The distinguishing feature here is the package: 64-TFBGA. That is a fine-pitch ball-grid array, not the more common LQFP-64. The BGA saves board area — the balls sit under the body — but it demands a multi-layer PCB with micro-vias or blind vias to route the signals out. If your production line is set up for QFP packages only, this package adds process cost. ## 24 MHz core and 128 KB Flash — sizing the firmware and throughput budget The 24 MHz ARM Cortex-M3 core delivers about 30 DMIPS — enough for real-time control loops running at a few kilohertz, Modbus or CAN node processing, and basic sensor fusion. The 128 KB Flash is the hard firmware-size ceiling; a design that compiles to 90 KB today leaves 38 KB for future field updates over UART or SPI. The 8K x 8 SRAM is tight for buffering — a 4 KB DMA buffer for an ADC scan sequence consumes half of it, so memory-conscious coding is required. The integrated 12-bit ADC has 16 channels, and the dual 12-bit DAC covers analog output needs. DMA offloads peripheral transfers from the core. The serial interface set — I²C, SPI, UART/USART, plus IrDA and LIN — covers most industrial and appliance communication requirements. The internal oscillator and power-on reset (POR/PDR) reduce external BOM count. STMicroelectronics lists the STM32F100RBH6BTR as Active. For new designs, the entire STM32F100 value line shares the same Cortex-M3 core and peripheral IP, so a pin-compatible migration to a larger Flash or RAM variant within the family is possible without a board respin — as long as the package stays the same.","metaTitle":"ST STM32F100RBH6BTR ARM Cortex-M3 MCU, 24 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32F100RBH6BTR 32-bit ARM Cortex-M3 MCU at 24 MHz with 128 KB Flash, 8K x 8 RAM, 51 I/O, industrial temp -40°C to 85°C in 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":"Tape & Reel (TR)","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":"128KB (128K 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":"$3.4302","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bce8111c76ae6a908001d11363aee0ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F100RBH6BTR/alternatives.json"},"ai":{"faq":[{"question":"Can STM32F100RBH6BTR be replaced by STM32F100RBT6?","answer":"The STM32F100RBT6 is a close sibling in the same STM32F100 value line. The key difference is the package: the RBH6BTR is in a 64-TFBGA, while the RBT6 typically comes in an LQFP-64. They share the same core, memory density (128 KB Flash, 8K x 8 RAM), and peripheral set, but the package change means a different PCB footprint and assembly process.
