Z8018006FSG

Overview

The Z8018006FSG is an 8-bit microprocessor unit based on the Z80 architecture, operating at a maximum clock frequency of 6 MHz. It features an integrated memory management unit supporting up to 1 MB of addressable space and includes two DMA channels for high-speed data transfers. The device incorporates two asynchronous serial communication interface (ASCI) channels with programmable baud rate generators and modem control signals. Additionally, it contains two 16-bit programmable reload timers and a clocked serial I/O channel. The component utilizes SRAM storage and operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Provides full backward compatibility with existing Zilog Z80 CPU instruction sets while offering extended instructions and enhanced performance.
• Integrates system-level functions including dual DMA controllers, interrupt controllers, wait-state generators, and an internal clock oscillator to reduce external component requirements.
• Features expanded memory addressing capabilities through an on-chip MMU that maps logical 64 KB into a 1 MB physical address space.
• Includes comprehensive serial communication resources with two full-duplex UARTs and a half-duplex clocked serial I/O channel.

Applications

• Industrial control systems requiring robust serial communication and timer functions
• Embedded applications needing direct memory access for high-speed peripheral interfacing
• Systems utilizing legacy Z80 codebases requiring extended memory addressing

Procurement Notes

Verify the specific suffix 'FSG' against official Zilog documentation to confirm package type and environmental compliance. Confirm lead-free status as indicated in revision history. Check current product lifecycle status as discontinuance notifications may apply. Ensure moisture sensitivity levels are accounted for during handling and storage procedures.

Selection Notes

Select this component when Z80 code compatibility is required alongside integrated peripherals. Consider the 80-pin QFP package for surface mount applications. Evaluate the need for the specific 6 MHz speed grade versus higher frequency variants. Verify that the commercial temperature range meets the operational environment requirements.

Part Context

This part belongs to the Z80180 series of microprocessors, which combine a Z80-compatible CPU core with extensive on-chip peripherals. The series is designed to reduce system costs by integrating DMA, UART, timers, and memory management units directly onto the silicon die, eliminating the need for multiple discrete controller chips.

Replacement Considerations
