TI moves FRAM into the mainstream with Wolverine to cut power in half
Typical battery powered applications spend as much as 99.9 percent of their time in standby mode, and “Wolverine”-based microcontrollers consume 360nA in standby mode, more than doubling battery life. This also opens up the use of energy harvesting applications.
TI developed ultra low leakage (ULL) process technology that offers a 10x improvement in leakage and mixed signal with the transistors optimized across the whole temperature range. The improved 130 nm process technology, ultra-low-power MSP430 architecture and more than 30 power-optimized analog and digital components combined are a few of the integrated elements that deliver the power reduction.
Taking advantage of FRAM, the world’s lowest power memory, Wolverine-based microcontrollers can operate at less than 100 µA/MHz in active mode and consume 250x less energy per bit compared to Flash- and EEPROM-based microcontrollers.
In addition to these power advantages, FRAM is 100 percent non-volatile, which gives developers the low power, speed and flexibility of SRAM while retaining the key no-power storage capability of Flash. Customers are also not limited to the specific ratios of program-to-data memory inherent to traditional embedded systems – they can change this ratio at any time in the design cycle.
The new ultra-low-power architecture reduces power consumption with a fast wakeup time of 6.5µs and high precision peripherals such as internal power management and a 12-bit analog-to-digital converter (ADC) at 75µA. All of TI’s MSP430 microcontrollers are also augmented by the MSP430Ware software and resource package, as well as low-power code optimization software tools. This enables developers to immediately access and easily filter through all MSP430 microcontroller design resources by device, tool or software library to significantly ease design and shorten time to market.
