C8254 Programmable Timer/Counter Core

The C8254 core implements a high performance programmable interval timer/counter device, which is designed to solve the common timing control problems in microcomputer system design. It provides three independent 16-bit counters, and each counter may operate in a different mode. All modes are software programmable. The C8254 solves one of the most common problems in any microcomputer system, the generation of accurate time delays under software control programmed to match the requirements by programming one of the counters for the desired delay.

This core can be mapped to any any Intel, Lattice, MicroSemi, or Xilinx programmable device, or to any ASIC technology, provided sufficient silicon resources are available. Please contact CAST Sales to get accurate characterization data for your specific implementation requirements. Meanwhile, we provide the following representative results (each in a new pop-up window):

Applications

The six programmable timer modes allow the C8254 to be used in applications requiring event counters including:

Support

The core as delivered is warranted against defects for ninety days from purchase. Thirty days of phone and email technical support are included, starting with the first interaction. Additional maintenance and support options are available.

Verification

The C8254 core’s functionality was verified by means of a proprietary hardware modeler. The same stimulus was applied to a hardware model that contained the original Intel 82C54 chip, and the results compared with the core’s simulation output.

Deliverables

The core is available in ASIC (synthesizable HDL) and FPGA (netlist) forms, and includes everything required for successful implementation:
