TI Korea (CEO Kent Jeon, www.ti.com/ww/kr ) January 29, 2013 – TI (CEO Kent Jeon), an innovative leader in energy management, communication, and control solutions for the smart grid, unveiled 60 new fully integrated metering SoCs at DistribuTECH 2013. The MSP430F677x SoCs not only meet global regulatory requirements for smart polyphase e-meters, including IEC 62053-22 and ANSI C12.20 Class 0.2 standards, but also boast electrical measurement accuracy that exceeds these standards. Furthermore, the MSP430F677x SoCs enable precise measurement capabilities through their large built-in memory, and advanced tamper-proof protection prevents power theft and meter malfunctions for power companies.

The enhanced analog front-end equips the MSP430F677x SoC with up to seven 24-bit sigma-delta data converters, achieving the highest level of meter accuracy by providing best-in-class accuracy over a full 2000:1 input current range at temperatures from 40°C to +85°C. Additionally, with up to 512KB of flash memory and 32KB of SRAM memory integrated on the chip, developers can focus on implementing more precise measurement functions, such as dynamic pricing for usage time, large buffers for interval data, and communication stacks for DLMS/COSEM wired/wireless protocols for formatting measurement data.

To prevent power company conductivity and meter malfunctions, the MSP430F677x SoC includes several advanced tamper-proof protection features. For example, by using dedicated pins for the on-chip Real-Time Clock (RTC) to detect meter tampering and display a time stamp, power companies can track, reduce, and even prevent additional meter damage. Additionally, the 128-bit hardware-accelerated Advanced Encryption Standard (AES) module offers the advantage of improved meter security and performance, as well as reduced energy consumption, by shortening encryption time compared to traditional software methods.

Software support features provided with the MSP430F677x SoC can shorten development time and further reduce costs. The free MSP430™ Energy Library code performs all energy and power-related polyphase meter operations required for ANSI/IEC certified meters. Companies developing utility meter products can utilize this code effectively for initial operations. (For more information on the MSP430F677x SoC, please refer to www.ti.com/f677x-pr-lp )

Additional Features and Advantages of the MSP430F677x SoC
• Increased memory density enables developers to connect to various wired and wireless communication standards, including ZigBee, wM-Bus, PRIME, G3-PLC, and RF mesh networks.
• Connectivity to multiple wired communication standards is possible by combining 4 UARTs, 6 SPIs, or 2 I2C ports through 6 configurable serial communication peripherals.
• The integrated display driver supports the 8Mux 320-segment LCD controller, enabling more detailed displays and extensive language support.
• The 128-bit hardware-accelerated AES module significantly reduces encryption time compared to traditional software methods and supports secure wired and wireless communication.

Price and Supply Timing
The MSP430F677x SoC with the EVM430-F6779 polyphase e-metering evaluation module is available for immediate purchase and evaluation at $299 per unit. The polyphase MSP430F677x (AES) SoC and MSP430F6779x (non-AES) SoC can be purchased for as little as $6.60 in quantities of 1,000.
