NXP Semiconductors unveils industry’s first ARM7 microcontrollers with dual high-speed buses
NXP LPC2300 and LPC2400 feature two AHB buses enabling simultaneous operation of Ethernet, USB, CAN, SDRAM and other peripherals
NXP Semiconductors, the newly independent semiconductor company founded by Philips, today announced
the industry's first ARM7-based microcontroller (MCU) series with dual high-speed buses for
simultaneous communications operations. The NXP LPC2300 and LPC2400 are the only ARM7 MCUs with two
ARM high-speed buses (AHB) enabling 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 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. "NXP is the first to fulfill this need with the only ARM7-based
microcontroller series that can perform multiple high-speed communications operations simultaneously.
The NXP LPC2300 and LPC2400 will allow designers more freedom for innovation in industrial networking
environments."
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. This makes the NXP LPC2300 and LPC2400 ideal for a wide range of high-performance
communications applications such as industrial networking, infotainment, consumer and medical devices,
and point-of-sale equipment. The NXP 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 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 I²C 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. These two microcontrollers further strengthen NXP's
comprehensive portfolio of best-in-class ARM-based microcontrollers, making it the most comprehensive
collection in the industry.
Availability
The NXP LPC2300 microcontroller is available immediately. The NXP LPC2400 microcontroller will be
available in November 2006. The LPC2300 will be shown at the ARM Developers' Conference in Santa
Clara, Calif., October 3 - 5, 2006, at Booth #612.
