Cost-effective, low-power microcontrollers deliver improved performance and greater ARM9 options

Built around an ARM968 core, LPC291x microcontrollers offer high performance with low power consumption. NXP’s LPC2917 and LPC2919 microcontrollers use a high-performance, 32-bit core that operates at up to 80MHz.

To simplify design, the two devices offer consistent peripherals and code compatibility. Integrated CAN 2.0B controllers offer full CAN mode for message reception, triple transmit buffers with automatic priority scheduling, and extensive global CAN-acceptance filtering for high-performance gateway functionality. Two 3V 8-channel, 10-bit ADCs can be synchronised with the on-board PWMs for motor control.

Multiple serial communication interfaces increase design flexibility, provide larger buffer size, and deliver higher processing power. There are two 16C550 UARTs with 16-byte transmit and receive FIFO depths, and three full-duplex Q-SPI interfaces with four slave- select lines.

On-chip memory resources include SRAM, Flash and two Tightly-Coupled Memories (TCMs): a 16kb Instruction TCM (ITCM) and a 16kb Data TCM (DTCM).

The LPC2917 and LPC2919 have 32-bit external memory controllers that support static memory- mapped devices. For fast interrupt response, an integrated Vectored Interrupt Controller (VIC) is included on each microcontroller. The LPC291x family is available in 144-pin LQFP packages with an operating temperature range from -40°C to 85°C.
