SB80L188EC16

The SB80L188EC16 is a single‑core 80C186 microprocessor from Intel's i80188 series, featuring a 16‑bit architecture and a 16 MHz operating frequency. Designed for embedded and commercial applications, this surface‑mount MPU integrates support for DRAM control and DMA to address common embedded system requirements.

With 3 V I/O signaling, support for an external 80187 floating‑point coprocessor, and RoHS compliance, the SB80L188EC16 targets embedded designs that require a compact, standards‑oriented 16‑bit processor solution in a 100‑pin SQFP package.

Key Features

• Core 80C186 single 16‑bit core running at 16 MHz for deterministic, low‑complexity embedded processing.
• Memory and DMA Integrated DRAM controller compatibility and DMA interface support to streamline memory access and data movement in embedded systems.
• Co‑processor Support External 80187 FPU compatibility allows offloading floating‑point operations to an external coprocessor when needed.
• Power and I/O 3 V I/O voltage level for interfacing with low‑voltage logic domains.
• Package and Mounting Available in a 100‑pin SQFP (surface mount) package for compact board layouts and automated assembly.
• Operating Range and Grade Commercial grade operation with an ambient temperature range of 0 °C to 70 °C.
• Compliance RoHS compliant to meet environmental regulatory requirements for lead‑free assembly.

Typical Applications

• Embedded control systems — Use the 16‑bit 80C186 core and DMA support for deterministic control tasks in commercial embedded equipment.
• Industrial instrumentation — The DRAM controller and external FPU option support applications that require moderate data buffering and optional floating‑point acceleration.
• Communications and networking appliances — Compact 100‑pin SQFP packaging and DMA capabilities help enable data handling in space‑constrained modules.

Unique Advantages

• Proven 80C186 architecture: A single 16‑bit core running at 16 MHz provides predictable performance for legacy and new embedded designs.
• External floating‑point support: Compatibility with the 80187 FPU lets designers add floating‑point acceleration without changing the core MPU choice.
• Memory and data movement integration: DRAM controller compatibility plus DMA support reduce external glue logic and simplify system memory design.
• Compact surface‑mount package: 100‑pin SQFP enables higher‑density PCB layouts and automated assembly processes.
• Commercial temperature and RoHS compliance: Specified 0 °C to 70 °C operating range and RoHS compliance align with standard commercial embedded deployment requirements.
• Low‑voltage I/O: 3 V I/O signaling supports interfacing with contemporary low‑voltage peripherals and logic families.
