C8051F369-C-GM

Overview

The C8051F369-C-GM is a mixed-signal ISP Flash MCU from Silicon Labs, featuring a high-speed 8051 core with up to 100 MIPS throughput. It integrates 16 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 and 21 external inputs, a 10-bit current output DAC, and two comparators. Communication interfaces include hardware-enhanced UART, SMBus, and SPI. It operates within a supply voltage range of 2.7–3.6 V at 50 MIPS or 3.0–3.6 V at 100 MIPS, housed in a 28-pin QFN package.

Feature Summary

• High-performance pipelined 8051 core executing 70% of instructions in one or two system clocks
• Integrated 10-bit analog-to-digital converter with built-in temperature sensor and programmable window detector
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators
• Flexible clocking system with internal oscillators and phase-locked loop for power-saving mode switching

Applications

• Industrial control systems requiring mixed-signal processing
• Battery-powered devices utilizing low-power suspend and shutdown modes
• Data acquisition systems leveraging the high-speed ADC and comparators
• Embedded applications needing in-system programming capabilities

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific revision level matches project requirements. Check for end-of-life status as this family may be marked not recommended for new designs. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the 28-pin QFN package dimensions align with the printed circuit board layout specifications.

Selection Notes

Select this model when 16 kB of Flash memory suffices for the application code, distinguishing it from the 32 kB variants in the same family. The 28-pin QFN package is suitable for space-constrained designs compared to larger TQFP or LQFP options. Consider the 100 MIPS performance capability if real-time processing demands exceed standard 8051 speeds. Verify that the integrated analog peripherals meet the signal conditioning requirements before choosing over simpler digital-only microcontrollers.

Part Context

This component belongs to the C8051F36x series of mixed-signal microcontrollers produced by Silicon Laboratories. The series is characterized by its fully integrated system-on-chip architecture, combining a fast 8051-compatible processor with extensive analog and digital peripherals. The C8051F369 variant specifically offers reduced Flash capacity compared to other members like the F367, targeting cost-sensitive applications while maintaining high integration levels.
