Z8018233FSG1838

Overview

The Z8018233FSG1838 is a static microprocessor from the Z80182 series, operating at 33 MHz with a 5 V supply. It integrates a Z80 core within a 100-pin QFP package. The device includes 64 kB of SRAM and provides 24 I/O lines. Key peripherals consist of two UART channels, two timer/counters, and an ESCC interface. It supports SMD/SMT mounting and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates a fully static Z80 MPU core with on-chip wait state generators and clock oscillator.
• Features dual ESCC channels equipped with 32-bit CRC capabilities for enhanced serial communication.
• Includes a 16550 compatible MIMIC interface designed for direct connection to PC, XT, and AT buses.
• Provides three 8-bit parallel I/O ports alongside two DMA channels for efficient data transfer.

Applications

• V. Fast modem applications
• Fax equipment
• Voice messaging systems
• Communications controllers

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for End-of-Life (EOL) notices prior to procurement. Ensure storage conditions account for moisture sensitivity levels specified in the datasheet. Validate pin compatibility with existing PCB footprints before ordering.

Selection Notes

Select this component when a static Z80 architecture is required for legacy system integration. Consider the 33 MHz speed and 5 V operation for standard logic environments. Evaluate the need for the integrated 16550 MIMIC interface if PC bus compatibility is essential. Verify that the 100-pin QFP package fits the available board space constraints.

Part Context

This part belongs to the Zilog Z80182 Intelligent Peripheral Controller family. It combines the Z8S180 MPU core with Z85230 ESCC channels and parallel I/O. The device is designed to replace discrete controller solutions by integrating memory, timers, and serial interfaces into a single chip.

Replacement Considerations

Consult official substitution lists for verified equivalents. Cross-reference pinouts and electrical specifications carefully. Ensure software compatibility with the target application before replacing the component.

FAQ

What is the function of the EV1 and EV2 pins?

These pins determine the emulation mode of the Z180 MPU, allowing selection between normal operation, emulation adapter mode, and emulator probe mode.

How does the 16550 MIMIC interface operate?

It allows direct connection to IBM PC, XT, and AT buses by mimicking the functionality of a standard 16550 UART chip, facilitating data compression and error correction.
