The STM32L496VGT6P is an STMicroelectronics 32-bit MCU built around an ARM Cortex-M4 core clocked at 80 MHz, with 1 MB of Flash and 320 KB of SRAM.
The supply range covers single-cell Li-ion (3.0 V to 4.2 V) down to near-dead alkaline or NiMH stacks.
100-LQFP — rework-friendly, 83 I/O accessible
The 100-LQFP (14x14 mm) is a standard fine-pitch QFP with 0.5 mm lead pitch. It reflows cleanly with a hot-air station or convection oven, and the exposed leads make inspection and hand rework straightforward — no hidden balls, no X-ray needed.
The part is ROHS3 compliant.
