●Overview
●The LPC3180 is an ARM9-based microcontroller for embedded applications requiring high performance combined with low power dissipation. It achieves these objectives through the combination of NXP®"s state-of-the-art 90 nanometer technology with an ARM926EJ-S CPU core with a Vector Floating Point (VFP) coprocessor and a large array of standard peripherals including USB On-The-Go.
●The microcontroller can operate at over 200 MHz CPU frequency (about 220 MIPS per ARM Inc.). The ARM926EJ-S CPU incorporates a 5-stage pipeline and has a Harvard architecture with separate 32 kB instruction and data caches, a demand paged MMU, DSP instruction extensions with a single cycle MAC, and Jazelle Java bytecode execution hardware. A block diagram of the microcontroller is shown .
●Power optimization in this microcontroller is done through process and technology development (Intrinsic Power), and architectural means (Managed Power).
●The LPC3180 also incorporates an SDRAM interface, NAND flash interfaces, USB 2.0 full-speed interface, seven UARTs, two I²C-bus interfaces, two SPI ports, a Secure Digital (SD) interface, and a 10-bit ADC in addition to many other features.

●## Features
●Key features
● ARM926EJ-S processor with 32 kB instruction cache and 32 kB data cache, running at up to 208 MHz.
● 64 kB of SRAM.
● High-performance multi-layer AHB bus system provides a separate bus for CPU data and instruction fetch, two data buses for the DMA controller, and another for the USB controller.
● External memory interfaces: one supports DDR and SDR SDRAM, another supports single-level and multi-level NAND flash devices and can serve as an 8-bit parallel interface.
● General purpose DMA controller that can be used with the SD card and SPI interfaces, as well as for memory-to-memory transfers.
● USB 2.0 full-speed device, host (OHCI compliant), and OTG block. A dedicated PLL provides the 48 MHz USB clock.
● Multiple serial interfaces, including seven UARTs, two SPI controllers, and two single master I²C-bus interfaces.
● SD memory card interface.
● Up to 55 GPI, GPO, and GPIO pins. Includes 12 GPI pins, 24 GPO pins, and six GPIO pins.
● 10-bit ADC with input multiplexing from three pins.
● Real-Time Clock (RTC) with separate power supply and power domain, clocked by a dedicated 32 kHz oscillator. Includes a 128 byte scratch pad memory. The RTC may remain active when the rest of the chip is not powered.
● 32-bit general purpose high-speed timer with 16-bit pre-scaler with capture and compare capability.
● 32-bit millisecond timer driven from the RTC clock. Interrupts may be generated using two match registers.
● Watchdog timer.
● Two PWM blocks with an output rate up to 50 kHz.
● Keyboard scanner function provides automatic scanning of up to an 8 x 8 key matrix.
● Standard ARM test/debug interface for compatibility with existing tools.
● Emulation trace buffer with 2 k x 24-bit RAM allows trace via JTAG.
● On-chip crystal oscillator.
● Stop mode saves power, while allowing many peripheral functions to restart CPU activity.
● On-chip PLL allows CPU operation up to the maximum CPU rate without the need for a high frequency crystal.
● Boundary scan for simplified board testing.
