16.384 MHz core with three 24-bit sigma-delta ADCs — the metering MCU
The MSP430I2030TRHBT: Its headline feature is three integrated 24-bit sigma-delta ADCs, making it a targeted choice for energy metering, flow sensing, and precision instrumentation where external analog front-ends would otherwise be needed. The 16.384 MHz clock rate sets the timing budget for the sigma-delta modulator and the serial interfaces.
16 KB Flash, 1 KB RAM — firmware update strategy matters
Program memory is 16 KB of Flash (16K x 8) with 1K x 8 of RAM. That Flash density is sized for a single metering firmware image with calibration constants; field-reprogramming is possible but the OTA staging area will need to share space with the active image. The RAM is tight — 1 KB — so data logging or buffered ADC samples must be managed carefully or streamed out via the serial interfaces.
ROHS3 compliance is confirmed.
