The separate 256-byte info memory segment is useful for storing calibration coefficients, serial numbers, or configuration parameters that survive firmware updates.","metaTitle":"TI MSP430A142IRHAR 16-bit MCU, 16 MHz, 32 KB Flash, 40-VQFN","metaDescription":"Texas Instruments MSP430A142IRHAR 16-bit MCU, 16 MHz, 32 KB Flash, 1 KB RAM, 32 I/O, I²C/SPI/UART, -40°C to 85°C, 40-VQFN.
