IP builds low power memory for LCD drivers and touch screen controllers

October 21, 2014 // By Graham Prophet
In order to reach the stringent low power requirements of LCD drivers and touch screen controllers, Dolphin Integration has introduced a foundry-sponsored Single port RAM for the UMC 110 nm embedded Flash process.

Fabless companies targeting these applications have huge constraints both in terms of power consumption and area. Thanks to its dual voltage capability and its various operating modes, the power consumption of the Rhea SpRAM is drastically reduced and enables a significant extension of battery life for such power sensitive applications. The Rhea SpRAM not only reaches attractive low power consumption figures, but its smart architecture for the array periphery also offers the highest density to reduce silicon costs.

For a complete sub-system optimisation of power consumption, the Rhea SpRAM can be combined with Dolphin Integration's Typhoon 80251, a 16-bit MCU offering the best trade-off between processing power and low power consumption, and the R-Stratus-LP cache controller, specifically targeting low power optimisation of Flash memories.
