Z8018008VEC

Overview

The Z8018008VEC is an 8-bit microprocessor unit based on the Z80 architecture, operating at a maximum clock frequency of 8 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 temperature range from -40°C to +100°C. Internal memory includes 64 kB of SRAM. Integrated peripherals consist of two DMA channels, two UARTs, two programmable reload timers, and an MMU supporting up to 1 MB of addressable memory.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 devices while incorporating extended instructions.
• Integrates system functions including DMA controllers, UARTs, timers, wait-state generators, and an interrupt controller on-chip.
• Features an expanded Memory Management Unit (MMU) allowing access to up to 1 MB of physical memory.
• Includes low power-down modes and an internal oscillator/generator for simplified system design.

Applications

• Industrial control systems requiring robust I/O integration
• Embedded applications needing extended memory addressing capabilities
• Systems utilizing asynchronous serial communication interfaces

Procurement Notes

Verify the specific suffix 'VEC' against official Zilog documentation to confirm the exact package type, lead-free status, and temperature grade. Ensure that the 68-pin PLCC footprint matches the target PCB design. Confirm availability status as this component may be subject to end-of-life restrictions or limited supply conditions.

Selection Notes

Select this component when Z80 code compatibility is required alongside integrated peripheral resources. Consider the 68-pin PLCC package for surface-mount assembly requirements. Evaluate the need for the extended temperature range (-40°C to +100°C) versus commercial grades. Verify that the 8 MHz speed meets the processing demands of the application.

Part Context

The Z80180 series belongs to the Z180 family of enhanced microprocessors. These units combine a high-performance CPU core with various system and I/O resources. The series offers object-code compatibility with the Z80 CPU while providing additional features such as DMA, timers, and serial ports to reduce external component counts in embedded designs.

Replacement Considerations

Consult official Zilog documentation for confirmed substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when considering alternatives from other manufacturers.
