1.0 Product Overview
1.1 Overview
The PL2773 is a low-power single-chip SuperSpeed USB 3.0 and eSATA Combo to SATA II compliant
bridge IC controller. It is designed to perform seamless protocol transfer between the USB or eSATA
host PC and SATA interface storage devices like Hard Disk Drives, Optical Disk Drives, and
Solid-State Drives. SuperSpeed USB 3.0 has data transfer bandwidth of up to 5Gbps offering 10X
performance increase over Hi-Speed USB 2.0 (480Mbps) while still retaining backward compatibility
and interoperability with all USB2.0 and USB1.1 devices, hosts, and hubs. The PL2773 eSATA mode
connection (SATA Gen1/Gen2) provides transfer rate up to 3Gbps bandwidth. The PL2773 also
integrates a high performance 8-bit microcontroller which can be used to support versatile system
applications such as one button backup, power control, and other USB port features. The PL2773
chip is also implemented according to the USB Bulk-Only Mass Storage Class Specification v1.0.

4.0 External Configuration ROM
4.1 External Configuration ROM
The PL2773 uses external serial memory (EEPROM or Flash) to store the Vendor ID, Product ID,
Device Release Number (in device descriptor), Attributes and Max Power setting (in configuration
descriptor), String Descriptor and some chip operation mode configuration. The external firmware of
PL2773 is also stored in this memory and the maximum size is 46KB by SPI interface or 28KB by I2C
interface. After reset, the firmware in the external memory will be loaded into internal program SRAM.
Two types of serial interface are supported, the one is SPI (Serial Peripheral Interface) and the other
is I2C compatible interface. Both interfaces support master mode only. The PL2773 allows the
following possible configurations:
I2C Serial EEPROM: This option uses I2C serial EEPROM to store chip configuration data and
firmware. Firmware is stored in the EEPROM and will be loaded during system startup.
SPI Serial Flash: This is the recommended option. It behaves the same as the I2C serial memory
with this chip but the transfer speed of SPI interface is faster than I2C interface. The SPI interface
is a four-pin interface but this chip uses only three pins to communicate with. So the DI and DO
are shorted; or better short by a serial 240-ohm resistor.
4.2 Data Structure of External Serial Memory Content
The Configuration ROM is organized as follows:
Address
