ARM7 MCUs

Features: NXP Semiconductors, an independent semiconductor company

founded by Philips, has 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.
