Z8S18020VSG00TR

Overview

The Z8S18020VSG is a microprocessor based on the Z180 core, manufactured by ZiLOG. It features an 8-bit data bus width and operates at a maximum clock frequency of 20 MHz. The device functions with a supply voltage of 3.3 V and utilizes a PLCC-68 package for surface mount installation. It supports an operating temperature range from 0°C to +70°C. Key integrated peripherals include two timers/counters and a UART interface. The component does not include a watchdog timer.

Feature Summary

• Integrates a Z180 processor core with static logic design for reliable operation.
• Includes built-in serial communication capabilities via a UART interface.
• Features dual hardware timers and counters for system timing control.

Applications

• Industrial control systems requiring robust microprocessing
• Embedded applications utilizing serial communication protocols
• General-purpose microprocessor designs in commercial electronics

Procurement Notes

Verify availability status carefully as this component may be discontinued or subject to limited supply constraints. Confirm that the PLCC-68 package matches your PCB footprint requirements. Ensure that the 3.3 V I/O voltage levels are compatible with your system's peripheral devices. Check for any specific environmental certifications required for your deployment region.

Selection Notes

Select this part when a Z180-compatible architecture is required with a 20 MHz performance ceiling. Consider the PLCC-68 package if through-hole or specific SMD mounting styles are preferred over QFP options. Verify that the absence of a watchdog timer meets your system safety requirements. Compare against other Z8S180 variants if different packaging or temperature ranges are needed.

Part Context

This component belongs to the Z8S180 series of microprocessors, which are enhanced versions of the classic Z80 architecture. The series is designed for high-performance embedded applications. The Z8S18020VSG specifically denotes the 20 MHz speed grade and 3.3 V operating voltage within this family. It shares architectural similarities with other members like the Z8L180 series but differs in power consumption characteristics and package options.
