Texas Instruments Introduces MSP430F521x/F522x Microcontrollers
Texas Instruments introduced their new MSP430F521x/F522x microcontroller family. The new TI MCUs support a main supply rail (1.8V – 3.6V) and I/O supply rail (1.8V +/-10%). This eliminates the need for level translators and offers system-level advantages such as reduced system cost and increased flexibility. Samples of the MSP430F521x/F522x microcontrollers are available now. They’re priced from $2.05 for 1K units.
The F521x/F522x microcontrollers can operate as an ultra-low-power co-processor to higher power/performance devices such as TI’s OMAP processor and Sitara platforms. The MCUs can be used to offload functions such as sensor hub, keyboard control, battery/power management, capacitive touch, haptics and proximity detection with lower power consumption compared to running these within an application processor. With a fast wake-up time at 3.5us and as little as 1.4uA power consumption in standby mode, the F521x/F522x microcontrollers can extend battery life from hours to days.
