The 64-TFBGA package is the main differentiator from the more common LQFP variants. This is not a hand-reworkable package; if you need to spin a prototype on a two-layer board with a hot-air station, the LQFP-48 or LQFP-64 sibling is the practical choice. ## 24 MHz and 32 KB Flash — sizing the firmware budget At 24 MHz the Cortex-M3 delivers enough throughput for 10–50 kHz control loops, UART polling at 115.2 kbaud, and moderate sensor fusion. The 32 KB Flash fills firmware for a single-purpose controller — a fan speed regulator, a keypad decoder, a simple CAN gateway — but leaves little room for a full RTOS plus application stack. The 4 KB SRAM (organized as 4K x 8) similarly constrains data buffers; a 1 KB Ethernet or USB descriptor would consume a quarter of it, so this part is best matched to I²C, SPI, and UART-based designs. ST continues to manufacture the STM32F1 Value Line, and there is no announced EOL or last-time-buy window.","metaTitle":"STM32F100R6H6B STM32 Value Line MCU, 24 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F100R6H6B ARM Cortex-M3 MCU, 24 MHz, 32 KB Flash, 4 KB RAM, 64-TFBGA.
