TI samples MSP430F5259 ultra-low power MCU

TI has announced they’re accepting requests for samples of their MSP430F5259 Ultra-Low Power MCU. It features 1.8V split-rail I/O architecture without need for level shifters, 128Kb flash memory and 32Kb RAM for wireless protocol integration and eight serial interfaces for communication to sensors or peripheral devices. The component is available in 5mm X 5mm BGA and VQFN (RGC) 64 packages. The low power needs make them suited for always-on, battery-powered applications.

The product datasheet and an app note are available.

  1. the chip actually has 128 kilo*bytes* of Flash and 32 kilo*bytes* of RAM. This is important distinction since less honest manufactures like to inflate their numbers.

    1. Yes, it’s the old “Headline ratings”. That sort of thing is very common in things like Mosfet specs.
      I like the dual voltage capabilities, but I wish they would make it so the I/O supply can go to 5V, not just 5V tolerant, Some of us still need to use 5V and though technically over the threshold, 5V tolerant doesn’t always work that well in practise.
