What are the different between the MCU cpu and MPU cpu

Some ARM CPU are called MCU,but others are called MPU。How to distinguishing them?
USB: Different Host Different Speed. Why? -LPC2148

I'm using an LPC2148 with a WINUSB driver in a simple data acquisition application. The host sends a request for data using a control transfer, and the device responds with a 900 byte block of data using...
