Z84C9010VEG

Specialized Overview

The Z84C9010VEG is a Serial/Parallel Counter/Timer KIO peripheral manufactured by Zilog. It integrates the functionality of a Z84C30 CTC, a Z84C20 PIO, and a Z84C4x SIO into a single device. The component operates at a maximum bus clock frequency of 10 MHz and requires a single +5 V power supply. It is housed in an 84-pin PLCC package with surface mount installation. The device supports Z80 family interrupt daisy chains and includes an on-chip clock oscillator.

Specialized Feature Summary

• Integrates two independent synchronous/asynchronous serial channels for versatile communication protocols
• Includes three 8-bit parallel ports (PIO and PIA) supporting bidirectional data transfer and handshake signals
• Features four independent counter/timer channels compatible with standard CTC logic
• Contains an on-chip clock oscillator/driver accepting crystal or TTL-compatible inputs

Specialized Applications

• I/O controller interface systems
• Serial communications peripherals
• Counter and timer applications

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for Product Change Notifications (PCN). Review the official datasheet for absolute maximum ratings and handling precautions before integration.

Specialized Selection Notes

Select this model when a combined solution for serial, parallel, and timing functions is required within a Z80-based architecture. Ensure the system design accommodates the 84-pin PLCC footprint and provides the necessary 5V power supply. Verify that the 10 MHz operating speed meets the specific timing requirements of the target application.

Specialized Part Context

This part belongs to the Z84C90 KIO series, which consolidates multiple peripheral functions into one package. It is designed to work optimally with Z84C00 CPUs but remains compatible with other processors in the Z80 family. The device simplifies board layout by reducing the number of discrete components needed for I/O management.
