The three 24-bit sigma-delta ADCs digitize a voltage and current pair simultaneously. The 24-bit resolution delivers dynamic range for crest-factor signals typical in utility revenue metering.
Rated for -40°C to 85°C, this MCU is suited for outdoor meter cabinets and substation enclosures. The peripheral set includes brown-out detect and reset, POR, PWM, WDT, and an LCD driver.
The MSP430F6735IPN is supplied in an 80-LQFP package (12x12 mm). The pinout is documented in the device datasheet and includes 52 I/O lines plus dedicated ADC, serial interface, and LCD segment pins.
The core operates at 25 MHz, which is the maximum clock rate for the MSP430 CPUXV2 in this device.
