Z8S18020FEC

The Z8S18020FEC is a Zilog Z8S180-series microprocessor featuring a single 8-bit core running at 20 MHz in an 80-QFP surface-mount package. Designed for industrial embedded applications, it combines an established Z180 core architecture with integrated system interfaces and memory controller support to address control, sequencing and communication tasks.

With 5 V I/O, DRAM controller support and an operating temperature range from −40 °C to 100 °C, the device targets environments that require industrial-grade temperature tolerance and board-level integration in a compact 80-BQFP form factor.

Key Features

• Core and Performance Single Z8S180 8-bit core operating at 20 MHz for deterministic control and low-complexity embedded processing.
• Memory Support Integrated DRAM controller capability to simplify system memory interfacing on designs that require external RAM.
• Voltage and I/O 5 V I/O signaling compatible with legacy 5 V systems and common embedded peripherals.
• Interfaces ASCI (asynchronous serial communications interface) for serial device and peripheral communication.
• Package and Mounting 80-pin QFP (80-BQFP / 80-QFP) surface-mount package suitable for compact PCB layouts and automated assembly.
• Industrial Temperature Grade Rated for operation from −40 °C to 100 °C to meet industrial temperature requirements.
• Regulatory RoHS-compliant construction for environmental and regulatory alignment.

Typical Applications

• Industrial Control — Embedded controllers and sequencing logic that benefit from an industrial temperature range and deterministic 8-bit processing.
• Embedded Instrumentation — Data acquisition and instrument front-ends requiring serial communications and external DRAM support.
• Legacy and Maintenance Systems — Replacement or continuation designs that need a 5 V compatible, Z180-family MPU in an 80-QFP package.
