NXP Semiconductors has introduced the LPC2900 family of microcontrollers, expanding its already extensive range of ARM7 and ARM9-based MCUs. Built around the high-performance ARM968E-S processor, the LPC2900 offers a cost-effective, flexible, and low-power solution ideal for industrial, medical, engine control, and automotive applications. This new release includes three ARM9 models — the LPC2919, LPC2917, and LPC2915 — bringing NXP’s ARM-based MCU portfolio to over 50 different products. The LPC2900 will be showcased at the Embedded Systems Conference in Boston this week.
The LPC2900 is based on the 80-MHz ARM968E-S core, featuring two CAN controllers and two LIN interfaces, making it well-suited for industrial automation and in-vehicle networking. Its architecture is optimized for performance, with an on-chip Power Management Unit (PMU) that enhances energy efficiency. For example, high-speed PWM and UART modules can operate independently at different clock speeds, allowing developers to reduce power consumption without sacrificing performance.
The LPC2900 also delivers strong connectivity options, including dual CAN interfaces, dual LIN buses, a standard serial bus, and two ADCs. These features make it a great fit for applications such as engine control, CAN gateways, PLCs, industrial networks, in-car entertainment, and navigation systems.
Geoff Lees, General Manager of NXP's Microcontroller Division, said, “The growth of 32-bit ARM-based MCUs is now outpacing other architectures. The LPC2900 reinforces NXP’s leadership while complementing our existing LPC2000 and LPC3000 lines, offering customers the broadest selection of ARM-based MCUs in the industry.†He added, “The LPC2900 provides a system-level solution that enhances our ARM7TDMI and ARM926EJ-based MCUs.â€
Each of the three new devices features a simplified design with consistent peripherals and code compatibility. The LPC2917 and LPC2919 include a 32-bit memory controller that supports various static memory devices, including RAM, ROM, flash, burstROM, and external I/O. The system can support up to 768KB of on-chip flash and 80KB of SRAM. The 128-bit wide flash (wideFlash) allows reading four words at once, boosting performance compared to standard flash. The SRAM is divided into 16KB of TCM for data, 16KB for code, and 48KB of general-purpose SRAM.
Additionally, the integrated CAN 2.0B controller offers full CAN mode, three transmit buffers with automated prioritization for efficient gateway functions, and comprehensive filtering for global CAN acceptance. All devices use the standard ARM JTAG interface for tool compatibility, ensuring smooth integration with existing development environments.
