Recently, as an innovative manufacturer with leading positions in smart grid energy management, communication and control, Texas Instruments announced the launch of 60 new fully integrated metering SoCs, which will be exhibited at DistribuTECH 2013. The MSP430F677x SoC can achieve accurate energy measurement and meet or even exceed the global regulatory standards for smart multi-phase electronic energy meters, including IEC 62053-22 and ANSI C12.20 level 0.2 standards. In addition, the large integrated memory of the MSP430F677x SoC contributes to more precise metering functions, and advanced anti-tamper protection can protect utility companies against electricity theft and altered meters.
To achieve the highest meter accuracy, the MSP430F677x SoC uses an enhanced analog front end (AFE) and is equipped with 7 sets of 24-bit ΔΣ data converters for the entire 2000: 1 input current range from -40 ° C to + 85 ° C Achieve the best accuracy among products of the same level. Using a single chip that integrates 512KB flash memory and 32KB SRAM memory, developers can combine more precise metering functions, such as dynamic price lists calculated on a time-by-time basis, large buffers for interval data, DLMS / COSEM for meter data formats, and wired and wireless Communication stack of communication protocol.
In order to prevent utility companies from stealing electricity and altering meters, the MSP430F677x SoC has built-in advanced tamper protection functions. For example, the dedicated pins of the single-chip real-time frequency (RTC) can detect and use time stamps to prevent meter tampering. Therefore, utility companies can track, reduce, and prevent meter damage. In addition, the 128-bit hardware-accelerated advanced encryption standard (AES) module's encryption time is faster than traditional software implementation, so it can improve the safety and performance of the meter and save power consumption.
The new MSP430F677x SoC provides accompanying software to help accelerate development and achieve economical results through tying. The free MSP430 Energy Library program code can perform all multiphase energy meter calculations for the energy and power required by ANSI / IEC standard electricity meters, and can be used as a reference for customers to develop energy meter products.

Additional features and advantages of MSP430F677x SoC:
The increased memory density helps developers use ZigBee, wM-Bus, PRIME, G3-PLC and RF mesh networks to connect to wired and wireless communication standards.
6 configurable serial communication peripherals can be combined with 4 UART ports, 6 SPI ports or 2 I2C ports, so it can be connected to a variety of wired communication standards.
The integrated display driver supports an 8-mux configuration 320-segment LCD controller, which can display more detailed content and expand language support.
The encryption time of the 128-bit hardware-accelerated AES module is faster than traditional software implementation, which helps protect wired and wireless communications.
Availability
Developers can start evaluating the MSP430F677x SoC with the EVM430-F6779 multiphase electronic energy meter evaluation module today. Multi-phase MSP430F677x (AES) SoCs and MSP430F6779x (non-AES) SoCs are available for order today.
