Z84C9010ASC00TR

Specialized Overview

The Z84C9010ASC00TR is a CMOS Serial/Parallel Counter/Timer KIO peripheral in a 100-pin LQFP package, operating at a maximum bus clock frequency of 10 MHz. It integrates two synchronous/asynchronous serial channels, three 8-bit parallel ports (PIO), four independent counter/timer channels, and an on-chip crystal oscillator. The device supports software/hardware resets, single +5 V power supply operation, and programmable interrupt priorities within the Z80 family daisy chain.

Specialized Feature Summary

• Integrates SIO, CTC, PIO, and PIA logic into a single chip
• Supports full duplex asynchronous and synchronous serial protocols
• Features bit-programmable I/O port with multiplexed modem control signals
• Includes internal command logic for configurable interrupt priority sequencing

Specialized Applications

• Multichannel I/O peripheral expansion for Z80-based systems
• Serial communication interface design requiring dual channels
• Hardware timing and event counting applications

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm datasheet revision PS011804-0612 matches the specific lot. Ensure environmental compliance documentation aligns with project requirements prior to final procurement authorization.

Specialized Selection Notes

Select this variant specifically for 10 MHz system clock requirements. Verify that the 100-pin LQFP footprint matches the PCB layout constraints. Ensure the application utilizes a single +5 V supply rail compatible with the specified DC characteristics.

Specialized Part Context

This component belongs to the Z84C90 KIO series, which combines multiple Zilog peripherals. The 'ASC' suffix indicates the 10 MHz speed grade and 100-pin LQFP packaging. It serves as a comprehensive I/O solution replacing discrete SIO, CTC, and PIO chips in legacy Z80 architectures.

Specialized Replacement Considerations

Direct functional replacements include other Z84C90 variants such as Z84C9010VSC for PLCC packages or Z84C9012VSC for higher frequency needs. Cross-package pinouts differ; verify physical compatibility before substitution.
