It packs 64 KB of Flash, 8 KB of SRAM, and 2 KB of EEPROM on a single die — enough for a sensor hub, a simple HMI back-end, or a battery-powered data logger that wakes, samples, and sleeps. At 32 MHz the Cortex-M0+ handles 16-bit PID loops and Modbus RTU framing. The 64 KB Flash holds a FreeRTOS kernel and peripheral drivers.","metaTitle":"ST STM32L051R8H6 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash, 64-TFBGA","metaDescription":"STMicroelectronics STM32L051R8H6 32-bit ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, 51 I/O, 64-TFBGA, -40 to 85°C.

The pinout follows the STM32L0 standard mapping for the 64-ball TFBGA variant — I/O, power, and ground assignments are shared with the STM32L052R8H6 and other 64-pin L0 siblings."},{"question":"Is the STM32L051R8H6 pin compatible with STM32L052R8H6?","answer":"Yes — both parts share the same 64-TFBGA footprint and pin assignment. The STM32L052 adds a USB 2.0 full-speed peripheral and a few extra analog features, but the pinout is identical, making it a drop-in upgrade path if the application needs USB connectivity."},{"question":"What programming tools and IDE support STM32L051R8H6?","answer":"ST's STM32CubeIDE, Keil MDK, and IAR EWARM all support the Cortex-M0+ core. Programming is done via the standard SWD/JTAG interface; ST-Link/V2 or any ARM-compatible debug probe works. The STM32CubeL0 HAL and LL drivers cover this exact part number."},{"question":"What is the maximum operating temperature for STM32L051R8H6?","answer":"The rated operating temperature range is -40 to 85 °C (industrial grade). For applications requiring 105 °C or 125 °C operation, look at the STM32L0 automotive-grade variants or the STM32L4 series."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L051R8H6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L051R8H6 when reusing this data.
