Processors suit communication-heavy applications

The LPC2900 is ideal for high-performance and communication-heavy applications such as motor control, CAN gateways, PLC, industrial networking and in-car entertainment.

NXP Semiconductors has released the LPC2900 series of ARM968E-S processors, aimed at applications in industrial, medical, motor control and automotive industries.

They provide designers with a cost-effective, flexible, low-power solution.

The LPC2919, LPC2917 and LPC2915 are based on 80MHz ARM968E-S MCUs with two CAN controllers and two LIN controllers, providing connectivity and gateway options that are suited to applications such as industrial automation and in-vehicle networking.

With the help of an on-chip power management unit (PMU), the LPC2900 can consume power more efficiently for low-power applications.

Peripherals such as high-speed pulsewidth modulators (PWMs) and UARTs can be clocked independently at different clock rates to provide further flexibility in minimising power consumption.

Features including dual CAN interfaces and two LIN masters, standard serial buses, plus a sophisticated PWM and two analogue to digital convertors (ADCs) make the LPC2900 ideal for high-performance and communication-heavy applications such as motor control, CAN gateways, PLC, industrial networking and in-car entertainment.

"Growth in 32bit ARM technology-based microcontrollers is now steadily outpacing the growth of other proprietary architectures".

"The LPC2900 MCUs promises to continue NXP's market lead and strategically complement our LPC2000 and LPC3000 product lines to provide our customers with the broadest ARM MCU offering in the industry", said Geoff Lees, General Manager, Microcontroller Product Line, NXP Semiconductors.

"The LPC2900 family provides an advanced system-level solution ideally suited to complement our ARM7TDMI and ARM926EJ processor-based products with MCUs based on the ARM968E-S".

Featuring a simplified design, the three devices offer consistent peripherals and code compatibility.

The LPC2917 and LPC2919 have 32bit external memory controllers that support static memory devices, including RAM, ROM, Flash, burst ROM, and external I/O devices.

The system can support up to 768Kbyte of on-chip Flash and 80kbyte SRAM.

The SRAM is subdivided into a 16Kbyte tightly coupled memory (TCM) for data and 16Kbyte TCM for code as well as 48Kbyte general-purpose SRAM.

Integrated CAN 2.0B controllers offer FullCAN mode for message reception, triple transmit buffers with automatic priority scheduling, and extensive global CAN-acceptance filtering for high-performance gateway functionality.

For compatibility with existing tools, each device uses the standard ARM test/debug JTAG interface.
