February 15, 2010 -- today announced availability of the LPC1769 and LPC1759 microcontrollers that operate at 120MHz, the fastest ARM Cortex-M3 MCUs available. With 256-point 16-bit FFT execution time of less than 190µs, this is 54% faster than the nearest Cortex-M3 alternative and challenges low-cost DSPs in performance. For 1024-point 16-bit FFT the execution time is less than 0.89ms. These times include the FFT initialization and overhead of the algorithm.

The LPC1769 and LPC1759 MCUs feature 512-kByte Flash, 64-kByte SRAM, USB 2.0 Host/ On-the-Go/ Device, CAN 2.0B interfaces, 12-bit ADC, 10-bit DAC, I2C, SPI, UARTs and many other peripherals. The LPC1769 also adds a 10/100 Ethernet controller with a dedicated Ethernet direct memory access (DMA) controller.

The LPC1700 series is already supported by a large number of development tools, real-time operating system (RTOS), middleware, and technical support services from industry leading tool vendors including IAR, Keil, Hitex, Code Red, and many others, such as:

LPCXpresso provides designers with an end-to-end solution from initial prototype evaluation to final production. This development platform focuses on ease-of-use and faster product development time and supports all derivatives of Cortex-M0/M3 families and specific devices from the LPC2000 and LPC3000 families including the LPC1700 series. mbed (online rapid prototyping tool) enables engineers to create functioning prototypes for quick experimentation and more inventive and productive development.

A complete DSP Library is available on the NXP wbsite, including:

License and royalty-free source code libraries. Highly optimized 16- and 32- data width FFT, PID control with documentatio.n FIR and IIR Filters: IIR (ARMA), biquad, 16- and 32-bit single stage for both. Random number generator and resonator function. Dot product and cross product of vectors. License- and royalty-free VDE IEC 60335 Class B test libraries approved by the VDE (Verband der Elektrotechnik Elektronik Informationstechnik e.V. German Association for Electrical, Electronic & Information Technologies) testing and certification institute. These free NXP libraries eliminate the need for the designer to develop their own self-test routines.
