The 11 general-purpose I/O pins handle local control (relay drive, LED indication) and interface to a host via SPI or UART. Brown-out detection and a watchdog timer are built in, so an external supervisor IC is unnecessary. The 24-TSSOP package (4.4 mm wide) fits on compact two-layer boards common in smart-plug and power-monitor designs.","metaTitle":"TI MSP430AFE251IPWR 16-bit MCU, 12 MHz, 24-bit ADC, 24-TSSOP","metaDescription":"MSP430AFE251IPWR 16-bit MCU with 12 MHz core, 16 KB Flash, 512 B RAM, integrated 24-bit sigma-delta ADC.
