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 190Ás, 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.
Availability and Pricing
Parts are currently available from Digi-Key and other NXP distributors worldwide with recommended distribution pricing in 10,000 quantities starting at just over $4. LPCXpresso and mbed development tools are available at all NXP distributors worldwide.
