1. general description 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 philips' 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 in figure 1 . 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 ?ash interfaces, usb 2.0 full-speed interface, seven uarts, two i 2 c-bus interfaces, two spi ports, a secure digital (sd) interface, and a 10-bit adc in addition to many other features. 2. features 2.1 key features n arm926ej-s processor with 32 kb instruction cache and 32 kb data cache, running at up to 208 mhz. n 64 kb of sram. n 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. n external memory interfaces: one supports ddr and sdr sdram, another supports single-level and multi-level nand ?ash devices and can serve as an 8-bit parallel interface. n general purpose dma controller that can be used with the sd card and spi interfaces, as well as for memory-to-memory transfers. n usb 2.0 full-speed device, host (ohci compliant), and otg block. a dedicated pll provides the 48 mhz usb clock. n multiple serial interfaces, including seven uarts, two spi controllers, and two single master i 2 c-bus interfaces. n sd memory card interface.
