Z84C0008VEC00TR

Overview

The Z84C0008VEC00TR is a microprocessor IC based on the Z80 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 8 MHz and features an 8-bit data bus width. The device is housed in a 44-PLCC surface-mount package with J-leads. It requires a single 5V supply voltage for operation. The component is designed for industrial temperature ranges, supporting environments from -40°C to +100°C. It includes integrated UART interface capabilities for serial communication.

Feature Summary

• Implements the Z80 instruction set architecture within a CMOS process.
• Provides integrated UART functionality for serial data transmission and reception.
• Supports extended industrial operating temperature ranges for robust performance.

Applications

• Industrial control systems requiring reliable 8-bit processing
• Embedded applications utilizing serial communication interfaces
• Legacy system maintenance and replacement scenarios

Procurement Notes

Verify the specific suffix 'C00TR' against official Zilog documentation to confirm tape-and-reel packaging and exact electrical characteristics. Confirm RoHS compliance status as historical Zilog PLCC parts may vary. Check for active discontinuation notices or product change notifications prior to procurement. Ensure the 44-PLCC footprint matches the target PCB design constraints.

Selection Notes

Select this component when a Z80-compatible processor with integrated UART is required in a PLCC package. Consider the 8 MHz speed limit and 5V supply requirements during system design. Evaluate thermal management needs for the specified industrial temperature range. Compare pinout compatibility with existing designs if replacing older NMOS variants.

Part Context

This part belongs to the Z84C00 series of Z80-based microprocessors. It represents the CMOS version of the classic Z80 CPU, offering lower power consumption compared to earlier NMOS implementations. The series is widely recognized in embedded computing history for its compatibility with the Intel 8080 instruction set while providing enhanced features.

Replacement Considerations

Direct substitutes include other Z84C0008 variants such as Z84C0008VEG or Z84C0008AEG, provided the package type (PLCC vs QFP) and suffix specifications match. Verify that any replacement maintains the same UART integration and clock speed requirements.
