Z8018008PSG

Overview

The Z8018008PSG is an 8-bit microprocessor unit based on the Z80 core, operating at a maximum clock frequency of 8 MHz. It features a 64 kB SRAM data memory and supports a 5 V supply voltage within a commercial temperature range of 0°C to +70°C. The device integrates two DMA channels, two UARTs, two programmable reload timers, and a clocked serial I/O port. It utilizes a 64-pin DIP package for through-hole mounting.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 devices while incorporating reduced system costs via integrated peripherals.
• Includes expanded MMU addressing capabilities supporting up to 1 MB of physical memory space.
• Integrates dual asynchronous serial communication interfaces (ASCI) with programmable baud rate generators and modem control signals.

Applications

• Embedded systems requiring Z80 code compatibility with integrated peripheral management
• Industrial control applications utilizing on-chip DMA and timer resources
• Communication equipment employing dual UART functionality

Procurement Notes

Verify component authenticity and datasheet revision alignment prior to integration. Confirm that the specific ordering suffix corresponds to the required lead-free environmental flow and package configuration. Ensure design compliance with the manufacturer's life support policy restrictions.

Selection Notes

Select this variant when a 64-pin DIP package is required for through-hole assembly. Choose this model over QFP or PLCC options if board layout constraints favor dual in-line packaging. Verify that the 8 MHz speed grade meets the system timing requirements.

Part Context

This component belongs to the Z80180 series of enhanced microprocessors. It shares architectural similarities with other members of the family but differs in clock speed, package type, and environmental rating specifications defined by its unique ordering suffix.
