SAN DIEGO, Jan. 28, 2013 /PRNewswire/ --A leading innovator of energy
management, communication and control solutions for the smart grid, Texas
Instruments Incorporated (TI) (NASDAQ: TXN) today announced 60 new fully
integrated metering SoCs to be demonstrated at DistribuTECH 2013. The
MSP430F677x SoCs can achieve electricity measurement accuracy that meets or
exceeds global regulatory requirements for smart polyphase e-meters including
IEC 62053-22 and ANSI C12.20 Class 0.2 standards. In addition, the large
integrated memory on MSP430F677x SoCs enables more sophisticated metering
features; while advanced anti-tampering protection helps electric utilities
prevent power theft and meter manipulation.

To achieve the highest level of meter accuracy, an enhanced analog front end
(AFE) with up to seven 24-bit sigma-delta data converters on the MSP430F677x
SoCs provides class-leading accuracy across a full 2000:1 input current range
throughout -40 degrees C to +85 degrees C. Combined with up to 512KB Flash
and 32KB SRAM memory integrated on-chip, developers can incorporate more
sophisticated metering features like dynamic pricing tables for time of use,
large buffer for interval data, DLMS/COSEM for meter data formatting, and
communication stacks for both wired and wireless protocols.

To protect electric utilities from energy theft and meter manipulation, the
MSP430F677x SoCs include several advanced anti-tamper protection features. For
example, dedicated pins associated with the on-chip real-time clock (RTC)
detect and time-stamp meter tampering so utilities can easily track, reduce
and prevent additional meter corruption. In addition, a 128-bit
hardware-accelerated Advanced Encryption Standard (AES) module speeds
encryption time compared to a traditional software implementation, improving
meter security, performance and reducing energy consumption.

The new MSP430F677x SoCs, along with accompanying software support, make
development quicker and more affordable. The free MSP430™ Energy Library code
performs all of the polyphase meter calculations for energy and power that are
required for ANSI/IEC qualified meters and provides an easy starting point for
customers developing utility meter products. For more information on the new
MSP430F677x SoCs, visit www.ti.com/f677x-pr-lp.

Additional features and benefits of MSP430F677x SoCs:

  oIncreased memory density allows developers to connect to wired and
    wireless communications standards including ZigBee, wM-Bus, PRIME, G3-PLC
    and RF mesh networks.
  oSix configurable serial communications peripherals allow combination of
    four UART, six SPI or two I2C ports to allow connectivity to multiple
    wired communication standards.
  oIntegrated display drivers support 8-Mux 320-segment LCD controller
    enabling more detailed displays and extended language support.
  o128-bit hardware-accelerated AES module speeds encryption time compared to
    a traditional software implementation and allows for secured wired and
    wireless communication.

Pricing and availability
Developers can immediately begin evaluating MSP430F677x SoCs with the
EVM430-F6779 polyphase e-metering evaluation module for USD $299. Polyphase
MSP430F677x (AES) SoCs and MSP430F6779x (non-AES) SoCs start at $6.60 for 1Ku
units. Please contact your TI Smart Grid sales representative for more order
