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 high-
performance gateway functionality.
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 LPC2917 and LPC2919 are also equipped with dual LIN 2.0
master controllers.
The two 3V 8-channel, 10-bit ADCs can be synchronized with
the PWMs, making them ideal for Motor Control.
Multiple serial communications 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.
There are four 32-bit timers with capture/match channels for
pulse measurements, four six-channel, 32-bit PWMs, and a
Watchdog timer. A CPU clock, operating at a maximum of 80
MHz, is available from the on-chip phase-locked loop (PLL).
The LPC2917 and LPC2919 have 32-bit external memory
controllers that support static memory-mapped devices,
including RAM, ROM, Flash, burst ROM, and external I/O
devices. For fast interrupt response, an integrated vectored
interrupt controller (VIC) is included on each microcontroller.
Also, for compatibility with existing tools, each device uses
the standard ARM test/debug JTAG interface. The family is
available in 100- and 144-pin LQFP packages. There are up
to 108 GPIO, each tolerant to 5 V. The operating temperature
range is -40 to +85 °C.
