SB80C188EC13

The SB80C188EC13 is a single‑core 80C186 microprocessor from the Intel i80188 series, featuring a 16‑bit core running at 13 MHz. Designed for commercial embedded applications, the device integrates system interfaces and memory controller support to simplify mid‑range embedded designs.

Key on‑chip capabilities include DRAM controller support and DMA interfaces, with external co‑processor support for the 80187 FPU. The part is supplied in a 100‑pin SQFP surface‑mount package and is RoHS compliant.

Key Features

• Core 80C186 16‑bit single core operating at 13 MHz for predictable control and data handling in embedded systems.
• Memory & Controllers Integrated DRAM controller support to streamline system memory interfacing.
• Co‑processor Support External 80187 FPU support enables hardware floating‑point acceleration when required.
• Interfaces Built‑in DMA support for efficient data movement without continuous CPU intervention.
• Power & I/O 5 V I/O signaling compatible with legacy and commercial embedded peripherals.
• Package & Mounting 100‑pin SQFP (100‑BFQFP package case) in a surface‑mount form factor suitable for compact PCB assemblies.
• Operating Range & Grade Commercial grade with an operating temperature range of 0 °C to 70 °C and RoHS compliance for regulatory alignment.

Typical Applications

• Embedded control systems — Suited for mid‑range controllers that benefit from a 16‑bit core, DMA, and DRAM interface for responsive control and data buffering.
• Industrial automation (commercial) — Applicable to commercial‑grade automation equipment where predictable 13 MHz processing and standard 5 V I/O are required.
• Legacy system maintenance — Useful for replacing or maintaining existing designs that use the i80188 family and require a 100‑pin SQFP footprint.

Unique Advantages

• Single 16‑bit core architecture: Provides deterministic processing suitable for control and real‑time tasks in embedded designs.
• Onboard memory controller support: DRAM controller capability reduces external glue logic and simplifies memory subsystem design.
• External FPU compatibility: Support for the 80187 co‑processor enables optional hardware floating‑point acceleration without changing the CPU core.
• Efficient data movement: DMA interfaces lower CPU overhead for bulk transfers, improving system throughput for data‑intensive routines.
• Commercial grade and RoHS compliant: Meets common commercial environmental ranges (0 °C to 70 °C) and regulatory requirements for lead‑free assemblies.
• Standard SQFP packaging: 100‑pin surface‑mount SQFP simplifies assembly and replaces common package footprints in existing boards.

Why Choose SB80C188EC13?

The SB80C188EC13 positions itself as a practical choice for commercial embedded designs that require a 16‑bit Intel i80188‑series core with integrated memory controller and DMA capabilities. Its support for an external 80187 FPU lets designers scale numeric performance as needed while retaining the same core.

With a 100‑pin SQFP surface‑mount package, 5 V I/O compatibility, and RoHS compliance, this device is suited to stable, long‑life commercial applications and maintenance of legacy i80188‑based platforms.
