Z8018008PSC

Overview

The Z8018008PSC is an 8-bit microprocessor unit based on the Z80 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 8 MHz and requires a 5 V supply voltage. The device features a 64 kB SRAM memory type and includes two UARTs, two 16-bit counter/timers, and two DMA channels. It supports SCI and UART interfaces and is housed in a 64-pin DIP package designed for through-hole installation. The specified operating temperature range is 0°C to +70°C.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 devices while incorporating reduced system costs through integrated I/O functions.
• Includes on-chip resources such as DMA controllers, UARTs, timer channels, wait-state generators, a clock oscillator, and an interrupt controller.
• Features an expanded MMU addressing capability supporting up to 1 MB of memory space.

Applications

• Embedded systems requiring Z80 code compatibility
• Industrial control applications
• Communication equipment utilizing UART interfaces

Procurement Notes

Verify component authenticity and datasheet revision levels prior to integration. Confirm that the specific ordering suffix matches the required package style and environmental specifications. Ensure design compliance with absolute maximum ratings and DC characteristics defined in the official product specification document PS014005-0817.

Selection Notes

Select this variant when an 8 MHz operational speed is sufficient for the application requirements. The 64-pin DIP package is suitable for through-hole PCB designs. Consider alternative suffixes if extended temperature ranges or surface-mount packaging options are necessary for the target environment.
