It carries 1 MB of Flash and 640 KB of RAM on-chip, with 110 I/O lines and a rich peripheral set including CANbus, USB OTG, multiple SPI/I²C/UART interfaces, and a 16-channel 12-bit ADC plus a 2-channel 12-bit DAC. ## Package and layout note The 132-UFBGA (7x7 mm) uses a fine-pitch BGA. A multi-layer PCB with via-in-pad or microvia capability is required, plus X-ray inspection after reflow.","metaTitle":"ST STM32L4R5QGI6STR ARM Cortex-M4 MCU, 120 MHz, 1 MB Flash","metaDescription":"ST STM32L4R5QGI6STR 32-bit MCU, ARM Cortex-M4 at 120 MHz, 1 MB Flash, 640 KB RAM, 132-UFBGA, -40 to 85°C.
