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. ## Connectivity and peripheral set 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. ## Package and temperature grade for the field Housed in an 80-LQFP (12x12 mm body) with 52 I/O lines brought out, this is a surface-mount part that reflows with standard lead-free profiles. 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. ## Lifecycle and sourcing posture 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.
