Z0843004PSC, Z80 CTC Counter/Timer, DIP-28

The Z0843004PSC (Z80 CTC) is a programmable counter/timer circuit, designed to function as an interrupt-driven counter/timer for the Z80 microprocessor family. It features four independent 8-bit counters/timers, which can be programmed for various timing applications, such as baud rate generation, event counting, and precision timing. Operating at 5V, the Z0843004PSC supports a maximum clock frequency of 4MHz, ensuring high-speed operation. It includes programmable interrupt vector generation, simplifying multi-device interrupt management. With its DIP-28 package, the Z80 CTC is ideal for embedded system design, real-time clock applications, frequency measurement, and industrial automation.
