C8051F302-GM

Overview

The C8051F302-GM is an 8-bit mixed-signal ISP Flash MCU from Silicon Labs, featuring a high-speed CIP-51 core operating at up to 25 MHz with 25 MIPS throughput. It integrates 8 kB of Flash memory and 256 bytes of internal data RAM. The device includes an 8-bit ADC supporting up to 500 ksps with eight external inputs and programmable amplifier gains. Supply voltage ranges from 2.7 V to 3.6 V, with typical operating current of 6.6 mA at 25 MHz and 14 μA at 32 kHz. It operates within a temperature range of –40 °C to +85 °C and is housed in an 11-pin QFN package measuring 3x3 mm.

Feature Summary

• Integrated on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Pipelined instruction architecture that executes the majority of instructions in one or two system clocks for improved throughput.
• Programmable digital I/O crossbar allowing flexible mapping of internal digital resources to physical pins via software configuration.

Applications

• Industrial control systems
• Consumer electronics
• Motor control applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package type. Check for RoHS compliance status as indicated in official documentation. Ensure the revision level aligns with design requirements. Validate supply chain sources against Silicon Labs' official partner list.

Selection Notes

Evaluate the 8-bit ADC resolution and sampling rate against signal processing needs. Consider the 256-byte RAM limit for complex algorithm implementation. Assess the 8 kB Flash capacity for firmware size requirements. Verify compatibility with existing development tools like Simplicity Studio. Review power consumption profiles for battery-operated designs.

Part Context

This microcontroller belongs to the C8051F30x family of mixed-signal ISPs. It shares architectural similarities with the C8051F300, differing primarily in peripheral configurations such as the inclusion of the 8-bit ADC. The family utilizes the CIP-51 core and offers various package options including QFN and SOIC.
