Low power MCU offers high computational strength

22 February 2006 DSP, Micros & Memory

The new LPC3180 32-bit microcontroller from Royal Philips Electronics provides high performance with low power dissipation, and is the only ARM9 microcontroller that provides a vector floating-point co-processor and integrated USB On-The-Go, as well as the ability to operate in ultra-low-power mode down to 0,9 V, according to the company. The LPC3180 is based on the popular, high-performance ARM926EJ-S core. The on-board MMU supports major operating systems including Linux, while the on-chip Java byte-code co-processor provides for basic security and authentication applications. Flexible power management allows high peak performance, especially for floating-point calculations. The new MCU is the only ARM9 microcontroller on the market today that offers a hardware vector floating-point unit for speed and efficiency. The hardware floating-point co-processor speeds up typical calculations by a factor of four to five in scalar mode and much more in optimised vector mode, states the company. The large array of peripherals available on-chip also include seven UARTs, SPI, I²pC, a realtime clock with a separate power domain, NAND Flash, and DDR memory controllers.
