It integrates a 10-channel 16-bit ADC, I²C and SPI serial interfaces, plus brown-out reset, POR, PWM, and watchdog timer peripherals — all in a 16-VQFN exposed-pad package measuring 4x4 mm. This is a low-pin-count, ultra-low-power MCU built for sensor readout, simple control loops, and battery-powered instrumentation where every microamp matters. ## Integrated ADC and serial interfaces reduce external BOM The on-chip 16-bit ADC with 10 multiplexed channels covers most transducer readout needs — thermocouple, RTD, strain gauge, or pressure sensor — without an external converter. I²C and SPI on the same silicon mean a single MSP430F2003TRSAT can talk to a digital temperature sensor, an EEPROM, and an RF transceiver over the two-wire bus while the ADC handles the analog front end.","metaTitle":"TI MSP430F2003TRSAT 16-bit MCU, 1KB Flash, 16 MHz, 16-QFN","metaDescription":"Texas Instruments MSP430F2003TRSAT 16-bit MSP430 CPU16 MCU, 1KB Flash, 128B RAM, 16 MHz, 10-channel 16-bit ADC, I²C/SPI, -40°C to 105°C, 16-VQFN.
