The MSP430F5438AIPZR is a microcontroller manufactured by Texas Instruments that features a 16-bit architecture and is part of the highly efficient MSP430 family of microcontrollers. This MCU offers a variety of functions, including a wide range of analog and digital peripherals, an on-chip oscillator, Flash memory for code storage, and up to 64KB of RAM. This MCU features an advanced set of ultra-low power features such as the MSP430's 2-stage low-power architecture, the ability to run at full performance at extended temperatures, and sleep modes. This low-power design enables system designers to take a very cost-effective approach in creating systems that can run for extended periods and perform a wide range of tasks in power-constrained environments. This MCU is also highly customizable with up to 2 KB of on-chip RAM, as well as, modular port pins for extended control.
