Z8S18020VSG

The Z8S18020VSG is an 8-bit microprocessor IC based on the Z8S180 core from Zilog's Z180 Static (Z8S180) series. It operates at 20 MHz and is supplied with 5 V I/O, delivering a compact, single-core processing solution for commercial embedded designs.

Featuring an on-chip DRAM controller and ASCI interface in a 68‑PLCC surface-mount package, this device targets embedded and commercial applications that require a straightforward, Z180-series compatible MPU in a PLCC form factor.

Key Features

• Core & Performance Z8S180 core with a single 8-bit processing core running at 20 MHz for deterministic embedded control tasks.
• Memory Controllers Integrated DRAM controller to support external dynamic memory configurations where required by the application.
• Interfaces Includes ASCI to support serial communications and peripheral interfacing in embedded systems.
• Power 5 V I/O supply requirement compatible with legacy and many commercial logic-level environments.
• Package & Mounting 68‑PLCC (J‑Lead) supplier device package designed for surface-mount assembly.
• Operating Range & Grade Commercial grade device with an operating temperature range of 0 °C to 70 °C.
• Environmental Compliance RoHS compliant.

Typical Applications

• Embedded Controllers — Use as the main MPU in commercial embedded control systems that require an 8-bit Z8S180 core at 20 MHz.
• Consumer and Commercial Electronics — Suitable for control and interface tasks in consumer or commercial devices operating within the 0 °C to 70 °C range.
• Legacy System Upgrades — Replacement or refurbishment of PLCC-mounted Z180-series designs that benefit from an integrated DRAM controller and ASCI interface.
• Development and Prototyping — Practical choice for designers working with the Zilog Z180 Static family who need a surface-mount 68‑PLCC package.
