Polyphase metering MCU with integrated sigma-delta ADCs and LCD drive
The Texas Instruments MSP430F6775IPEU is a 16-bit microcontroller from the MSP430F6xx family, running at 25 MHz. It carries 128 KB of Flash program memory and 16 KB of RAM, with seven 24-bit sigma-delta ADCs and an integrated LCD segment driver.
What the 25 MHz core and 7x24-bit ADC array mean for the BOM
The 25 MHz core runs a three-phase metrology algorithm while the seven sigma-delta ADCs sample continuously. This eliminates the need for a separate DSP or external ADC multiplexer.
Industrial temperature rating and package fit
Rated for -40°C to 85°C operation, the MSP430F6775IPEU is suited for outdoor meter enclosures. The 128-LQFP (20x14 mm) is a standard footprint for meter PCBs.
