5xx microcontrollers simplify co-processor design
By eliminating the need for level translators, Texas Instruments' new MSP430F521x/522x range of 5xx microcontrollers is said to reduce system cost and increase flexibility.

The devices support a main supply rail of 1.8 to 3.6V and an I/O supply rail of +/-1.8V for simplified co-processor design, and are targeted at applications such as sensor hub, keyboard control and health and fitness.
According to TI, the mcus can operate as an ultra low power co-processor to higher power/performance devices such as the company's OMAP processor and Sitara platforms.
They also offer a fast wake up time of 3.5us low power consumption of 1.4uA in standby mode, meaning battery life can be extended from hours to days.
