Three 24-bit sigma-delta ADCs — the metering-specific peripheral set
The MSP430F6736AIPZR: Three independent 24-bit sigma-delta ADCs and an 8-channel 10-bit SAR ADC are on-chip. This supports polyphase energy metering with simultaneous sampling per phase.
Industrial temperature range — outdoor enclosure and factory-floor fit
That puts it into outdoor meter cabinets that see winter lows, substation enclosures with solar gain, and factory-floor panels where ambient heat from adjacent drives raises the internal air temperature. The brown-out detect and POR peripherals are on-chip, so the reset circuit needs no external supervisor — one less component on the BOM for a cost-sensitive meter design.
The 16-bit CPUXV2 core is supported by TI Code Composer Studio and IAR toolchains.
TI lists the MSP430F6736AIPZR as Active. The 'A' revision includes fixes documented in TI's datasheet revision history.
