Z8018110FEC

Overview

The Z8018110FEC is an 8-bit microprocessor from the Z80181 series, featuring a Z180-compatible core with a 10 MHz maximum clock frequency. It integrates a Memory Management Unit (MMU) for 1MB addressable space, one Serial Communication Controller (SCC), two DMA channels, and two 16-bit timers. The device includes two 8-bit parallel ports and operates within a 4.5V to 5.5V voltage range. Packaged in a 100-pin QFP, it supports asynchronous and synchronous serial protocols.

Feature Summary

• Integrates a Z180-compatible MPU core with enhanced instruction set and MMU for extended memory access.
• Includes on-chip Serial Communication Controller (SCC) supporting multiple asynchronous and synchronous protocols.
• Features two independent DMA controllers for high-speed data transfers between memory and I/O devices.
• Combines programmable reload timers, counter/timer logic, and general-purpose parallel ports in a single package.

Applications

• Intelligent communication control applications
• Terminal systems
• Printer controllers
• Modem interfaces
• Slave communication processors for multi-bit MPU systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for Product Change Notifications (PCN) or End-of-Life (EOL) notices prior to procurement. Ensure storage conditions account for moisture sensitivity levels specified in the datasheet to prevent damage during assembly.

Selection Notes

Select this component when system requirements demand a high-performance 8-bit processor with integrated communication peripherals. It is suitable for designs needing extensive memory mapping capabilities via the MMU. Consider the 100-pin QFP package constraints and thermal management requirements for the operating temperature range during PCB layout.

Part Context

The Z80181 belongs to the Zilog Smart Access Controller (SAC) family, utilizing Superintegration methodology. It combines discrete Z180, Z85C30, and Z84C30 functionalities into one chip. This integration reduces board space and simplifies design for complex embedded control tasks requiring robust serial and parallel I/O handling.

Replacement Considerations

Check for Z80181 variants with different speed grades or packaging options. Verify software compatibility if substituting with other Z180-family members. Ensure pinout and register mappings remain identical to avoid hardware redesign.
