Z84C3010VEC

Overview

The Z84C3010VEC is a CMOS Counter/Timer Circuit (CTC) manufactured by Zilog, operating at a maximum clock frequency of 10 MHz. It features an 8-bit external data bus and integrates one timer channel within a 44-pin PLCC package. The device supports the Z80 processor bus architecture and functions as a programmable timer and support product. It operates within a temperature range of -40°C to +100°C and is housed in a plastic epoxy LCC body.

Feature Summary

• CMOS technology with 10 MHz maximum clock frequency
• Integrated single-channel programmable timer
• Z80-compatible 8-bit external data bus interface
• 44-pin Plastic Leadless Chip Carrier (PLCC) surface mount package

Applications

• Programmable timing control for Z80-based systems
• Counter applications in industrial embedded controllers
• Clock generation and signal processing in microprocessor support circuits

Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and current stock levels are limited or unavailable through standard distribution channels. Verification of lifecycle status and alternative sourcing strategies is required before procurement planning.

Selection Notes

Select this part for designs requiring a dedicated hardware timer compatible with Z80 architecture. Ensure the system design accommodates the 44-pin PLCC footprint and the specific voltage requirements of the Z84C series. Verify that the 10 MHz speed meets the timing resolution needs of the application.

Part Context

The Z84C3010VEC belongs to the Z84C30 series of I/O controller interface ICs and timers. It is part of Zilog's broader portfolio of peripheral chips designed to extend the capabilities of their Z80 family microprocessors and microcontrollers.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineering change orders may be necessary to adopt pin-compatible or functionally equivalent alternatives from other manufacturers.
