It carries 256 KB of Flash and 64 KB of SRAM. On-chip peripherals include brown-out detect, DMA, a segment LCD controller, PWM timers, and a watchdog. Connectivity covers CANbus, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, UART/USART, and USB — enough to interface with most industrial fieldbuses and external memory without glue logic. The 52 I/O lines give headroom for parallel sensor arrays or a local HMI keypad. The manufacturer lists this part as Active, though some distribution channels flag an end-of-life hot status. The base product number STM32L433 opens the door to pin-compatible density variants in the same WLCSP footprint if a last-time-buy or alternate source is needed later.","metaTitle":"STM32L433RCY3TR ARM Cortex-M4 MCU, 80 MHz, 256 KB Flash, WLCSP","metaDescription":"STMicroelectronics STM32L433RCY3TR 32-bit MCU with 80 MHz Cortex-M4, 256 KB Flash, 64 KB RAM, -40 to 125°C, 64-WLCSP.
