32 MHz ARM Cortex-M0+ — what the core delivers for low-power designs
The STMicroelectronics STM32L053C6T7 is a 32-bit single-core MCU built around the ARM Cortex-M0+ processor, running at 32 MHz.
Peripheral set and I/O — what is wired in
The part integrates a 10-channel 12-bit ADC and a single 12-bit DAC, so analog sensor readout and small-signal output are handled without an external converter. The 37 general-purpose I/Os in the 48-LQFP package give headroom for a keypad, LEDs, and a few external interrupts without needing a port expander.
The 48-LQFP (7x7 mm) package is a common footprint that reflows on standard FR-4 with no special stencil requirements.
