Introduction
1.4. What is USBizi
USBizi chip -pronounced USB easy- is a headless .NET Micro
Framework system based on LPC2388\LPC2387 chipsets. It is basically
a subset of Embedded Master which provides many of the great
features Embedded Master offers, with everything implemented on a
single chip. This is the smallest and lowest cost Micro Framework
device that still implements unique features like USB host.
Its limitations include reduced Flash and RAM size than Embedded
Master and no TCP/IP nor LCD/Graphics libraries are included. However, an LCD can be
connected and controlled using some of the many GPIOs available or SPI.
Comparison between Embedded Master and USBizi

USBizi chipset is available in two packages LQFP100 and LQFP144 . LQFP100 chipset is
identical to the LQFP144 pin version except that it doesn't contain a USB host. USB
device is still available and works exactly the same.
