The 16KB of Flash program memory and 1K x 8 of RAM mean the firmware footprint needs to be lean; this is the entry-density tier of the F673x metrology series. ## The ADC array — why this part exists The headline differentiator is the data converter section: three independent 24-bit sigma-delta ADCs for simultaneous voltage and current channel sampling, plus five 10-bit SAR converters for auxiliary measurements like temperature or neutral current. This is the core of an energy metering SoC — the sigma-delta channels handle the high-resolution power calculation loop while the SAR ADCs monitor housekeeping signals. The 25MHz CPUXV2 core has enough headroom to run the metrology library and communication stack without a second processor. The integrated LCD driver saves a separate controller chip on the bill of materials. Brown-out detect, POR, and the watchdog timer are standard on the MSP430 platform and help the meter survive supply glitches without corrupting the accumulated energy registers. Supply range of 1.8V to 3.6V lets it run from a single lithium cell or a 3.3V rail without a separate regulator. It is a current-production device in the MSP430F6xx metrology family.","metaTitle":"TI MSP430F6730IPNR 16-bit MCU, 25MHz, 16KB Flash, 3x24b ADC","metaDescription":"Texas Instruments MSP430F6730IPNR 16-bit MCU with 25MHz core, 16KB Flash, 1KB RAM, 3x24-bit sigma-delta ADCs for energy metering.
