S80C186EB25

The S80C186EB25 is a commercial-grade microprocessor from Intel based on the 80C186 core. It is a single-core, 16-bit MPU operating at 25 MHz and designed for embedded applications requiring a 5 V supply and a surface-mount 80-pin PQFP package.

Built for embedded and commercial systems, the device provides on-chip DRAM controller support, DMA interfaces, and external 80187 floating-point co-processor support to address control and data handling needs in a compact package.

Key Features

• Core & Performance 80C186 single core, 16-bit architecture running at 25 MHz for deterministic, low-complexity processing tasks.
• Memory & DMA Includes DRAM controller support and DMA interfaces to streamline data transfers and memory access in embedded designs.
• Co-processor Support External 80187 FPU support enables optional floating-point acceleration when needed by the application.
• Power Operates from a 5 V I/O voltage, matching legacy and commercial embedded power rails.
• Package & Mounting 80-lead PQFP (14 × 20 mm) surface-mount package suitable for compact PCB layouts and automated assembly.
• Operating Range & Grade Commercial-grade device with an operating temperature range of 0 °C to 70 °C.
• Additional Interfaces Integrated DMA support to offload data movement and improve throughput for peripheral and memory operations.
• Compliance RoHS-compliant for environmental and manufacturing process requirements.

Typical Applications

• Embedded control systems — Use as a 16-bit control processor in compact embedded devices where deterministic, single-core performance at 25 MHz is sufficient.
• Commercial electronics — Suitable for consumer or commercial devices that require a surface-mount, 5 V microprocessor with DRAM and DMA support.
• Legacy platform maintenance — Drop-in-compatible option for maintaining or refurbishing systems built around the i80186 family.
• Peripheral controllers — Handles peripheral interfacing and data movement tasks using on-chip DRAM controller and DMA capabilities.

Unique Advantages

• Well-defined 16-bit architecture — The 80C186 core delivers straightforward processing for control-oriented embedded designs.
• On-chip DRAM controller and DMA — Reduces external logic and simplifies board-level memory and data-transfer design.
• External FPU option — Support for the 80187 co-processor lets designers add floating-point performance only when required.
• Compact surface-mount package — 80-PQFP (14×20 mm) package enables high-density PCB layouts and automated assembly workflows.
• Commercial temperature and RoHS compliance — Matches common commercial deployment environments while meeting environmental manufacturing requirements.
