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.
