Z8018233ASC

Overview

The Z8018233ASC is a static microprocessor unit (MPU) from the Z80182 family, operating at a maximum clock frequency of 33 MHz. It features an 8-bit data bus width and utilizes a 100-pin QFP package for surface mount installation. The device operates on a 5 V supply voltage within a commercial temperature range of 0°C to +70°C. Key internal resources include two UART channels, two 16-bit timer counters, and an on-chip interrupt controller.

Feature Summary

• Integrates a Z8S180 MPU core with code compatibility to Zilog Z80/Z180 architectures.
• Includes two ESCC channels supporting 32-Bit CRC and full duplex DMA transfers.
• Provides a 16550 compatible MIMIC interface for direct connection to PC, XT, and AT buses.
• Features three 8-bit parallel I/O ports and individual wait state generators for RAMCS and ROMCS.

Applications

• Modem applications, specifically V. Fast implementations
• Fax machine control systems
• Voice messaging equipment
• General communications peripheral controllers

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for moisture sensitivity handling requirements prior to assembly. Ensure pinout alignment with the 100-pin QFP specification during PCB design validation.

Selection Notes

Select this component when system requirements demand high-speed serial communication combined with standard PC bus emulation capabilities. The integrated ESCC and MIMIC interfaces reduce external component count. Verify that the 33 MHz operating speed meets the processing latency constraints of the target application environment.
