Z84C9010ASG00TR

Specialized Overview

The Z84C9010ASG00TR is a Serial/Parallel Counter/Timer KIO peripheral manufactured by Zilog. It integrates a Z84C30 CTC, Z84C20 PIO, and Z84C4x SIO with an on-chip oscillator into a single package. The device supports bus clock frequencies of 8, 10, and 12.5 MHz. This specific variant operates at 10 MHz and utilizes a 100-pin LQFP package. It functions as a multichannel I/O controller compatible with the Z80 family.

Specialized Feature Summary

• Integrates two independent synchronous/asynchronous serial channels
• Includes three 8-bit parallel ports for general-purpose I/O
• Features four independent counter/timer channels
• Supports software/hardware resets and programmable interrupt priorities

Specialized Applications

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

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the presence of the 'TR' suffix indicating tape and reel packaging if required for automated assembly processes. Ensure compatibility with existing system voltage levels and clock requirements before procurement.

Specialized Selection Notes

Select this model when a 10 MHz operating frequency is required within the Z84C90 series. The 100-pin LQFP package is suitable for surface-mount applications requiring higher pin counts than the PLCC option. Verify that the system design accommodates the specific pinout configuration provided in the datasheet diagrams.

Specialized Part Context

This component belongs to the Z84C90 KIO family, which consolidates multiple Zilog peripherals into one unit. It serves as a comprehensive solution for systems needing integrated serial, parallel, and timer functionalities without requiring separate discrete chips.

Specialized Replacement Considerations

Compatible variants include Z84C9008ASC (8 MHz) and Z84C9012VSC (12 MHz). Substitution requires verification of clock speed compatibility and package footprint differences between LQFP and PLCC options.
