It is part of the STM32L4 series, ST's ultra-low-power line that still delivers DSP and FPU performance for signal processing. The 144-LQFP package gives you 115 I/O lines, which is enough to drive a parallel LCD, a memory bus, or a dense sensor array without needing a port expander. ## Industrial temperature range and wide supply — field-fit check If your design lives in a hot engine bay or a cold storage warehouse, the temperature grade covers it without needing a mil-spec uprate. ## On-chip peripherals that reduce BOM The integrated LCD driver saves an external display controller for segmented glass panels. Connectivity includes CANbus for industrial networks, USB OTG for host/device mode, and SAI for audio codec interfaces — all without extra transceivers on the basic links. ## Package and rework — no special gear needed The 144-LQFP with a 20x20 mm body is a standard QFP footprint. You can hand-solder it with a fine-tip iron or reflow it in a conventional oven. No BGA reball, no hot-air station required. If you are swapping one in the field, the pin pitch is wide enough to inspect with a loupe, and the orientation is marked by pin 1 chamfer. The product status is listed as active. That means ST is still manufacturing it, supporting it with errata and app notes, and accepting new orders. No last-time-buy window to chase, no end-of-life date to watch. For a production BOM, this is the green-light status you want.","metaTitle":"ST STM32L4Q5ZGT6P ARM Cortex-M4 MCU, 120 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L4Q5ZGT6P 32-bit MCU: ARM Cortex-M4 at 120 MHz, 1 MB Flash, 320 KB SRAM, 115 I/O, 144-LQFP.
