Z84C3010VEG

Overview

The Z84C3010VEG 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 is housed in a 44-pin PLCC package. The device supports standard Z80 bus compatibility and functions as a programmable timer within the Z84C30 series. It operates within a temperature range of -40°C to +100°C and requires a 5V supply voltage.

Feature Summary

• 10 MHz CMOS Counter/Timer Circuit
• 8-bit data bus with Z80 bus compatibility
• 44-pin PLCC surface mount package
• Extended industrial temperature range (-40°C to +100°C)

Applications

• Z80-based microprocessor system timing control
• Programmable interval generation in embedded controllers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notices or production change notifications that may affect long-term availability.

Selection Notes

Select this component when a dedicated hardware timer is required for Z80 architecture systems. Ensure the design accommodates the 44-pin PLCC footprint and 5V logic levels. Compare against the Z84C3010VEC if lead-free requirements differ, though functional specifications remain consistent.

Part Context

This part belongs to the Z84C30 series of I/O controller interface ICs designed for Zilog's Z80 family processors. It serves as a peripheral chip providing precise timing and counting capabilities essential for real-time control applications in legacy and specialized industrial computing environments.

Replacement Considerations

The Z84C3010VEC is a functionally equivalent alternative within the same series. Verify pinout compatibility and package dimensions before substitution. No other direct cross-model substitutes are documented in public sources.
