Brown-out detect, POR, PWM, a watchdog timer, and DMA round out the on-chip peripherals — no external supervisor or watchdog IC needed for many designs.
Housed in a 48-pin UFQFPN with an exposed pad (7x7 mm body), this package is a surface-mount fine-pitch QFN.
ST lists the STM8L151C6U6TR as Active.
The difference is the shipping medium: the STM8L151C6U6 is the tray/tube variant, while the STM8L151C6U6TR is the Tape & Reel version intended for automated pick-and-place assembly. The silicon, package, and all electrical ratings are identical.
ST's ST-Link/V2 or ST-Link/V3 debug probes, along with the ST Visual Programmer (STVP) or the STM8CubeProgrammer software, support the STM8 core via SWIM (Single Wire Interface Module). Third-party tools from IAR and Cosmic also compile for the STM8 architecture.
