Ultra-low power micro-controller

We need to develop a software for ultra-low power micro-controller that will control a watch LCD.

• The LCD will display time (HH:MM:SS), date (MM:DD) and the day (three dot-matrix letters). It also will display other information in a form of dots, bars etc (each mapped as single segments).

• See attached detailed drawing for the LCD.

• The LCD controller (part of the LCD itself) is SPLC502C (see attached datasheet). It will be connected to the uC using I2C bus.

• Micro-Controller's (TI's MPS430F5528) functionaity:

o Will be always powered and communicating with the LCD to update time and date (I2C master)

o Reading battery status from a fuel gauge and updating the display (I2C master)

o Control the sequencing of power supplies for the main system (GPIOs)

o Could be accessed by the host processor for updating other segments on the display (I2C slave)

o Read up to 4 pushbuttons used to update time and date (like standard G-Shock watch)

o Interrupt the host processor on any pushbuttons events or battery events (GPIO)

o Control several GPIOs based on commands received by the host (I2C slave)

Development tools: we'll provide an evaluation board with LCD attached.
