ARM Cortex-M3 at 24 MHz — industrial control workhorse
48-LQFP package — board footprint and routing
Housed in a 48-LQFP (7x7 mm) surface-mount package, the STM32F100CBT7B offers 37 I/O lines.
Active lifecycle — stable supply for BOM continuity
The STM32F100CBT7B carries an active lifecycle status from STMicroelectronics.
Peripheral set and connectivity
On-chip peripherals include DMA, a power-on reset (POR), a power-down reset (PDR), a programmable voltage detector (PVD), PWM timers, a temperature sensor, and a watchdog timer. Connectivity interfaces cover I²C, IrDA, LINbus, SPI, and UART/USART — enough for sensor buses, serial displays, and LIN-based automotive networks.
