Z84C3008VEC

Overview

The Z84C3008VEC is an 8-bit CMOS Central Timer Counter (CTC) peripheral designed for the Z80 processor family. Operating at a maximum clock frequency of 10 MHz, it features four independent timer/counter channels with programmable modes and interrupt capabilities. The device utilizes a 44-pin PLCC package and functions within a supply voltage range of 5 V. It supports an industrial temperature range from -40°C to +100°C, ensuring reliable performance in demanding environments.

Feature Summary

• Four independent 16-bit timer/counter channels
• Maximum operating frequency of 10 MHz
• Compatible with Z80 CPU architecture
• Industrial temperature range (-40°C to +100°C)

Applications

• Real-time clock generation
• Serial baud rate generation
• Pulse width modulation control
• Event counting applications

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance status as historical data indicates mixed certification levels across the Z84C series. Check for moisture sensitivity handling requirements prior to soldering. Validate pin compatibility with existing PCB footprints before procurement.

Selection Notes

Select this model when four dedicated hardware timers are required for Z80-based systems. Ensure the design accommodates the 44-pin PLCC footprint. Compare against the Z84C3008AEG if lower speed or different packaging is acceptable. Verify that the 10 MHz limit meets system timing requirements.

Part Context

Part of the Zilog Z84C30 series, which provides CTC functionality for Z80 microprocessors. This series complements the Z84C00 CPU and Z84C10 DMA controllers. The Z84C3008VEC represents the high-speed variant within the standard PLCC package lineup.

Replacement Considerations

The Z84C3008AEG serves as a direct functional substitute with identical specifications but potentially different packaging or certification. Cross-reference datasheets to confirm pinout and electrical parameter equivalence before substitution.
