STM32L433VCT6 is ST's industrial 80 MHz Arm Cortex-M4 MCU with FPU in a 100-lead LQFP; its complete order code fixes the pin count, package and temperature grade.
Its 256 KB Flash and 64 KB SRAM keep code and working data on chip, setting firm limits for firmware and buffers.
The 12-bit ADC, two 12-bit DAC channels, comparators and op amp support measurement and analog-output paths on chip, provided channel and signal counts fit.
USB full-speed device, CAN 2.0B, SDMMC, Quad SPI and serial ports connect hosts, buses, cards and memory; their pin assignments must fit within 83 GPIO.
The LCD controller can drive 8 × 40 or 4 × 44 segments, allowing an integrated display path when those pins are available.
The 1.71–3.6 V VDD range and −40 to +85 °C ambient rating bound supply and thermal design, while the 14 × 14 mm, 0.5 mm-pitch LQFP fixes the board footprint.
