San Jose, Calif. NXP Semiconductors' NXP LPC2300 and LPC2400 ARM7 based microcontrollers are said to be the first such devices having two ARM high-speed buses (AHB) that enable simultaneous operation of high-bandwidth peripherals such as Ethernet, USB On-The-Go (OTG), USB Host, CAN, SDRAM and on-chip Flash. The NXP LPC2400 is also claimed to be the only ARM7 MCU with two-port USB Host capability permitting new advances for multiple communications applications.
"The explosive growth of Ethernet in the industrial networking and infotainment markets has created tremendous demand for high-performance 32-bit MCUs with Ethernet and other high-bandwidth communications peripherals," said Geoff Lees, general manager, microcontroller product line, NXP Semiconductors, the newly independent semiconductor company founded by Philips.
The dual AHB buses and three independent direct memory access engines allow multiple high-bandwidth peripherals to operate at the same time without overwhelming the bus and improve the worst case by over 50 percent.
The large array of peripherals available on both the NXP LPC2300 and LPC2400 include two AHB buses, Ethernet, two CAN controllers, four UARTs, SPI, SSP, three IC buses, I2S, RTC, ADC/DAC and SD/MMC Card interface. The NXP LPC2400 also includes USB OTG integrated with two-port host capability, and external interfaces to SDRAM and NOR Flash. The LPC2300 and LPC2400 are also the first ARM7 MCUs with a real-time clock (RTC) with 2KB of battery back-up SRAM, which allows the RTC to continue running even when the chip's power is shut down.

"The NXP LPC2300 and LPC2400 will allow designers more freedom for innovation in industrial networking environments," said Lees.
The NXP LPC2300 microcontroller is available immediately. The NXP LPC2400 microcontroller will be available in November 2006. In quantities of 10,000, the microcontrollers are priced at: LPC2364 $3.99, LPC2366 $4.75, LPC2368 $5.49 and LPC2378 $6.29. The LPC2300 will be shown at the ARM Developers' Conference in Santa Clara, Calif., October 3 to 5, 2006, at Booth #612.
