The CS80C286-16 is a 16‑bit microprocessor IC based on the 80C286 core, running at 16 MHz. It delivers integrated memory management and protection features targeted at embedded and consumer systems that require task isolation, virtual memory support and operating‑system level functionality.

Designed as a static CMOS implementation of the 80286 family, the device supports co‑processor acceleration and a high‑bandwidth bus interface while offering surface‑mount deployment in a 68‑pin PLCC package.

Key Features

• Core Architecture 80C286 single 16‑bit core operating up to 16 MHz (80C286‑16).
• Memory Management & Protection Integrated memory management with four‑level memory protection; supports virtual memory and per‑task mapping of up to 1 GByte virtual to 16 MBytes physical address space.
• Operating Modes Supports both real address and protected virtual address modes, enabling compatibility with existing 80C86/80C88 software and source‑level compatibility for protected mode operation.
• Co‑processor Support Compatible with the 80C287 numeric data co‑processor for enhanced math performance.
• Bus Performance High‑bandwidth bus interface capable of 25 MByte/s throughput for efficient system data transfer.
• Low‑Power Static CMOS Design Static CMOS construction with low standby current (ICCSB = 5 mA max) and ICCOP maximum values specified for the 16 MHz variant (260 mA max).
• Package & Mounting 68‑pin PLCC (24.23 × 24.23 mm), J‑lead; surface‑mount package suitable for compact board layouts.
• Operating Conditions & Compliance IO voltage 5 V; operating temperature range 0 °C to +70 °C; consumer qualification and RoHS compliant.

Typical Applications

• Multi‑tasking / Multi‑user Systems Implements operating‑system level task switching, memory protection and virtual memory for systems that require isolated tasks and process management.
• Embedded Consumer Electronics Consumer‑qualified device for embedded designs operating within 0 °C to +70 °C that need a 16‑bit microprocessor with integrated memory management.
• Legacy x86 Software Support Use in applications that benefit from upward compatibility with 80C86/80C88 software through real and protected addressing modes.
• Compute‑Assisted Systems Systems requiring enhanced numeric performance using an 80C287 numeric co‑processor for math acceleration.
