NXP Semiconductors LPC1776
The LPC178x/7x is an ARM Cortex-M3 based microcontroller for embedded applications requiring a high level of integration and low power dissipation. The Cortex-M3 is a next generation core that offers better performance than the ARM7 at the same clock rate and other system enhancements such as modernized debug features and a higher level of support block integration. The Cortex-M3 CPU incorporates a 3-stage pipeline and has a Harvard architecture with separate local instruction and data buses, as well as a third bus with slightly lower performance for peripherals.| Part No. | LPC1776 |

FEATURES AND BENEFITS
● Functional replacement for the LPC23xx and LPC24xx family devices.● System:
● ARM Cortex-M3 processor, running at frequencies of up to 120 MHz. A Memory Protection Unit (MPU) supporting eight regions is included.
● ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).
● Multilayer AHB matrix interconnect provides a separate bus for each AHB master. AHB masters include the CPU,USB, Ethernet, and the General Purpose DMA controller. This interconnect provides communication with no arbitration delays unless two masters attempt to access the same slave at the same time.
● Split APB bus allows for higher throughput with fewer stalls between the CPU and DMA. A single level of write buffering allows the CPU to continue without waiting for completion of APB writes if the APB was not already busy.
