LONDON — NXP Semiconductors' LPC1700 series with the LPC1768 and LPC1758 microcontrollers, based on ARM's Cortex-M3 cores, have been tested and certified as the highest performance Cortex-M3 based microcontroller by the Embedded Microprocessor Benchmark Consortium (EEMBC). EEMBC says the LPC1700 executes application code on average 35 percent faster than other Cortex-M3 competitors when running at the same clock speeds, and suggests the performance advantage is even greater when the devices run at higher clock speeds. The EEMBC certification lab has tested the microcontroller at 72,100, and 120 MHz (overclocked?), the performance and efficiency put down as a consequence of the memory architecture of the microcontroller.
The LPC1750 and LPC1760 series are targeted at high-bandwidth communications peripherals. "The EEMBC results confirm that the LPC1700 series is now the fastest and most efficient Cortex-M3 available in the market," said Geoff Lees, general manager, microcontroller product line at NXP Semiconductors. The LPC1768 and LPC1758 are being shipped these days to distributors to be readily available very soon. Markus Levy, president of EEMBC, commented: "These certified EEMBC results highlight the fact that the design of the microcontroller and its memory interfaces is equally as important as the processor core itself." NXP offers a total of 9 different types for the LPC1750 and LPC1760 series. The specific devices are LPC1751, LPC1752, LPC1754, LPC1756, LPC1758, LPC1762, LPC1764, LPC1766, LPC1768. Memory ranges are from 32k Flash / 8k SRAM on the LPC1751 to 512k Flash combined with 64k SRAM on the LPC1768. |
