Lpc2000

The LPC3180 is the industry's first 90nm ARM9-based microcontroller. 
The new 32-bit MCU provides high performance with low power 
dissipation, and is the only ARM9 microcontroller that provides a 
vector floating-point co-processor and integrated USB On-The-Go, as 
well as the ability to operate in ultra-low-power mode down to 0.9V. 
With speeds of up to 200 MHz, the LPC3180 is ideal for a wide range 
of high-precision applications such as point-of-sale (POS) 
equipment, medical and industrial devices, global positioning 
systems (GPS), and robotics. 

The LPC3180 is the first microcontroller available in the LPC3000 
family, which is based on the popular, high-performance ARM926EJ-S 
core. The on-board MMU supports major operating systems, including 
Linux which is the leading major embedded OS. The on-chip Java byte-
code co-processor provides for basic security and authentication 
applications. 

The LPC3180 is the only ARM9 microcontroller on the market today 
that offers a hardware vector floating-point unit for speed and 
efficiency. The LPC3180 is the first ARM9 MCU to offer USB On-The-Go 
(OTG) integrated with full host capability for direct connection to 
PDAs, smart-card readers, and printers. The large array of 
peripherals available on-chip also include 7 UARTs, SPI, I2C, a real-
time clock with a separate power domain, and NAND Flash and DDR 
memory controllers. 

Flexible power management allows high peak performance, especially 
for floating-point calculations, and allows shutting down the core 
power domain while retaining Real-Time Clock and wake-up 
functionality. The hardware floating-point co-processor speeds up 
typical calculations by a factor of 4 to 5 in scalar mode and much 
more in optimized vector mode.
