S80L186EB16

The S80L186EB16 is an Intel i80186-series microprocessor in a single-core 16-bit implementation running at 16 MHz. It is supplied in a surface-mount 80-pin PQFP (14×20) package and targets embedded microprocessor applications that require on-chip DRAM controller support and DMA interfaces.

Designed as a commercial-grade, RoHS-compliant device, the S80L186EB16 supports an external 80187 floating‑point coprocessor and operates across a 0 °C to 70 °C range with a 3 V I/O voltage.

Key Features

• Core & Performance — 80C186 core, single 16‑bit processor running at 16 MHz, suitable for embedded control and system management tasks.
• Memory & System Integration — Built-in DRAM controller to simplify external memory interfacing and reduce system design complexity.
• Arithmetic Expansion — Support for an external 80187 FPU (floating‑point coprocessor) for enhanced numeric processing when required.
• Data Transfer — DMA interface included to enable efficient peripheral-to-memory transfers without continuous CPU intervention.
• Power & I/O — 3 V I/O voltage specification suitable for compatible embedded system designs.
• Package & Mounting — Surface-mount 80‑PQFP (14×20) supplier device package with package case listed as 80‑BQFP for compact PCB integration.
• Operating Range & Grade — Commercial grade device rated for operation from 0 °C to 70 °C and RoHS compliant.

Typical Applications

• Embedded Controllers — Use the 16‑bit 80C186 core and integrated DRAM controller for general-purpose embedded control, I/O management, and system housekeeping.
• Industrial Automation — Leverage the DMA interface and external FPU support for control tasks and numeric processing in industrial equipment within commercial temperature ranges.
• Legacy System Maintenance — Suitable for refurbishment or continued production of systems using the i80186 architecture where a compatible surface‑mount MPU is required.

Unique Advantages

• Compact surface‑mount package — 80‑PQFP (14×20) package reduces board footprint for space-constrained embedded designs.
• Integrated memory controller — On-chip DRAM controller reduces external logic and BOM for memory subsystem implementation.
• External FPU support — Compatibility with the 80187 coprocessor allows designers to add floating‑point capability when needed without changing the MPU.
• Built-in DMA — Hardware DMA support helps offload routine data transfers from the CPU, improving system efficiency.
• Commercial-grade, RoHS compliant — Meets commercial temperature requirements and environmental compliance for a wide range of embedded products.
