SB80C188-12

The SB80C188-12 is a single-core 80C186 microprocessor IC operating at 12 MHz, built on the Am80188 series from Advanced Micro Devices. It provides a 16-bit core with integrated DRAM controller capability and 5 V I/O compatibility for embedded system designs.

Targeted at commercial-grade embedded applications, the SB80C188-12 combines a compact 80‑QFP surface-mount package with a defined operating range and RoHS compliance to support reliable board-level integration.

Key Features

• Core  80C186 single 16-bit core delivering 12 MHz operation for deterministic, low-frequency embedded processing.
• Memory Support  Includes DRAM controller functionality to interface with external dynamic RAM as part of system memory architectures.
• Voltage I/O  5 V I/O voltage compatibility suitable for designs that require standard TTL/CMOS signal levels.
• Package & Mounting  Supplied in an 80‑QFP package for surface-mount PCB assembly and compact board layouts.
• Operating Range  Commercial temperature grade with an operating range of 0°C to 70°C for standard commercial environments.
• Regulatory  RoHS compliant to meet lead‑free manufacturing and environmental requirements.
• Graphics  No graphics acceleration—designed for control and processing tasks rather than graphics workloads.

Typical Applications

• Embedded Control  Use in embedded systems that require a 16-bit processing core at 12 MHz for control, sequencing, or I/O management.
• Memory-Buffered Systems  Suitable for designs that leverage an on-chip DRAM controller to interface with external DRAM for program or data storage.
• Commercial Electronics  Ideal for commercial-grade products that operate within 0°C to 70°C and require 5 V I/O compatibility and surface-mount packaging.
