16 MHz MSP430 core with 32 KB Flash and 2 KB RAM
The MSP430F2370TRHAT is a 16-bit MCU from the MSP430F2xx family, built around the MSP430 CPU16 core running at 16 MHz. The internal oscillator keeps the BOM lean — no external crystal needed for the core clock.
32 general-purpose I/O lines give enough pins to interface with a keypad, a small LCD segment driver, and a few discrete sensors. On the serial side, the part supports I²C, SPI, UART/USART, IrDA, and LINbus — covering the common industrial and automotive bus standards without an external transceiver for the logic-level side. On-chip peripherals include a brown-out detect and reset, a POR circuit, a PWM timer, and a watchdog timer. The Slope A/D converter handles slow analog inputs like temperature or battery voltage without adding an external ADC.
Housed in a 40-VFQFN with exposed pad (supplier package 40-VQFN 6x6 mm), the part is surface-mount only. Tape & Reel packaging suits automated pick-and-place lines.
