N80C186-12/TR

The N80C186-12/TR is a single-core 16-bit microprocessor from the Am80186 family by Advanced Micro Devices. Operating at 12 MHz with a 5 V I/O domain and DRAM controller support, it is designed for embedded, commercial-grade applications requiring proven 16-bit processing and standard surface-mount packaging.

Packaged in a 68-lead LCC (J-lead) surface-mount case and rated for 0 °C to 70 °C operation, this MPU suits embedded system designs where compatibility with 5 V systems, DRAM interfacing, and compact board-level integration are required.

Key Features

• Core and Architecture  The 80C186 core provides a single 16-bit processing engine running at 12 MHz for deterministic embedded control tasks.
• Memory Interface  DRAM controller support enables direct interfacing to dynamic RAM memory for systems that require external volatile memory.
• Voltage and I/O  5 V I/O voltage compatibility for integration into existing 5 V embedded platforms.
• Package and Mounting  Supplied in a 68-LCC (J-Lead) package designed for surface-mount assembly, offering a compact footprint for PCB layouts.
• Operating Range and Grade  Commercial-grade device with an operating temperature range of 0 °C to 70 °C suitable for standard indoor and controlled-environment equipment.
• Compliance  RoHS compliant, meeting common environmental requirements for electronic assemblies.
• Graphics and Acceleration  No graphics acceleration, focusing the device on control and processing roles rather than graphics tasks.

Typical Applications

• Embedded Control Systems  A compact 16-bit MPU for control logic, sequencing, and supervisory functions in embedded devices.
• Industrial and Commercial Equipment  Suitable for commercial-grade equipment that requires deterministic processing within a 0 °C to 70 °C operating window.
• Legacy System Maintenance  Useful for repair or maintenance of existing systems designed around the Am80186 family and 5 V platforms.

Unique Advantages

• Proven 16-bit Architecture:  The 80C186 core provides established 16-bit processing capability for control-oriented designs.
• DRAM Controller Support:  Built-in DRAM controller support simplifies memory interfacing and reduces external memory logic complexity.
• 5 V System Compatibility:  Native 5 V I/O reduces the need for level translation in legacy or established 5 V systems.
• Surface-Mount 68-LCC Package:  The 68-LCC (J-lead) surface-mount package enables compact PCB integration and standard SMT assembly.
• Commercial Operating Range:  Rated 0 °C to 70 °C and commercial grade for mainstream indoor electronic products.
• RoHS Compliant:  Conforms to RoHS environmental requirements for modern electronic assemblies.
