TI creates a new low power (lower! as if the old MSP430 wasn’t already a true low power mcu) mcu product line.  The announced power reduction is @50% with new “Wolverine” MCU platform.

– Active power as low as 100 µA/MHz
– <400 nA standby with RTC and brown-out protection
– 250× less energy per bit with FRAM
– < 7 µs to wake to active from standby

The announced “Wolverine” keeps as many peripherals as can be in a “retention” mode using a power gating controller. Only the needed modules are fully powered, the idle ones are in “retention” mode.

The FRAM unified memory architecture can also lower all the memory power requirements.

It looks like one of the big energy efficient boards but at a nano-scale.

The announced voltages are 0.9v(GO, TI, GO!), 1.8v, 3.3v and 5v.
