Z84C3008PEC

Overview

The Z84C3008PEC is a CMOS Counter/Timer Circuit (CTC) from the Zilog Z80 family, designed for I/O controller applications. It operates on a single 5V supply and supports clock frequencies up to 8 MHz. The device features three independent timer channels within a 28-pin PDIP package. It is compatible with the Z80 CPU bus architecture and includes low-power idle modes. The component is classified as obsolete.

Feature Summary

• Three independent 16-bit counter/timer channels
• Compatible with Z80 CPU bus interface
• Operates at clock frequencies up to 8 MHz
• Single 5V power supply operation

Applications

• I/O Controller Interface ICs
• System timing and event counting
• Z80-based embedded systems

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Availability is limited to surplus or secondary market sources. Verify RoHS compliance status carefully, as older batches may not meet current environmental regulations. Confirm pinout and electrical specifications against original datasheets before integration into new designs.

Selection Notes

Select this part for legacy Z80 system maintenance where specific CTC functionality is required. Ensure the design accommodates the 28-pin PDIP footprint. Consider thermal management if operating near the maximum 8 MHz frequency limit. Verify that the application does not require modern RoHS-compliant alternatives if strict environmental standards apply.

Part Context

The Z84C3008PEC belongs to the Z84C30 series of CMOS Counter/Timer Circuits. It serves as a peripheral interface chip for Z80 microprocessors, providing hardware timers and counters. It is distinct from the Z84C40 serial I/O controllers and Z84C10 microprocessors within the same product family.
