Z8S18010VEC

Overview

The Z8S18010VEC is an 8-bit microprocessor IC from the Z180 family, manufactured by Zilog. It features a single core with a maximum clock speed of 10 MHz and operates within a voltage range of 5.0V for I/O. The device is housed in a 68-pin PLCC (J-lead) surface-mount package. It supports an operating temperature range of -40°C to +100°C. Key integrated peripherals include two DMA channels, two ASCI interfaces, two UARTs, and two timer/counters.

Feature Summary

• Code compatible with ZiLOG Z80 CPU while offering extended instructions and faster execution speeds.
• Features two chain-linked DMA channels for nonstop high-speed data transfers between memory and I/O devices.
• Includes on-chip interrupt controllers and three wait-state generators for flexible system timing control.
• Supports low power-down modes including Stop, Sleep, and Standby to reduce energy consumption.

Applications

• Embedded systems requiring backward compatibility with legacy Z80 software.
• Industrial control applications utilizing integrated serial communication interfaces.
• Data acquisition systems leveraging on-chip DMA and timer resources.
• Battery-powered devices benefiting from multiple low-power operational modes.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinuation status. Confirm specific lot codes and packaging integrity upon receipt. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent damage prior to soldering. Review official product discontinuance notifications for final purchase timelines and last-time buy information.

Selection Notes

Select this model when Z80 instruction set compatibility is mandatory alongside enhanced peripheral integration. Consider the 68-pin PLCC package for surface-mount assembly constraints. Evaluate the 10 MHz speed against system timing requirements. Verify that the 5V I/O logic levels match the target board's voltage domains. Assess if the integrated UARTs and DMA channels eliminate the need for external support chips.

Part Context

This component belongs to the Z8S180/Z8L180 enhanced microprocessor family, which improves upon the original Z80180 design. It combines a high-performance CPU core with extensive on-chip resources, reducing system component count. The Z180 architecture maintains object-code compatibility with the Z80 while adding features like an MMU and expanded addressing capabilities up to 1 MB.

Replacement Considerations

Check for Z8S180 series variants with different speed grades or packages. Verify pin-to-pin compatibility with Z80180 models if legacy code requires minimal modification. Consult official substitution lists for any updated revisions within the same family line.
