Z8018216ASG1838

Overview

The Z8018216ASG1838 is a static microprocessor unit (MPU) from the Zilog Z80182 family, operating at a maximum clock frequency of 33 MHz. It features an 8-bit data bus width and utilizes a QFP-100 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. Internal memory includes 64 kB of SRAM data storage. Peripheral integration consists of two UART channels, two timer/counters, and 24 bits of parallel I/O capability.

Feature Summary

• Integrates a fully static Z8S180 MPU core with code compatibility to Z80/Z180 architectures.
• Includes dual ESCC channels supporting 32-bit CRC and full-duplex DMA transfers.
• Provides a 16550 MIMIC interface enabling direct connection to PC, XT, and AT buses.
• Features three independent 8-bit parallel I/O ports with configurable bit-level direction.

Applications

• V. Fast modem applications requiring high-speed serial communication
• Fax machines utilizing integrated error correction and data compression
• Voice messaging systems managing multiple serial channels
• Industrial controllers interfacing directly with legacy PC/XT/AT bus architectures

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to end-of-life status. Confirm RoHS compliance details via official documentation as specifications may vary by revision. Validate pinout compatibility with existing PCB footprints before procurement. Ensure proper handling procedures are followed given moisture sensitivity classification.

Selection Notes

Select this component when system requirements demand a static processor with integrated high-performance serial controllers. Consider the 16550 MIMIC interface if legacy PC bus compatibility is necessary without external logic. Evaluate the 64 kB internal SRAM against external memory expansion needs. Verify that the 33 MHz operating speed aligns with thermal management capabilities in the target enclosure.

Part Context

This part belongs to the Z80182 Intelligent Peripheral Controller (ZIP) series designed for communications applications. It combines a Z8S180 MPU core with Z85230 ESCC peripherals and parallel I/O. The family targets embedded control tasks in modems, fax, and voice equipment where high integration reduces board space and component count compared to discrete solutions.
