The STM32L052K8T6D: This MCU integrates a USB peripheral (I²C, IrDA, SPI, UART/USART, USB connectivity) and a 10-channel 12-bit ADC plus a single 12-bit DAC.
Housed in a 32-LQFP (7x7 mm) surface-mount package with 27 I/Os.
The STM32L052K8T6 and STM32L052K8T6D share the same core, memory, and package. The "D" suffix typically indicates a specific shipping or packing variant (e.g., tray vs. tape-and-reel). Functionally they are identical — both are 32 MHz Cortex-M0+ MCUs with 64 KB Flash, 8K x 8 RAM, 2K x 8 EEPROM, USB, and the same peripheral set. The difference is in the logistics packaging, not the silicon.
Yes, the connectivity list includes USB alongside I²C, IrDA, SPI, and UART/USART.
