USB2229

Please consider this device

The USB2229 is a 5th Generation USB 2.0 composite device that provides an interface between a single USB Host port and all mainstream Flash Card Media interfaces as well as an IrDA controller. It is identical to the USB2230 without the support for xD-Picture Card™.

The USB2229 provides a single chip solution for the most prevalent options for transfer of digital pictures - popular flash memory cards and IrDA transfers from mobile phone cameras.

The device consists of a USB 2.0 device PHY and SIE, buffers, Fast 8051 microprocessor with expanded scratchpad, and program SRAM, and CF, MS, SM and SD controllers. The device can support up to 4 slot memory operation and has the card power MOSFETS integrated on chip.

Provision for external Flash Memory up to 128K bytes for program storage is provided.
