—Internal RAM, which is downloaded via USB

—Internal RAM, which is loaded from EEPROM

—External memory device (**8 pin package

• Four programmable BULK/INTERRUPT/

ISOCHRONOUS endpoints

—Buffering options: double, triple and quad

• *- or **-bit external data interface

•GPIF

—Allows direct connection to most parallel interface

—Programmable waveform descriptors and configu-

ration registers to define waveforms
