C8051F132

Overview

The C8051F132-GQR is an 8-bit microcontroller from Silicon Labs, featuring a high-speed 8051 core with up to 100 MIPS throughput. It includes 64 kB of in-system programmable Flash memory and 8.448 kB of internal data RAM. The device integrates a 10-bit SAR ADC with programmable throughput up to 100 ksps and two analog comparators. Operating at frequencies up to 100 MHz, it supports a supply voltage range of 3.0 V to 3.6 V for full performance. Packaged in a 100-pin TQFP, it operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Integrated on-chip JTAG debug circuitry enables full-speed, non-intrusive in-circuit debugging without external emulators.
• Features a pipelined instruction architecture that executes the majority of the instruction set in one or two system clocks.
• Includes a flexible Phase-Locked Loop (PLL) technology for generating high-speed system clock frequencies.

Applications

• In-system programming applications requiring direct code updates via Flash memory.
• High-performance industrial control systems utilizing fast 8051 processing.
• Data acquisition systems leveraging integrated analog peripherals like ADCs and comparators.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Confirm component availability status as some variants may be subject to end-of-life notices. Ensure compatibility with existing PCB footprints for the 100-pin TQFP configuration before finalizing procurement decisions.
