Z84C9010VEC00TR

Specialized Overview

The Z84C9010VEC00TR is a Serial/Parallel Counter/Timer KIO peripheral manufactured by Zilog. It integrates a Z84C30 CTC, Z84C20 PIO, and Z84C4x SIO with an 8-bit bit-programmable I/O port and crystal oscillator into a single package. The device operates at a bus clock frequency of 10 MHz and requires a single +5 V power supply. It utilizes fifteen internal registers for configuration and supports software/hardware resets. The component is housed in an 84-pin PLCC package.

Specialized Feature Summary

• Integrates two independent synchronous/asynchronous serial channels, three 8-bit parallel ports, and four independent counter/timer channels within a single unit.
• Features an on-chip clock oscillator/driver that accepts crystal or TTL-compatible inputs to generate MOS-compatible outputs.
• Supports Z80 Family interrupt daisy chain with programmable priority levels among the integrated peripherals.

Specialized Applications

• Multichannel I/O peripheral solutions for Z80-based systems
• Serial communications applications requiring asynchronous and synchronous protocols
• Event counting and interval timing implementations

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and speed grade. Confirm availability status directly with the manufacturer as distribution channels may vary. Ensure compatibility with the target system's voltage requirements and pinout configurations before procurement.

Specialized Selection Notes

Select this component when a consolidated solution for serial, parallel, and timer functions is required for Z80 architecture. Verify that the 10 MHz operating frequency meets system timing constraints. Ensure the design accommodates the 84-pin PLCC footprint and associated thermal management requirements.
