The wide supply range also means you can run it from a 3.6V Li-ion cell without an LDO, saving a regulator and a capacitor on the BOM. ## On-chip analog and connectivity — what the peripherals cover 13-channel 12-bit ADC and single 12-bit DAC. The 39 GPIOs in the 48-LQFP package leave enough pins for a parallel LCD interface or a bank of opto-isolated inputs while still routing the serial peripherals. Peripherals include DMA, I²S, POR, PWM, and WDT — the DMA offloads ADC results and UART data without core stalls, and the PWM timers are suitable for driving MOSFETs in a buck converter or BLDC commutation at up to 48 MHz timer clock. The base product number STM32F051 has been in volume production for years, meaning the supply chain is mature and the die is well-characterized across temperature corners. Submit an RFQ for your target volume and we will confirm lead time and pricing against the current market.","metaTitle":"STM32F051C8T7TR STM32F0 ARM Cortex-M0 MCU, 48 MHz","metaDescription":"STMicroelectronics STM32F051C8T7TR 32-bit MCU: ARM Cortex-M0 at 48 MHz, 64KB Flash, 8K x 8 RAM, 48-LQFP, -40°C to 105°C, 2V-3.6V supply.

The 'TR' suffix denotes Tape & Reel packaging. Electrically and functionally they are identical, so the T7TR can replace the T6 in the same PCB footprint as long as the application's temperature requirement is met."},{"question":"What is the maximum operating frequency of STM32F051C8T7TR?","answer":"The maximum core clock speed is 48 MHz. At this frequency the flash requires one wait state for zero-wait execution; the STM32F0 prefetch buffer helps maintain single-cycle throughput for sequential code."},{"question":"How much flash memory and RAM does STM32F051C8T7TR have?","answer":"It has 64 KB of Flash (organized as 64K x 8) and 8K x 8 of SRAM. The 64 KB Flash is sufficient for a full RTOS kernel, a communication stack (e.g., Modbus or CANopen), and application code. The 8 KB RAM handles stack, heap, and DMA buffers — budget around 2 KB for the RTOS and stack, leaving 6 KB for data."},{"question":"When sourcing STM32F051C8T7TR, what is the closest functional second-source?","answer":"The STM32L151CBU6A is a Cortex-M3 alternative running at 32 MHz with 1.8V supply and USB connectivity, but it is not pin-compatible (different package and supply voltage). For a direct pin-compatible second source, stay within the STM32F051Cx family — the STM32F051C8T6 (same die, narrower temp range) or the STM32F051C4T6 (16 KB Flash, smaller memory) share the same 48-LQFP footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F051C8T7TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F051C8T7TR when reusing this data.
