NXP 80-MHz, 32-bit
ARM968 microcontroller
LPC291x with CAN and LIN
High performance ARM968-based microcontroller with CAN and LIN
Built around an ARM968 core, this 32-bit microcontroller is optimized for automotive and industrial applications and fills the performance gap between ARM7TDMI and ARM926EJ technologies.
It offers high performance and very low power consumption, integrates CAN 2.0B and LIN 2.0 controllers, and is available in two package variants.

The NXP microcontrollers LPC2915, LPC2917, and LPC2919 use a high-performance, 32-bit ARM968 core that operates at up to 80 MHz. On-chip memory resources include two tightly coupled memories (TCMs), a 16-KB instruction TCM (ITCM) and a 16-KB data TCM (DTCM). The LPC2915 has
32 KB of SRAM, while the LPC2917 and LPC2919 have 48 KB. The LPC2915 and LPC2917 have 512 KB of Flash memory and the LPC2919 has 768 KB.
To simplify design, the three 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 highperformance gateway functionality.
