The MSP430I2031TPWR: Three 24-bit sigma-delta converters sample voltage and current channels simultaneously. The 16.384 MHz clock supports real-time digital filtering.
The brown-out detect and watchdog peripherals are on-chip, reducing external supervisor IC count.
The MSP430I2030 is a pin-compatible sibling with the same Flash and ADC, but with fewer communication peripherals — it lacks the full set of I²C, IrDA, SCI, SPI, UART/USART that the I2031 carries. For designs needing all those interfaces, the I2031 is the correct fit.
Yes, the MSP430I2031TPWR is a superset replacement for the MSP430I2030 — same package, same Flash and RAM, same ADC, but with the full communication peripheral set. Drop-in compatible on the same PCB.
The MSP430 CPU16 core runs at 16.384 MHz, which is the clock rate used for the sigma-delta ADC sampling and real-time energy calculation loops.
