The Nuvoton M032LE3AE is a low-voltage 32-bit microcontroller designed for embedded systems requiring efficient processing, accurate analog measurement, and responsive control. Based on the Arm Cortex-M0 core, it operates at up to 48 MHz and integrates 128 KB Flash memory and 16 KB SRAM for program storage and runtime operations.
Operating from 1.8V to 3.6V, the M032LE3AE supports temperatures from -40°C to +105°C. Its 12-channel, 12-bit ADC provides conversion rates of up to 2 MSPS, while the 12-channel, 16-bit PWM supports precise control applications. Additional peripherals include USB 2.0 Full-Speed device connectivity, UART, I²C, SPI/I²S, USCI, timers, analog comparators, and PDMA channels.
The microcontroller also supports ISP, ICP, and IAP programming, along with 512 bytes of Security Protection ROM (SPROM). These integrated capabilities make it suitable for laser distance meters, air detectors and cleaners, mobile LCD panel controllers, micro printers, wireless charging equipment, and industrial control systems.
