Z8018010VEG

Overview

The Z8018010VEG is an 8-bit microprocessor unit based on the Z80 architecture, operating at a maximum clock frequency of 10 MHz. It features a single core with an 8-bit data bus width and utilizes a 68-pin PLCC package for surface mount installation. The device operates within a voltage range of 5 V and supports an extended industrial temperature range from -40°C to +100°C. Internal resources include 64 kB of SRAM, two DMA channels, two UARTs, and two programmable timers.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 CPU code while offering an extended instruction set.
• Integrates multiple system functions on-chip, including DMA controllers, asynchronous serial communication interfaces, and interrupt controllers.
• Supports expanded memory addressing up to 1 MB through an integrated Memory Management Unit (MMU).
• Includes low power-down modes and three on-chip wait-state generators to optimize system performance and energy consumption.

Applications

• Industrial control systems requiring robust I/O integration
• Embedded applications utilizing extended memory addressing
• Systems requiring high-speed direct memory access operations

Procurement Notes

Verify component authenticity and physical condition upon receipt, as this part is listed as End-of-Life. Confirm that the 68-pin PLCC footprint matches your PCB design requirements. Ensure handling procedures account for moisture sensitivity levels specified in the datasheet to prevent damage during soldering.

Selection Notes

Select this variant specifically for its 10 MHz speed grade and extended temperature capability (-40°C to +100°C). The 'VEG' suffix indicates the lead-free environmental flow and the 68-pin PLCC package style. Compare against other Z80180 variants if different package types or standard commercial temperature ranges are sufficient for your application.

Part Context

This component belongs to the Z80180 family of microprocessors, which combine a Z80-compatible CPU core with extensive peripheral support. The family offers reduced system costs by integrating DMA, UARTs, and timers directly onto the silicon die, eliminating the need for external interface chips in many designs.
