That makes it a direct fit for applications that log data, update firmware over the air, or need to retain calibration constants without a separate EEPROM. The 4 K x 8 RAM handles the stack and scratchpad. On the peripheral side: 36 GPIOs, a 10-channel 12-bit ADC, and serial interfaces covering I²C, SPI, UART, and IrDA. ## Package and footprint — 40-VQFN with exposed pad Housed in a 40-VFQFN with an exposed thermal pad (6x6 mm body), the package suits compact, thermally aware layouts. The pad needs a via array to the ground plane for heat sinking — without it, continuous operation near the 105°C limit and maximum I/O load will push junction temperature higher than the ambient rating alone suggests. ## Lifecycle and supply posture TI lists the MSP430FR2155TRHAT as Active.","metaTitle":"TI MSP430FR2155TRHAT 16-bit MCU, 32KB FRAM, 24MHz, 40-VQFN","metaDescription":"Texas Instruments MSP430FR2155TRHAT 16-bit MCU with 32KB FRAM, 4K x 8 RAM, 24MHz CPU, 36 I/O, 10x12b ADC, -40°C to 105°C.
