Z8018008VSC

Overview

The Z8018008VSC is an enhanced microprocessor unit based on the Z80 architecture, manufactured by Zilog. It operates at a maximum clock frequency of 8 MHz with an 8-bit data bus width and integrates 64 kB of SRAM. The device utilizes a 68-pin PLCC package for surface mount installation. It functions within a supply voltage range of 5 V and supports an operating temperature range from 0°C to +70°C. Key interfaces include SCI and UART, alongside two timer/counters.

Feature Summary

• Integrates 64 kB of static RAM directly onto the die for embedded control applications.
• Includes built-in serial communication interfaces supporting SCI and UART protocols.
• Features dual programmable timer/counters for system timing and event counting.

Applications

• Industrial automation controllers requiring integrated memory and I/O.
• Embedded systems utilizing standard Z80 software architectures.
• Communication equipment needing onboard serial interface capabilities.

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package integrity as moisture sensitivity requires proper handling. Check RoHS compliance documentation against specific project requirements. Ensure compatibility with existing PCB footprints for 68-PLCC packages. Validate thermal performance within the specified commercial temperature range.

Selection Notes

Select this component when a Z80-compatible core with integrated SRAM is required. Consider the 68-PLCC package for surface-mount assembly constraints. Evaluate the 8 MHz speed against application processing needs. Verify that the 5 V logic levels match the system design. Assess the availability of replacement sources given the discontinued status.
