Product details

The STM32L053C8T7 is an ultra-low-power 32-bit MCU built around the ARM Cortex-M0+ core, clocked at 32 MHz. On-chip peripherals include a USB 2.0 full-speed interface, an I2S audio bus, and a segment LCD driver — features that consolidate BOM count in portable instruments, smart meters, and IoT edge nodes.

The 48-LQFP package (7x7 mm body) is a common footprint for mid-density MCUs, and the 37 available I/O pins leave room for a parallel LCD bus, keypad matrix, and sensor interfaces alongside the USB and I2S blocks.

Frequently asked questions

What are the key differences between STM32L053C8T7 and STM32L053C8T6?

The STM32L053C8T7 and STM32L053C8T6 share the same die, Flash and RAM sizes, and peripheral set. For designs that must operate above 85°C ambient, the T7 is the correct choice.

Is STM32L053C8T7 suitable for replacing STM32L052C8T6 in an existing design?

The STM32L053C8T7 adds an integrated EEPROM (2 KB) and a segment LCD driver that the STM32L052C8T6 lacks. If your firmware does not rely on those peripherals, the pinout and memory map are compatible across the STM32L0 value-line family, so a drop-in replacement is feasible with a firmware update. Verify the supply voltage range and temperature grade match your BOM requirements.
