Product details
Overview
MSP430F6775IPZR from Texas Instruments is a polyphase metering SoC designed for 3-phase electronic watt-hour meters, featuring seven 24-bit sigma-delta ADCs, 128KB flash, 16KB RAM, and <0.1% energy measurement accuracy over 2000:1 dynamic range at phase current. It integrates LCD controller (320 segments), AES-128 encryption, RTC with temperature compensation, and supports ANSI C12.20/IEC 62053 compliance.
For engineers reviewing the MSP430F6775IPZR datasheet, MSP430F6775IPZR pinout, MSP430F6775IPZR application, or MSP430F6775IPZR equivalent, key selection considerations include its 100-pin LQFP (PZ) package, ultra-low-power LPM3.5 mode (0.34 µA), dedicated pulse output pins for active/reactive energy calibration, and support for shunt/CT/Rogowski sensor interfaces in utility metering systems.
Technical Context
The MSP430F6775IPZR implements a 25-MHz MSP430 CPU with 32-bit hardware multiplier to execute TI's energy measurement software library for real-time kWh/kVARh calculation, tariff management, and AMR/AMI communication stack processing. Its analog front-end includes seven independent SD24_B modulators with differential inputs, programmable gain, and digital phase correction for CT-based current sensing.
It features six eUSCI modules configurable as UART, SPI, or I²C; four 16-bit timers with nine capture/compare registers; and dual power domains (AVCC/DVCC) with automatic supply switching between main and backup rails. The device operates across 1.8–3.6 V and –40°C to +85°C, with dedicated auxiliary supplies (AUXVCC1–3) for metrology subsystem isolation.

The MSP430F6775IPZR offers multiple low-power modes including LPM3 (2.1 µA), LPM3.5 (0.34 µA), and LPM4.5 (0.18 µA) at 3 V. In LPM3.5, the RTC, backup RAM, and tamper detection remain active while the CPU and most peripherals are powered down - ideal for maintaining time and critical state during AC mains failure.
Can the MSP430F6775IPZR drive a 320-segment LCD directly without external components?
Yes, the MSP430F6775IPZR includes an integrated LCD_C controller supporting up to 320 segments with internal charge pump and programmable contrast control.
