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_).
