STM32L552CET6                  Description

  Texas Instruments' MSP430 series of ultra-low power microcontrollers consists of multiple devices with different sets of peripherals suitable for different applications. The architecture is optimized through five low-power modes to achieve longer battery life in portable measurement applications. The device has powerful 16-bit RISC CPU, 16-bit register and constant generator, which can achieve the highest code efficiency. Both the MSP430x13x and MSP430x14x (1) series are microcontroller configurations with two built-in 16-bit timers, a fast 12-bit Adeband D converter (not implemented on MSP430F14x1 devices), one or two universal serial synchronous / asynchronous communication interfaces (USART), and 48 iMacro O pins.
