Z8S18020PSC1960

The Z8S18020PSC1960 is an 8-bit microprocessor from the Zilog Z8S180 Static series. It implements a single Z8S180 core running at 20 MHz and is supplied in a 64-pin DIP package for through-hole mounting.

Designed for embedded applications, this commercial-grade MPU offers 5 V I/O compatibility, an integrated DRAM controller, and an ASCI interface, making it suitable for systems that require a classic DIP form factor and straightforward serial connectivity.

Key Features

• Core & Performance  Single Z8S180 core with an 8-bit bus width operating at up to 20 MHz for deterministic, low-complexity processing.
• Power & I/O  5 V I/O voltage level compatibility for systems using standard 5 V logic.
• Memory Support  Integrated DRAM controller to simplify external memory interfacing and reduce supporting logic.
• Interfaces  Includes an ASCI interface for serial communication requirements.
• Package & Mounting  64-pin DIP (0.750", 19.05 mm) through-hole package for ease of prototyping, socketed installations, and legacy PCB designs.
• Operating Range & Grade  Commercial-grade device with an operating temperature range of 0 °C to 70 °C.
• Compliance  RoHS compliant.

Typical Applications

• Embedded control systems  Use the Z8S18020PSC1960 where an 8-bit microcontroller with serial I/O and DRAM support is required for control and sequencing tasks.
• Through-hole and retrofit projects  The 64-DIP package and through-hole mounting suit prototyping, educational boards, and legacy system replacements.
• Systems requiring 5 V I/O  Applies to designs that operate with standard 5 V logic levels and need an integrated DRAM controller.
