It includes I²C, SPI, UART, IrDA, LIN, DMA, PWM, and a 12-bit ADC. ## NRND — sourcing reality and the replacement path The MSP430F5437IPN carries an NRND status from Texas Instruments. Communication interfaces cover I²C, IrDA, LIN, SCI, SPI, and UART/USART — enough for multi-protocol fieldbus adapters or sensor hubs. The 16-channel 12-bit ADC with internal oscillator means you can sample analog inputs without an external clock source. The 67 I/O lines give headroom for parallel displays or keypad matrices.","metaTitle":"TI MSP430F5437IPN 16-bit MCU, 18 MHz, 256 KB Flash, 80-LQFP","metaDescription":"MSP430F5437IPN 16-bit MCU from TI, MSP430F5xx series, 18 MHz, 256 KB Flash, 16 KB RAM, 67 I/O, -40 to 85°C.
