Main Features
  • FPGA IP Core
  • 8254-compatible timer/counter
  • Up to 9 counters
  • Wishbone bus interface
Description Open

This counter is compatible with the 82C54 programmable Interval Timer Chip. It is recommended to read the datasheet of the 82C54 in order to fully understand the requirements and to see all the programming examples. The IP core is included into a timer counter unit, which includes clock input switching, interrupt logic and a programmable time base. The timer/counter unit provides three 8254 chips, so 9 counters can be used. Every individual part of the timer/counter unit has a Wishbone interface, so it can be used as a stand-alone module.
