The 50 I/O lines give enough GPIO for parallel buses or a keypad matrix alongside the I²C, SPI, and UART peripherals. That means ST is still manufacturing this variant, and the supply chain is normal — no last-time-buy scramble, no forced redesign. The base product number STM32L071 covers a range of Flash and package options, so if this exact BGA variant becomes tight, a pin-compatible sibling in the same family is the first cross-reference to check.","metaTitle":"STM32L071RBH6TR ARM Cortex-M0+ MCU, 32 MHz, 128 KB Flash","metaDescription":"STM32L071RBH6TR: STM32L0 32-bit MCU, 32 MHz core, 128 KB Flash, 20 KB SRAM, 6 KB EEPROM, 64-TFBGA.

The BGA saves board area but requires a more careful reflow and inspection process. The core, memory, and peripheral set are identical across the two."},{"question":"What is the STM32L071RBH6TR's core speed?","answer":"The ARM Cortex-M0+ core runs at 32 MHz.
