Z84C0020AEG

Overview

The Z84C0020AEG is a microprocessor unit (MPU) based on the Z80 core architecture, manufactured by Zilog. It operates at a maximum clock speed of 20 MHz with an 8-bit data bus width and a 16-bit address bus. The device is housed in a 44-LQFP package measuring 10x10 mm and supports surface mount mounting. It functions within a supply voltage range of 5.0V for I/O and operates across an industrial temperature range from -40°C to +100°C. The component is RoHS3 compliant and classified as obsolete.

Feature Summary

• Implements the standard Z80 instruction set architecture for backward compatibility
• Supports low power operation modes
• Features integrated UART interface capabilities

Applications

• Industrial control systems requiring robust 8-bit processing
• Embedded applications utilizing serial communication via UART
• Legacy system maintenance and replacement

Procurement Notes

Verify component authenticity due to obsolete status. Confirm RoHS3 compliance requirements against specific project regulations. Check for moisture sensitivity level handling procedures during storage and assembly. Validate package dimensions against PCB footprint specifications prior to procurement.

Selection Notes

Select this component when a Z80-compatible processor with integrated UART functionality is required. Ensure the design accommodates the 44-LQFP surface mount package constraints. Verify that the 5V logic levels align with peripheral interfaces. Consider the extended industrial temperature range suitability for harsh environments.

Part Context

This part belongs to the Z84C00 series of CMOS microprocessors. It serves as a direct successor to earlier NMOS Z80 variants, offering improved power efficiency and higher operating speeds. The AEG suffix denotes specific packaging and environmental compliance characteristics within the Zilog product line.
