APC464:
Digital I/O (TTL) and Counter/Timers
• 64 TTL digital input/output channels
• Four 16-bit or two 32-bit counter/timer channels
• Six operating modes
• TTL-compatible thresholds
The APC464 provides 64 TTL digital input/output channels and four 16-bit multi-function counter/timers.
All 64 I/O channels, when set as inputs, support configuration for interrupts on either a change-of-state or on a high-to-low or low-to-high transition. A debounce timer is selectable to help filter out false transitions.
Four 16-bit multifunction counters/timers are configurable for pulse width modulated output, watchdog timer, event counter, frequency measurement, pulse width measurement, period measurement, or one shot pulse output. The four 16-bit counters can also be configured into two 32-bit counter/timers.
