The 29 I/O lines in the 36-WLCSP package give reasonable pin availability for a compact design. ## 36-WLCSP: tiny footprint, rework considerations Board area is minimal, ideal for space-constrained PCBs in wearables or sensor modules. Rework requires a hot-air profile matched to the small thermal mass; the package is moisture-sensitive, so bake before reflow if the sealed bag has been open past the floor-life window. The 29 I/O are distributed as solder bumps on a fine pitch — verify the PCB land pattern against the ST application note before layout. The base product number is STM32L052, and the full family includes density and package variants for design flexibility.","metaTitle":"STM32L052T8Y7TR STM32L0 ARM Cortex-M0+ MCU, 32 MHz","metaDescription":"STMicroelectronics STM32L052T8Y7TR 32-bit MCU: 32 MHz Cortex-M0+, 64 KB Flash, 8 KB SRAM, 2 KB EEPROM, 36-WLCSP, -40 to 105°C.

The key difference is the STM32L052 includes USB and a DAC, while the STM32L051 omits those peripherals. Both share the same 32 MHz Cortex-M0+ core, 64 KB Flash, and 36-WLCSP package. For a drop-in replacement check the pinout — the USB pins on the L052 are no-connects on the L051, so the PCB layout is compatible."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L052T8Y7TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L052T8Y7TR when reusing this data.
