Z8018216ASG

Overview

The Z8018216ASG is a static microprocessor unit (MPU) from the Z80182 series, manufactured by Zilog. It integrates a Z8S180 MPU core with two ESCC channels, three 8-bit parallel I/O ports, and a 16550 MIMIC interface for direct PC/XT/AT bus connection. The device operates at a maximum clock frequency of 16 MHz and requires a 5 V supply voltage. It features an 8-bit data bus width and utilizes SRAM storage type. The component is housed in a 100-pin QFP package designed for surface mount installation.

Feature Summary

• Integrates a fully static Z8S180 MPU core compatible with Z80/Z180 instruction sets
• Includes two Enhanced Serial Communications Controller (ESCC) channels with 32-bit CRC support
• Provides a 16550 MIMIC interface enabling direct connectivity to IBM PC, XT, and AT buses
• Features on-chip wait state generators and individual RAMCS/ROMCS control

Applications

• Modem applications including V.Fast implementations
• Fax machine controller systems
• Voice messaging equipment
• General communications peripheral controllers

Procurement Notes

Verify the specific suffix 'ASG' against the manufacturer datasheet DS971820600 to confirm pinout and electrical characteristics match the standard Z80182QFP variant. Confirm availability status as this model may be discontinued or subject to limited supply constraints. Ensure environmental compliance documentation is obtained prior to integration.

Selection Notes

Select this component when a static Z80-compatible processor with integrated serial communication controllers is required. It is suitable for designs needing direct legacy PC bus interfacing via the 16550 MIMIC mode. Consider the 100-pin QFP package constraints and 5V operating voltage requirements during PCB layout and power supply design.

Part Context

This part belongs to the Z80182/Z8L182 Intelligent Peripheral Controller (ZIP) family. It combines the processing power of the Z180 MPU with specialized communication peripherals. The series is designed to reduce system component count by integrating memory interfaces, timers, and serial controllers onto a single CMOS chip.
