/O pull-up resistors. Therefore, when- ever inputs or I/Os are not being driven externally, they will float to V CC. This ensures that all logic array inputs are at known states. These are relatively weak active pull-ups that can easily be overdriven by TTL-compatible drivers (see input and I/O diagrams below). Figure 8-1. Input Diagram Figure 8-2. I/O Diagram 9. Functional Logic Diagram Description The Logic Option and Functional Diagrams describe the ATF16V8B architecture. Eight config- urable macrocells can be configured as a registered output, combinatorial I/O, combinatorial output, or dedicated input. The ATF16V8B can be configured in one of three different modes. Each mode makes the ATF16V8B look like a different device. Most PLD compilers can choose the right mode automat- ically. 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 dedi- cated outputs versus outputs with output enable control. The ATF16V8B 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 |
