Product details

32 MHz Cortex-M0+ with 64 KB flash — sensor-node sweet spot

The STM32L051R8T7: The industrial temperature grade (-40°C to 105°C) qualifies it for outdoor enclosures, engine-bay modules, or cold-chain loggers.

Peripheral set and I/O — 51 pins, serial, PWM, DMA

The connectivity block includes I2C, SPI, UART/USART, and IrDA — covering the common serial buses for MEMS sensors, environmental monitors, and radio modules. On-chip peripherals include a 16-channel 12-bit ADC, DMA controller, PWM timers, an I2S interface for audio codecs, plus brown-out detect and POR for reliable power-on sequencing.

Frequently asked questions

Where can I buy STM32L051R8T7 and get a price?

The STM32L051R8T7 is available to order through our desk. Submit an RFQ with your target quantity; we confirm availability and current pricing from authorized and independent distribution channels at quote time.

What is the closest pin-compatible alternative in the STM32L0 family?

The T6 is a drop-in replacement for designs that do not need the extended temperature range.
