Microcontrollers cut power for mobile devices

New from Fujitsu is the FRLite series of microcontrollers.

New from Fujitsu is the FRLite series of microcontrollers.

Designed to consume less power, the new series is the latest addition to the FR family of 32bit RISC microcontrollers.

The first two FRLite products (the MB91F233 and MB91232L), both with embedded LCD controllers, are targeted at mobile devices and digital consumer electronics.

The new series shares the same architecture as the rest of Fujitsu's FR family of high-performance 32bit microcontrollers.

Making the most of Fujitsu's extensive library of intellectual-property assets, these new products support the same high-speed 33MHz operation as their predecessors, but in a smaller package.

Furthermore, by optimising the clock-driving circuitry, the power consumption of the CPU core has been slashed to 1mA/MHz, a 40% reduction compared to the company's existing lineup of microcontrollers based on the 32bit RISC CPU core.

The new series also benefits from Fujitsu's advanced system-on-chip development environment, which significantly reduces turnaround times.

This enables the company to cut the amount of time between the receipt of a customer's specifications and the shipment of samples by half compared to conventional design methods.
