On-chip peripherals include a 16-channel 12-bit ADC, a single 12-bit DAC, brown-out detect, DMA, I²S, PWM, and a watchdog timer. Connectivity covers I²C, IrDA, SPI, UART/USART, and USB — the USB interface is a key differentiator for this density tier, enabling direct PC connection without an external bridge chip.
Yes, the connectivity set includes USB alongside I²C, IrDA, SPI, and UART/USART.
Within the STM32L0 series, the STM32L052R6H6 shares the 64-TFBGA footprint with other STM32L052 density variants (e.g., STM32L052R8 with 64 KB Flash). Pin compatibility holds across the STM32L052 value-line options, so a BOM swap to a higher Flash density is possible without a board spin.
