Z8018006VEC00TR

Overview

The Z8018006VEC00TR is an 8-bit microprocessor unit based on the Z80 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 6 MHz and supports a 6.144 MHz CPU clock operation. The device features an integrated memory management unit (MMU) for extended addressing up to 1 MB, two DMA channels, two asynchronous serial communication interface (ASCI) UARTs, two programmable reload timers, and a clocked serial I/O channel. It includes on-chip wait-state generators, an oscillator, and interrupt controllers. The component utilizes SRAM storage and functions within a 5 V operating voltage range. It is housed in a 68-pin PLCC package with surface mount installation.

Feature Summary

• Code compatible with Zilog Z80 CPU with extended instructions
• Integrated MMU supporting up to 1 MB address space
• Dual DMA channels for high-speed data transfers
• On-chip ASCI, CSIO, and timer resources

Applications

• Embedded control systems requiring Z80 compatibility
• Industrial automation equipment
• Communication devices utilizing UART interfaces
• Memory-intensive applications using MMU mapping

Procurement Notes

Verify the specific suffix '00TR' against official Zilog documentation to confirm tape-and-reel packaging status, as standard datasheets may list tube packaging for this series. Confirm lead-free environmental compliance ('G' suffix) if required, noting that revision history indicates updates to ordering information regarding environmental flow. Ensure the 6 MHz speed grade matches system timing requirements.

Selection Notes

Select this variant for designs requiring a 6 MHz operational speed with a 68-pin PLCC footprint. Consider the 6.144 MHz CPU clock capability for precise baud rate generation. Evaluate the need for the integrated MMU and dual DMA channels to reduce external component count compared to standard Z80 implementations. Verify temperature range suitability for the intended environment.

Part Context

The Z80180 belongs to the Z180 family of enhanced microprocessors, combining Z80 compatibility with additional on-chip peripherals. This family addresses the need for reduced system costs by integrating functions like DMA, UARTs, and timers directly onto the silicon die. The Z80180 specifically offers extended memory addressing capabilities not present in the original Z80 architecture.

Replacement Considerations

Z8018006VSG: Different package (PLCC-68 vs DIP-64), same speed. Z8018008PSC: Higher speed (8 MHz). Z8S18010VEG: Static version, higher speed (10 MHz). Verify pinout and electrical characteristics before substitution.
