C8051F366-GQ

Overview

The C8051F366-GQ is a mixed-signal ISP Flash MCU from Silicon Labs, featuring an 8051-compatible core with up to 100 MIPS throughput. It integrates 32 kB of in-system programmable Flash and 1280 bytes of internal data RAM. The device includes a 10-bit ADC supporting up to 200 ksps with 21 external inputs, a 10-bit current output DAC, two comparators, and a built-in temperature sensor. Digital peripherals include hardware UART, SMBus, SPI, four 16-bit timers, and a PCA with six capture/compare modules. It operates on a 2.7–3.6 V supply within a –40 to +85 °C range.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific package type matches design requirements. Check for end-of-life status as indicated in documentation. Ensure environmental compliance aligns with project specifications. Validate pinout compatibility during integration planning.

Selection Notes

Evaluate memory requirements against the 32 kB Flash and 1280 bytes RAM capacity. Consider analog peripheral needs such as ADC resolution and input count. Assess digital interface requirements for UART, SPI, or SMBus connectivity. Verify voltage supply constraints fit the 2.7–3.6 V operating range. Review package options to ensure physical fitment on the target PCB.

Part Context
