The STM32F100R4T6B integrates a 12-bit ADC with 16 multiplexed channels and two 12-bit DACs, enabling direct sensor readback and analog output without an external converter. The DMA controller offloads the CPU for peripheral-to-memory transfers, which matters when the 24 MHz core is handling real-time control loops.","metaTitle":"STM32F100R4T6B STMicroelectronics MCU 32-bit ARM Cortex-M3","metaDescription":"STM32F100R4T6B 32-bit ARM Cortex-M3 MCU, 24 MHz, 16 KB Flash, 4 KB RAM, 51 I/O, 64-LQFP, -40°C to 85°C.","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":"Tray","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":"51","Core Processor":"ARM® Cortex®-M3","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; 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)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.1200","priceTiers":[{"qty":1,"price":"$5.12000","currency":"USD"},{"qty":10,"price":"$4.59600","currency":"USD"},{"qty":25,"price":"$4.34480","currency":"USD"},{"qty":160,"price":"$3.76550","currency":"USD"},{"qty":320,"price":"$3.57238","currency":"USD"},{"qty":480,"price":"$3.20550","currency":"USD"},{"qty":960,"price":"$2.70343","currency":"USD"},{"qty":2400,"price":"$2.56825","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bce8111c76ae6a908001d11363aee0ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F100R4T6B/alternatives.json"},"ai":{"faq":[{"question":"Is the STM32F100R4T6B obsolete or still active?","answer":"It is RoHS3 compliant and can be used in new production designs without immediate obsolescence risk."},{"question":"Does the STM32F100R4T6B have a pin-compatible replacement?","answer":"The STM32L151CBU6A is a functional peer also based on the ARM Cortex-M3 core, but it runs at 32 MHz, includes USB, and operates down to 1.8 V.
