Nuvoton IC M263SIAAE - IC-2617-D
The Nuvoton Technology Corporation M263SIAAE belongs to the NuMicro M261/M262/M263 series, designed for low-power embedded systems requiring reliable connectivity and security. It uses an Arm Cortex-M23 processor based on the Armv8-M architecture, operating at up to 64 MHz, with 512 KB of dual-bank Flash memory supporting over-the-air (OTA) firmware updates and 96 KB of SRAM.
The microcontroller integrates secure boot, hardware AES encryption, a True Random Number Generator (TRNG), programmable execute-only memory (XOM), and unique device identification features. Its peripheral set includes USB 2.0 Full-Speed OTG, CAN 2.0B, SD host controller, UART, SPI, I²C, I²S, ADC, DAC, and PWM interfaces. Multiple low-power operating modes and a 1.8 V to 3.6 V supply range make it suitable for battery-powered IoT devices and industrial applications.
