Z84C0020PEC

Overview

The Z84C0020PEC is a microprocessor based on the Z80 architecture, manufactured by Zilog. It features an 8-bit data bus width and operates at a maximum clock frequency of 20 MHz. The device utilizes CMOS technology and requires a 5 V operating supply voltage. It is housed in a 40-pin DIP package and supports surface mount or through-hole installation styles depending on specific variant configurations. The component functions as a central processing unit within embedded systems.

Feature Summary

• Implements the Z80 processor core architecture for instruction execution
• Utilizes CMOS technology for power efficiency compared to NMOS variants
• Provides standard I/O interface capabilities including UART functionality

Applications

• Embedded control systems requiring Z80 compatibility
• Industrial automation controllers
• Legacy system maintenance and replacement

Procurement Notes

Verify RoHS compliance status as sources indicate conflicting information regarding lead-free certification. Confirm package type accuracy between DIP-40 and PLCC-44 variants before ordering. Check current availability as some listings indicate limited stock or obsolete status. Ensure supplier documentation matches the specific suffix requirements for your application needs.

Selection Notes

Select this component when a static Z80 CPU with 20 MHz performance is required. Compare against Z84C0020AEG if a QFP package is preferred over DIP. Consider power consumption differences between NMOS and CMOS generations. Verify voltage tolerance ranges match the target circuit design specifications.

Part Context

This part belongs to the Z84 series of microprocessors derived from the classic Z80 instruction set. It represents the CMOS evolution of the original NMOS Z80 CPU, offering improved power characteristics. The Z84C0020PEC serves as a drop-in replacement for older NMOS versions in compatible designs while providing enhanced electrical specifications.

Replacement Considerations

Z84C0020AEG is a documented alternative offering identical functional specifications in a 44-LQFP package instead of the 40-DIP form factor.
