A8028610

The A8028610 is an Intel 80286-series microprocessor implemented as an iAPX86 core running at 10 MHz. Designed for embedded applications, it provides a single-core 80286 architecture with support for external 80287 floating-point co‑processing and DRAM memory controllers.

Its commercial-grade specification, 5 V I/O voltage and 68‑CPGA through-hole package make it suitable for systems that require a classic 80286 processing element with clear integration points for memory and math acceleration.

Key Features

• Core  80286 core processor providing a single-core architecture suited to legacy and embedded 80286-based designs.
• Clock Speed  10 MHz operating frequency for applications designed around this clock domain.
• Memory Support  Designed to work with DRAM memory controllers as specified in the product data.
• Co‑processing  Supports an external 80287 FPU for hardware floating-point acceleration where required.
• Power and I/O  5 V I/O voltage compatibility for systems using standard 5 V signaling.
• Package and Mounting  68‑CPGA package supplied for through‑hole mounting to simplify board assembly and mechanical retention.
• Operating Range  Commercial temperature grade with an operating range of 0 °C to 85 °C.
• Regulatory  RoHS compliant.
• Graphics  No integrated graphics acceleration.

Typical Applications

• Embedded Control Systems  Use as the primary MPU in embedded controllers where an 80286 instruction set and 10 MHz clocking meet system requirements.
• Industrial Automation  Deploy in commercial-grade automation equipment operating within 0 °C to 85 °C that leverage external DRAM and optional 80287 co‑processing.
• Legacy System Maintenance  Suitable for repair or maintenance of existing systems designed around the 80286 architecture and 68‑CPGA mounting.

Unique Advantages
