The LCD driver peripheral can directly segment-drive a glass LCD panel without an external controller. The 52 I/O pins in the 64-LQFP package give enough GPIO for a keypad, encoder inputs, and a parallel display bus. ## Active lifecycle — no EOL risk for production builds It is ROHS3 compliant.","metaTitle":"STM32L433RCT3 STM32L4 MCU, 80MHz, 256KB Flash, 64-LQFP","metaDescription":"STM32L433RCT3 ARM Cortex-M4 MCU, 80MHz, 256KB Flash, 64K x 8 RAM, -40°C to 125°C, CAN, USB, QSPI.
