If the firmware needs a USB stack or a GUI, this part runs out of room. The 37 I/O in the 48-LQFP package leave room for a keypad, LEDs, and a few external peripherals. It is ROHS3 compliant. For dual-sourcing or a drop-in with more flash, the STM32L151CBU6A (also Cortex-M3, 32 MHz, 128 KB Flash, same 48-pin footprint) is a functional alternative, though it adds USB and capacitive sensing — check the firmware and peripheral map before swapping.","metaTitle":"STM32F100C4T6BTR ARM Cortex-M3 MCU, 24 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32F100C4T6BTR 32-bit ARM Cortex-M3 MCU, 24 MHz core, 16 KB Flash, 4 KB SRAM, 10x12-bit ADC, 2x12-bit DAC, 37 I/O, -40 to 85°C, 48-LQFP.","metaKeywords":null},"attributes":{"series":"STM32F1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"24MHz","Series":"STM32F1","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, PDR, POR, PVD, PWM, Temp Sensor, WDT","Connectivity":"I2C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"37","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F100","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3500","priceTiers":[{"qty":1,"price":"$4.35000","currency":"USD"},{"qty":10,"price":"$3.90300","currency":"USD"},{"qty":25,"price":"$3.69000","currency":"USD"},{"qty":100,"price":"$3.19810","currency":"USD"},{"qty":250,"price":"$3.03408","currency":"USD"},{"qty":500,"price":"$2.72246","currency":"USD"},{"qty":1000,"price":"$2.29605","currency":"USD"},{"qty":2400,"price":"$2.18125","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bce8111c76ae6a908001d11363aee0ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F100C4T6BTR/alternatives.json"},"ai":{"faq":[{"question":"What is the core of STM32F100C4T6BTR?","answer":"The core is a 32-bit ARM Cortex-M3 running at 24 MHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F100C4T6BTR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F100C4T6BTR when reusing this data.
