The 4 KB RAM (organized as 4K x 8) handles a modest call stack, a few hundred bytes of global data, and a UART or SPI buffer. If your application needs over-the-air update staging or a large lookup table, step up to the 32 KB or 64 KB Flash siblings in the same 48-LQFP footprint. ## 48-LQFP — layout and supply rails The 37 I/O lines include most peripheral signals; check the alternate-function mapping in the datasheet to avoid pin conflicts. Decouple with a 100 nF ceramic per VDD pair plus a 4.7 µF bulk cap.","metaTitle":"STM32F100C4T7B ARM Cortex-M3 MCU, 24 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32F100C4T7B 32-bit ARM Cortex-M3 MCU, 24 MHz core, 16 KB Flash, 4 KB RAM, 48-LQFP, -40 to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"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~105°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.0600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bce8111c76ae6a908001d11363aee0ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F100C4T7B/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32F100C4T7B in this component family?","answer":"For higher Flash density in the same 48-LQFP footprint, consider the STM32F100C6 (32 KB Flash) or STM32F100C8 (64 KB Flash) — verify pin compatibility against the datasheet."},{"question":"What is STM32F100C4T7B's listed speed?","answer":"The core runs at 24 MHz, which is the maximum clock frequency for this value-line Cortex-M3.
