That is fine for a UART-to-SPI bridge, a PWM fan controller, a CAN gateway running at 125 kbps, or a temperature-logger polling a sensor every 100 ms. If your application needs floating-point or a 72 MHz bus for a display frame buffer, this part is not the fit — but for the majority of 8-bit upgrades and low-bandwidth control loops, 24 MHz with zero-wait-state Flash access is enough headroom. ## 128 KB Flash and 8K x 8 RAM — firmware and data budget 128 KB of Flash is the mid-density option in the STM32F100 line. A typical FreeRTOS application with a TCP/IP stack and a command-line interface fits in about 60 KB to 80 KB, leaving room for a bootloader and OTA staging. The 8K x 8 SRAM is tight — budget 4 KB for the stack and heap, 2 KB for DMA buffers, and the rest for global variables. If your design queues Ethernet frames or stores a large lookup table, the RAM will be the constraint before Flash. ## Industrial temperature grade and on-chip peripherals The integrated DMA, POR, PVD, and windowed watchdog reduce external BOM count — no separate reset supervisor or brown-out detector needed. ## Package and footprint: 100-LQFP (14x14) The 100-LQFP with 0.5 mm pitch and a 14x14 mm body is a common footprint for 4-layer boards. The exposed pad is not present on this package variant, so thermal dissipation is through the leads — keep the ambient airflow or derate if the part runs continuous PWM at 85°C.","metaTitle":"STM32F100VBT6BTR STMicroelectronics MCU, 24 MHz","metaDescription":"STM32F100VBT6BTR is an active ARM Cortex-M3 MCU from ST with 24 MHz core, 128 KB Flash, 8K x 8 RAM, 80 I/O, -40 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":"Tape & Reel (TR) Cut Tape (CT)","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":"80","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-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":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4400","priceTiers":[{"qty":1,"price":"$6.44000","currency":"USD"},{"qty":10,"price":"$5.81400","currency":"USD"},{"qty":25,"price":"$5.54320","currency":"USD"},{"qty":100,"price":"$4.81320","currency":"USD"},{"qty":250,"price":"$4.59692","currency":"USD"},{"qty":500,"price":"$4.19132","currency":"USD"},{"qty":1000,"price":"$3.65050","currency":"USD"},{"qty":2000,"price":"$3.51530","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bce8111c76ae6a908001d11363aee0ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F100VBT6BTR/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F100VBT6BTR have built-in flash memory?","answer":"Yes, it has 128 KB of on-chip Flash program memory (128K x 8), plus 8K x 8 of SRAM.
