C8051F366-C-GQ

Overview

The C8051F366-C-GQ is a mixed-signal ISP Flash MCU from the Silicon Labs C8051F36x family, featuring a high-speed 8051-compatible CIP-51 core with up to 100 MIPS throughput. It integrates 32 kB of in-system programmable Flash memory 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 multiple digital peripherals including UART, SMBus, and SPI. It operates on a 2.7–3.6 V supply and is housed in a 32-pin LQFP package.

Feature Summary

• High-performance CIP-51 core executing 70% of instructions in one or two system clocks
• Integrated 10-bit ADC with programmable window detector and temperature sensor
• On-chip debug circuitry enabling full-speed non-intrusive in-system debugging
• Flexible clocking system with internal oscillators and phase-locked loop

Applications

• Industrial control systems requiring mixed-signal processing
• Embedded applications needing precise analog-to-digital conversion
• Battery-powered devices utilizing low-power sleep modes
• Communication interfaces using hardware-enhanced serial ports

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as per latest datasheet revisions. Check for Not Recommended for New Designs (NRND) status implications for long-term supply. Ensure packaging matches specified LQFP-32 dimensions. Validate operating temperature range suitability for target environment.

Selection Notes

Select this model when 32 kB Flash and 1280 bytes RAM are sufficient. Choose if 21 ADC channels and 10-bit resolution meet signal acquisition needs. Opt for LQFP-32 package for space-constrained PCB layouts. Consider NRND status for new product introductions requiring long lifecycle support.
