The new MSP430F67641 SoCs include high-performance delta-sigma analog-to-digital converters (ADCs) for energy measurement products requiring high accuracy across a wide dynamic range. An integrated 320-segment LCD eliminates the need for external drivers and enables developers to create the next generation of smart energy measurement devices with detailed displays and extended language support, while still maintaining low-power consumption in sleep mode.
In addition, the new MSP430F6779A metering SoCs include advanced security and electrostatic discharge (ESD) features. A 128-bit Advanced Encryption Standard (AES) hardware-accelerated module speeds encryption time, improves meter security and performance. With more flash memory integrated on-chip, smart grid developers can incorporate more sophisticated metering features like multi-dwelling dynamic pricing, large buffers for interval data, DLMS/COSEM for meter data formatting, and communication stacks for both wired and wireless protocols.
Developers will also benefit from TI's TPS54060 step-down converter that provides a regulated DC supply of 3.3V with low quiescent current to ensure full-speed operation of the MSP430F67641 and MSP430F6779A devices.
Additional features and benefits of TI's metering SoCs:
MSP430F67641 devices provide 0.5 percent accuracy and MSP430F6779A devices provide Class 0.1 accuracy across a 2000:1 dynamic range through -40 to +85 degrees Celsius.
MSP430F67641 SoCs provide multiple low-power modes and power consumption as low as 0.78-microA for developers needing to design ultra-low power metering devices.
Simultaneous sampling of the on-chip 10-bit successive approximation (
Integrated on-chip memory (128KB flash on MSP430F67641 and 512KB flash on MSP430F6779A) allow developers to include communication stacks for both wired and wireless protocols, including ZigBee, wM-Bus,power line communication (PRIME,
