Z8S18010VSG

Overview

The Z8S18010VSG is a static microprocessor unit based on the Z180 core, operating at a maximum clock frequency of 10 MHz. It features an 8-bit data bus and supports up to 1 MB of physical memory via its expanded MMU. The device operates on a 5 V supply voltage and includes two enhanced UARTs, two chain-linked DMA channels, and two programmable reload timers. It is housed in a 68-pin PLCC package with a commercial operating temperature range of 0°C to +70°C.

Feature Summary

• Code compatible with ZiLOG Z80 CPU while offering extended instructions and faster execution speeds.
• Integrated system resources including two chain-linked DMA channels for high-speed data transfers.
• On-chip interrupt controllers and three wait-state generators for flexible bus timing control.
• Low power-down modes including Halt, Sleep, and Power-Down states to reduce energy consumption.

Applications

• Embedded systems requiring backward compatibility with legacy Z80 software.
• Industrial control applications utilizing integrated serial communication interfaces.
• Memory-intensive designs leveraging the onboard MMU for addressing up to 1 MB.
• Real-time processing tasks supported by hardware timer and counter peripherals.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Review product discontinuance notifications for availability constraints and potential obsolescence risks affecting long-term production viability.

Selection Notes

Select this model when Z80 instruction set compatibility is required alongside enhanced Z180 features such as increased memory addressing and integrated I/O. Ensure the 68-pin PLCC package fits the target PCB layout. Verify that the 5 V operating voltage aligns with the system power design and that the commercial temperature range meets environmental requirements.
