Z8S18010PSC

Overview

The Z8S18010PSC is an 8-bit microprocessor based on the Z180 core, operating at a maximum clock frequency of 10 MHz. It features a single core with an 8-bit data bus width and supports up to 1 MB of addressable memory via its Memory Management Unit. The device operates within a temperature range of 0°C to +70°C and utilizes a 64-pin DIP package. Key integrated peripherals include two DMA channels, two asynchronous serial communication interfaces (ASCI), two programmable reload timers, and a clocked serial I/O channel.

Feature Summary

• Code compatible with ZiLOG Z80 CPU while offering extended instructions and faster execution speeds.
• Features two chain-linked DMA channels for high-speed data transfers between memory and I/O devices.
• Includes two enhanced UARTs with baud rate generators supporting asynchronous data transfer rates up to 512 Kbps.
• Provides three low power-down modes to reduce energy consumption during idle or specific operational states.

Applications

• Embedded systems requiring backward compatibility with legacy Z80 software.
• Industrial control applications utilizing on-chip interrupt controllers and timer resources.
• Communication equipment leveraging dual ASCI channels for serial data handling.
• Memory-intensive designs benefiting from expanded MMU addressing capabilities.

Procurement Notes

Verify component authenticity through official manufacturer documentation or authorized distributors. Confirm package integrity and pin alignment against the 64-DIP specification. Check for obsolescence notices as this series may be subject to discontinuation. Ensure environmental compliance requirements match project specifications prior to acquisition.

Selection Notes

Select this model when Z80 instruction set compatibility is required alongside enhanced peripheral integration. Consider the 10 MHz speed rating relative to system timing constraints. Evaluate the 64-pin DIP form factor for through-hole mounting requirements. Assess the need for on-chip DMA and serial interfaces to minimize external component count.
