2.1.1 Microcontroller

The MSP432E401Y is a 32-bit Arm Cortex-M4F based microcontroller with 1024KB of flash memory, 256KB of SRAM, 6KB of EEPROM, and 120-MHz operation, integrated 10/100 Ethernet MAC and PHY, integrated USB 2.0 connectivity with external high-speed USB 3.0 PHY capability, a hibernation module, a multitude of serial connectivity and motion control PWM, as well as a wide range of other peripherals. See the MSP432E401Y microcontroller data sheet for more complete details.

Most of the microcontroller signals are routed to 0.1-in (2.54-mm) pitch headers or through-hole solder pads. An internal multiplexor allows different peripheral functions to be assigned to each of these GPIO pads. When adding external circuitry, consider the additional load on the evaluation board power rails.

The MSP432E401Y microcontroller is factory-programmed with a quick start demo program. The quick start program resides in on-chip Flash memory and runs each time power is applied, unless the quick start application has been replaced with a user program. The quick start application automatically connects to http://ti.exosite.com when an internet connection is provided through the RJ45 Ethernet jack on the evaluation board.
