C8051F365-GM

Overview

The C8051F365-C-GMR is an 8-bit mixed-signal microcontroller from Silicon Labs, featuring a high-speed 8051 core with up to 100 MIPS throughput. It includes 32 kB of in-system programmable Flash memory and 1280 bytes of internal data RAM. The device integrates a 10-bit ADC supporting up to 200 ksps, a 10-bit current output DAC, two comparators, and a built-in temperature sensor. Digital peripherals include hardware-enhanced UART, SMBus, SPI, four 16-bit timers, and a 16-bit PCA. It operates on a 2.7–3.6 V supply and is housed in a QFN-28 package.

Procurement Notes

Verify the specific suffix 'C' against the official datasheet to confirm temperature range and package details. Confirm that the component status is acceptable for your design lifecycle, as this family may be marked as Not Recommended for New Designs. Ensure compatibility with existing development tools and verify pinout alignment if replacing older revisions.

Selection Notes

Select this model when a complete system-on-a-chip solution is required with integrated analog peripherals. It is suitable for applications needing high-speed processing alongside precise signal acquisition. Consider the QFN-28 package constraints for PCB layout. Evaluate power consumption requirements against the available suspend and shutdown modes.

Part Context

This part belongs to the C8051F36x family of mixed-signal ISP Flash MCUs. The family shares a common architecture but varies in memory size, package type, and peripheral availability. The C8051F365 specifically utilizes the 28-pin QFN package and includes the full analog suite found in the higher-end variants of this series.

Replacement Considerations

Check for direct substitutes within the C8051F36x family such as C8051F362 or C8051F367, ensuring pin compatibility and feature parity. Verify if newer Silicon Labs MCU families offer equivalent performance with improved availability.
