The STM32L051C8T6TR: The internal oscillator, brown-out reset, and power-on reset are on-chip.
The 48-LQFP package with a 7x7 mm body fits compact PCBs and is hand-solderable for prototyping.
The base product number STM32L051 covers a range of density and package variants, which helps with second-sourcing within the family.
The STM32L051C8T6TR is the Tape & Reel packaged variant of the STM32L051C8T6. The silicon and all electrical specifications are identical; the only difference is the shipping medium — TR for automated pick-and-place assembly lines versus the tray or tube of the base part.
Yes. The wide supply range down to 1.65 V, ultra-low-power Cortex-M0+ core, and on-chip brown-out detection make it a natural fit for single-cell battery designs in IoT sensors, portable medical devices, and wireless nodes.
