<div class="indent">The LPC13xx devices are ARM Cortex-M3-based microcontrollers for embedded applications featuring a high level of integration and low power consumption. The ARM Cortex-M3 is a next generation core that offers system enhancements such as enhanced debug features and a higher level of support block integration.</div>
<div class="indent">The LPC13xx devices operate at CPU frequencies of up to 72MHz. The ARM Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals. The ARM Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branching.</div>
<div class="indent">The peripheral complement of the LPC13xx includes up to 32KB of flash memory, up to 8KB of data memory, USB Device (LPC134x only), one Fast-mode plus (Fm+) I<sup>2</sup>C interface, one UART, four general purpose timers, and up to 42 general purpose I/O pins.  </div>
