Z8018010VSG

Overview

The Z8018010VSG 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 SRAM for storage. The device operates within a voltage range of 4.5 V to 5.5 V and supports an extended industrial temperature range from -40°C to +100°C. It is housed in a PLCC-68 package designed for surface mount technology. Integrated peripherals include two UARTs, two 16-bit timers, and DMA channels.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 devices while incorporating reduced system costs through on-chip integration of key functions.
• Includes integrated direct memory access controllers, asynchronous serial communication interfaces, programmable reload timers, wait-state generators, and an interrupt controller.
• Supports expanded memory addressing up to 1 MB via an on-chip memory management unit.

Applications

• Industrial control systems requiring robust environmental tolerance
• Embedded applications needing integrated I/O and memory management
• Legacy Z80 system upgrades seeking enhanced performance

Procurement Notes

Verify the specific suffix 'VSG' against official datasheets to confirm lead-free compliance and extended temperature ratings. Confirm package type matches PLCC-68 requirements. Check current lifecycle status as this component may be subject to discontinuation or last-time buy notices.

Selection Notes

Select this model when a 10 MHz processing speed is required alongside integrated UART and timer resources. Ensure the design accommodates the PLCC-68 surface mount footprint. Verify that the 4.5 V to 5.5 V operating voltage aligns with the target power supply rails.

Part Context

This component belongs to the Z80180 series of microprocessors, which are enhancements of the classic Z80 CPU. The series integrates standard peripheral functions directly onto the silicon die to minimize external component count. The Z8018010 variant specifically denotes the 10 MHz clock speed option within this family.

Replacement Considerations

Consult official documentation for confirmed substitute part numbers. Cross-reference pinouts and electrical characteristics carefully before substitution.
