It sits in the STM32L4 series, targeting applications that balance processing throughput with power efficiency — think industrial control, IoT gateways, and sensor fusion nodes. ## Memory and connectivity — sizing the BOM 1 MB Flash is enough for a full application stack with a FAT file system or a TCP/IP stack; 320 KB SRAM gives headroom for multiple data buffers and a modest RTOS heap. The connectivity set — CAN, USB OTG, SAI, and EBI/EMI — lets this MCU talk to a CAN bus, host a USB mass-storage device, drive an audio codec, or interface with external parallel memory. No external PHY or level shifters needed for most of these interfaces, which simplifies the PCB layout. ## What the peripherals enable The on-chip data converters — 16-channel 12-bit ADC and dual 12-bit DAC — cover analog sensor acquisition and control-voltage generation without external parts. Brown-out detect and POR keep the reset logic clean during power-up, which matters for battery-powered or intermittently powered designs.","metaTitle":"ST STM32L4Q5RGT6P ARM Cortex-M4 MCU, 120MHz, 1MB Flash","metaDescription":"STMicroelectronics STM32L4Q5RGT6P 32-bit MCU with ARM Cortex-M4 core at 120MHz, 1MB Flash, 320KB SRAM, 64-LQFP.
