Features

USB Host Interface supports USB V1.1 at 12Mbps, and is an alternative to the PC Card host interface.
New start up modes allow the PCMCIA Card Information Structure to be initialized from a serial EEPROM. This allows firmware to be downloaded from the host, eliminating the parallel Flash memory device.
Firmware can be loaded from serial Flash memory.
Direct attachment to a typical x16 SRAM using five control signals (RAMCS_, MOE_, MWEL_, MLBE_, and MUBE_).
