The device consists of a USB 2.0 PHY and SIE, buffers, Fast 8051 microprocessor with expanded scratchpad and 768 of program SRAM, internal 48 KB program ROM, and an ATA-66 compatible interface. Provisions for optional external Flash Memory up to 64K bytes for program storage is provided. A serial EEPROM which can be modified via USB from the host provides unique VID/PID/Serial numbers, as well as optional configuration information. Internal 768 Bytes of scratchpad SRAM are also provided.. This internal SRAM can also be used for program storage to implement program upgrade via USB download to external “boot block” Flash program memory, if desired. Seven GPIO pins are provided for controlling external power control elements and sensing specialized drive functions. Provisions are made to allow dynamic attach and re-attach to the USB bus to allow hot swap of drives to be implemented.

This pin can be connected to one terminal of the crystal or can be connected to an external 12Mhz clock when a crystal is not used. 12Mhz Crystal This is the other terminal of the crystal, or left open when an external clock source is used to drive XTAL1/CLKIN. It may not be used to drive any external circuitry other than the crystal circuit. This pin produces a 30Mhz clock signal independent of the processor clock divider. It is held inactive and low whenever the internal processor clock is stopped or is being obtained from the ring oscillator. When left unconnected or tied high, the USB97C202 uses the internal ROM for program execution. When tied low, an external program memory should be connected to the memory/data bus. The state of this pin latched internally on the rising edge of nRESET.

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.
