Product details

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 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.

Frequently asked questions

What is the difference between STM32L053C6T7 and STM32L053C6T6?

The suffix 'T7' versus 'T6' in the STM32L053C6 family typically indicates a different temperature grade or packaging variant. Confirm the exact ordering code against your temperature requirements before substituting.
