TI’s MSP4305xx MCUs feature independent 1.8V IO supply rail

The new MSP430F521x/F522x microcontroller family from Texas Instruments Incorporated supports a main supply rail (1.8V – 3.6V) and I/O supply rail (1.8V +/-10%), eliminating the need for level translators and offering system-level advantages such as reduced system cost and increased flexibility.

The F521x/F522x microcontrollers can operate as ultra-low-power co-processors to higher power/performance devices such as TI’s OMAP processor and Sitara platforms. The new MSP430 microcontrollers 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.

MSP430F521x/F522x microcontrollers are compatible with MSP430Ware software so developers can access code examples to simplify development and speed time to market. F521x/F522x microcontrollers are code compatible with all MSP430 devices for broader scalability across TI’s MSP portfolio.

Additional features

  • Bridge between application processor and other technologies, including sensors, keyboards, radio frequency (RF), Bluetooth low energy (BLE) technology and Wi-Fi, eliminating the need for expensive level shifting circuits to translate 1.8V signals to 3.6V signals, saving size, cost and power.
  • Active power at 290uA/MHz in Flash and 150uA/MHz in RAM, standby mode at 1.4uA and ultra-fast wakeup at 3.5us for ultra-low-power consumption.
  • Low-power peripherals including comparator, multiple communication interfaces (UART, I2C, SPI, GPIO), real time clock (RTC) module, 10-bit analog-to-digital converter (ADC) and multiple 16-bit timers.
  • Multiple package sizes offer versatility with 48- and 64-pin QFN, 80-pin BGA options with up to 128k memory and a 3.5mmx3.5mm YFF package (available in 1Q13), enabling small footprint in portable computing applications.

MSP430F521x/F522x microcontrollers are priced from $2.05 for 1K units and samples are immediately available.
