Z8S18033FSG

Overview

The Z8S18033FSG is a static microprocessor based on the Z180 core, manufactured by ZiLOG. It features an 8-bit data bus and operates at a maximum clock frequency of 33 MHz with a 5 V supply voltage. The device is housed in an 80-pin QFP package designed for surface mount installation. It supports an operating temperature range from 0°C to +70°C. Key specifications include two timer/counters, SCI interface capability, and ROMless storage type.

Feature Summary

• Provides full backward compatibility with existing ZiLOG Z80 devices while offering extended instructions and faster execution speeds.
• Integrates two chain-linked DMA channels that allow for nonstop operation between channels when requesting from the same peripherals.
• Includes two enhanced asynchronous serial communication interfaces (ASCI) with FIFO buffers and baud rate generators supporting up to 512 Kbps.
• Offers multiple low-power-down modes including Stop, Sleep, and Power-Down to reduce current consumption during idle states.

Applications

• Embedded systems requiring Z80 code compatibility with enhanced I/O resources
• Industrial control applications utilizing DMA for high-speed data transfers
• Communication equipment employing asynchronous serial interfaces

Procurement Notes

Verify component authenticity through official manufacturer documentation or authorized distributors. Confirm RoHS compliance status and moisture sensitivity level prior to soldering. Ensure proper handling procedures are followed due to humidity sensitivity. Check for obsolescence notices or product change notifications affecting availability or specifications.

Selection Notes

Select this model when Z80 instruction set compatibility is required alongside integrated DMA and serial communication capabilities. Consider the 80-pin QFP package for surface mount designs. Evaluate power consumption requirements against available low-power modes. Verify voltage levels match system design constraints.

Part Context
