MSP430FR2155TRHAR

The Texas Instruments MSP430FR2155TRHAR is a 16-bit microcontroller based on a RISC architecture, capable of operating at speeds up to 24 MHz. It features 32KB of low-power ferroelectric RAM (FRAM) with built-in error correction code (ECC) and configurable write protection, offering unified memory for program, constants, and storage. The device includes 4KB of SRAM.

This MCU is equipped with high-performance analog peripherals, including a 12-channel, 12-bit analog-to-digital converter (ADC) with an internal reference, and two enhanced comparators (eCOMP). It also integrates a 6-bit digital-to-analog converter (DAC) for reference voltage. Connectivity options include I²C, IrDA, SPI, and UART/USART interfaces. The microcontroller operates within a wide supply voltage range of 1.8V to 3.6V and has an extended operating temperature range of -40°C to 105°C.

The MSP430FR2155TRHAR is housed in a 40-VQFN (6x6) package and supports surface mount mounting. It offers optimized low-power modes, with active mode consuming 142 µA/MHz and shutdown mode (LPM4.5) consuming as little as 42 nA. The part is designed for general-purpose applications requiring a balance of performance, low power consumption, and non-volatile memory.
