EE80C186XL20

The EE80C186XL20 is an Intel 80C186XL-series embedded microprocessor configured as a single-core, 16-bit CPU running at 20 MHz. It combines a static, modular 80C186 core with an integrated peripheral set tailored for embedded systems and general-purpose embedded microprocessor applications.

Targeted at embedded designs, this device delivers on-board DMA, timers, interrupt control and DRAM refresh support in a low-power, surface-mount 68-pin PLCC package, providing a compact, RoHS-compliant solution for commercial temperature-range applications.

Key Features

• Core 80C186 modular, fully static CPU core; single-core, 16-bit architecture running at 20 MHz.
• Memory & Bus Direct addressing capability to 1 MByte memory and 64 Kbyte I/O (series-level feature); programmable memory and peripheral chip-select logic and a local bus controller support system integration.
• DMA & Interrupts Integrated DMA support with 2 independent DMA channels and a programmable interrupt controller for deterministic data movement and interrupt handling.
• Timers & DRAM Three programmable 16-bit timers and a dynamic RAM refresh control unit simplify timing and memory maintenance tasks.
• Coprocessor Interface Direct interface to the 80187 math coprocessor (80C186XL series capability) for external floating-point acceleration.
• Power Management Low-power, fully static implementation with a power-save mode to reduce system idle power.
• Package & Mounting 68-pin PLCC (68-LCC J-lead) surface-mount package for compact PCB layouts and established assembly processes.
• Electrical & Environmental 5 V I/O voltage and RoHS compliance; commercial operating temperature range of 0 °C to 70 °C.
• Compatibility Series-level compatibility: object code compatible with 8086/8088 software and includes additional instructions over the 8086/8088 architectures.

Typical Applications

• Embedded controllers — Compact control applications that require an integrated CPU with on-chip DMA, timers and interrupt management.
• Industrial automation (commercial range) — Control and I/O handling for commercial-temperature automated equipment where a 16-bit embedded processor is suitable.
• Legacy system integration — Reuse of 8086/8088-compatible codebases and support for external 80187 coprocessors in systems undergoing refresh or maintenance.

Unique Advantages

• Highly integrated peripheral set: On-chip DMA channels, programmable interrupt controller, timers and DRAM refresh reduce external BOM and simplify board-level design.
• Low-power, static core: Fully static implementation with a power-save mode supports lower-power operation and straightforward clock control.
• External math coprocessor support: Direct interface to the 80187 coprocessor enables optional floating-point acceleration without redesigning the CPU subsystem.
• Proven code compatibility: Object code compatibility with 8086/8088 simplifies code migration and preserves existing software investments.
• Compact, surface-mount package: 68-pin PLCC with J-leads provides a reliable, assembly-friendly footprint for space-constrained PCBs.
• Regulatory and temperature suitability: RoHS compliance and commercial operating range (0 °C to 70 °C) support standard embedded product requirements.
