For system communication the MCU provides I²C, IrDA, SPI, UART/USART, and USB interfaces. The data converter block integrates a 16-channel 12-bit ADC and a single 12-bit DAC, enough for sensor acquisition and analog output in a mixed-signal control loop.
An internal oscillator is on-die, reducing external BOM count for clock generation.
Yes, the STM32L052R8T7 and STM32L052R8T6 share the same base product number STM32L052 and the same 64-LQFP package. The difference is the temperature grade: the T7 suffix indicates the -40 to 105°C range, while the T6 suffix covers -40 to 85°C. Pin compatibility is identical across the STM32L052 value-line density options in the same package.
The full datasheet and reference manual for the STM32L052 series are published by STMicroelectronics on their website under the base product number STM32L052. The document covers the complete register map, electrical characteristics, and application notes for this MCU.
The STM32L052R8T7 runs at a maximum core speed of 32 MHz. This is the standard clock rate for the STM32L0 series, balancing throughput against the ultra-low-power profile of the ARM Cortex-M0+ core.
