The 8 KB SRAM limits data buffers — a 1 KB Modbus holding register plus a 2 KB ADC ring buffer leaves about 5 KB for stack and variables. If the application needs larger frame buffers or a TCP/IP stack, step up to the 128 KB Flash / 16 KB SRAM variants in the same package. The 64-TFBGA measures 5x5 mm with 0.5 mm ball pitch. That is a fine-pitch BGA — not a hand-solder package. The board needs a solder-mask-defined pad, via-in-pad for the centre balls, and X-ray inspection after reflow. Moisture sensitivity is MSL 3 per the STM32F1 family default; bake the trays at 125°C for 48 hours if the sealed bag has been open longer than the floor-life window. The 64-pin LQFP sibling (STM32F100R8T6) is a drop-in alternative for designs that prefer a perimeter-lead package. The base product number STM32F100 covers multiple Flash and RAM density options in the same 64-TFBGA footprint, so a firmware-only migration to a higher-density variant is possible without a board spin.","metaTitle":"STM32F100R8H6B ARM Cortex-M3 MCU, 24 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F100R8H6B 32-bit ARM Cortex-M3 MCU with 24 MHz core, 64 KB Flash, 8 KB SRAM, 51 I/O, industrial temp -40°C to 85°C, 64-TFBGA.","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":"8K 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-TFBGA","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":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-TFBGA (5x5)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bce8111c76ae6a908001d11363aee0ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F100R8H6B/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F100R8H6B and STM32F100R8H6BTR?","answer":"The STM32F100R8H6B ships in tray packaging; the STM32F100R8H6BTR is the tape-and-reel variant.
