STM32C051 in STM32 Family
The STM32C051 sub-family from STMicroelectronics represents a cost-effective 32-bit entry point into the STM32 ecosystem, powered by the efficient ARM Cortex-M0+ core. Designed to bridge the gap between 8-bit/16-bit legacy microcontrollers and high-performance 32-bit units, these MCUs operate at 48MHz. They provide a streamlined peripheral set and small footprint, making them ideal for high-volume consumer and industrial applications where board space and bill-of-materials costs are critical constraints.

| Part Number | I/O Pins | Package | ADC/DAC | Stock |
|---|---|---|---|---|
| STM32C051K8T6 (STMicroelectronics) | 30 | LQFP-32 | A/D 20x12b SAR | 4,601 |
| STM32C051G8U6 (STMicroelectronics) | 26 | UFQFN-28 | A/D 19x12b SAR | 11,579 |
Variants within the STM32C051 sub-family primarily differ in package type and pin count, ranging from compact 20-pin TSSOP to 48-pin LQFP configurations. While most members offer 64 KB of Flash memory, some versions are tailored with smaller memory footprints to further reduce costs. Operating temperature grades also vary, with options for standard industrial ranges or extended ranges suitable for more demanding thermal environments found in lighting or power supplies.
