Product details

It runs at 32 MHz and carries 192 KB of Flash program memory, 20 KB of SRAM, and 6 KB of embedded EEPROM — enough for moderately sized firmware with nonvolatile parameter storage. The 48-UFQFN package with exposed pad keeps the footprint small while the pad helps pull heat out in compact enclosures.

Peripherals and connectivity for sensor fusion

The part includes a 10-channel 12-bit ADC, brown-out detect, DMA, I²S, PWM, and a watchdog timer. Connectivity covers I²C, IrDA, SPI, and UART/USART — enough to talk to common MEMS sensors, displays, and radio modules without an external interface chip.

37 I/Os in a 48-pin package — what that means for layout

With 37 I/Os brought out of a 48-UFQFN, the pin-to-pin pitch is tight — expect 0.5 mm or finer. The 1.65 V minimum supply means the I/Os are 3.3 V tolerant but not 5 V; level shifting is required for legacy 5 V peripherals.

Frequently asked questions

Is STM32L071CZU6 pin compatible with STM32L072?

The STM32L071 and STM32L072 share the same pinout in the 48-UFQFN package, but the L072 adds a USB controller and larger SRAM. Check the STM32L072 datasheet for peripheral differences before assuming a drop-in swap.
