Memory and peripheral budget
The STM32F101V8T6: 64 KB Flash and 10 KB SRAM limit firmware to a modest application. On-chip peripherals include DMA, a temperature sensor, PWM timers, and a watchdog, plus I²C, SPI, UART/USART, LIN, and IrDA. A 12-bit ADC with 16 multiplexed channels covers analog sensing.
Supply range and clocking
An internal oscillator is available, so a minimal system can start up without an external crystal — useful for cost-sensitive or space-constrained boards.
