*Stresses above the specified parameters could cause permanent damage to the device. This is a stress rating only and functional operation of the device at any other condition above those indicated in the operation sections of this specification is not implied.

Note: When powering this device from laboratory or system power supplies, it is important that the Absolute Maximum Ratings not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on their outputs when the AC power is switched on or off. In addition, voltage transients on the AC power line may appear on the DC output. When this possibility exists, it is suggested that a clamp circuit be used.

The USB97C210 is a USB2.0 Bulk Only Mass Storage Class Peripheral Controller intended for supporting CompactFlash (CF) in True IDE Mode only, SmartMedia (SM/XD), Memory Stick (MS/MSPro), Secure Digital (SD) and MultiMediaCard (MMC) flash memory devices. The  USB97C210 provides a single chip solution for the most popular flash memory cards in the market.

The USB97C210 consists of a USB 2.0 PHY and SIE, buffers, Fast 8051 microprocessor with expanded scratchpad, and program SRAM, and CF, MS, SM and SD controllers. The SD controller supports both SD and MMC devices. The Memory Stick controller supports MS, HS MS and MSPro. The CF controller supports CF and CF form factor ATA drives. The Smart Media controller supports SM, XD, and single NAND flash devices.
* Provisions for external Flash Memory up to 64K bytes for program storage is provided.
* 12K bytes of scratchpad SRAM and 768Bytes of program SRAM are also provided.

Sixteen GPIO pins are for the 128-pin device. Provisions are made to allow hot swap of flash media to be implemented.
The USB97C210 supports the insertion one each of all 4 major types of cards (CF, SM/XD/Nand, MS/MSPro, MMC/SD) simultaneously.
