STM32L151RET6
STMicroelectronicsSTM32L151RET6 is a low-power Arm Cortex-M3 microcontroller from STMicroelectronics running at 32 MHz, with 512 KB of Flash, 80 KB of SRAM and 16 KB of on-chip EEPROM, plus USB connectivity and two operational amplifiers, in an LQFP-64 package (10 x 10 mm) rated from -40 C to +85 C. ST lists this exact order code as Active. The on-chip EEPROM removes an external memory device from parameter-storage designs, and the dual op amps reduce the analog front-end parts count, which suits battery-powered metering, sensing and data-logging equipment with long service intervals. Selection advice: the RE letters fix the LQFP-64 package and the 512 KB Flash configuration, so it is the code to pick when firmware headroom matters more than the smallest footprint; confirm the full STM32L151RET6 string when ordering, as neighbouring codes in the series differ in memory size and package. Parameters verified against STMicroelectronics documentation.

STM32L151RET6 FAQ
What should I check before substituting STM32L151RET6 with another Arm Cortex-M3 microcontroller?
Match the full ordering code, not the series name: package (LQFP-64 (10 x 10 mm)), temperature grade and packing all ride on the suffixes. A same-series code in a different package is a different orderable device, so confirm the substitute against the STMicroelectronics datasheet before changing the BOM.
