24 MHz Cortex-M3 value-line — what the ceiling buys
That 24 MHz ceiling is deliberate: it places this part in the cost-optimised tier for control-loop and sensor-fusion tasks where the 72 MHz F103's extra headroom would add BOM cost without benefit.
Peripherals that shrink the BOM
The peripheral set includes DMA, POR, PDR, PVD, a temperature sensor, and a watchdog timer, covering the usual supervision and housekeeping without extra ICs.
The base product number STM32F100 covers a density range; the RDT6 variant with 384 KB Flash and the BTR suffix (Tape & Reel) is a standard catalog item.
