1 INTRODUCTION
The ST72681 is a USB 2.0 high-speed Flash Drive
controller. The USB 2.0 high-speed interface in-
cluding PHY and function supports USB 2.0 Mass
Storage Device Class.
The Mass Storage Controller Interface combined
with the Reed-Solomon Encoder/Decoder on-the-
fly correction (4-byte on 512-byte data blocks) pro-
vides a flexible, high transfer rate solution for inter-
facing a wide of range NAND Flash memory de-
vice types.
The internal 60 MHz PLL driven by the 12MHz os-
cillator is used to generate the 480MHz frequency
for the USB 2.0 PHY.
The ST7 8-bit CPU runs the application program
from the internal ROM and RAM. USB data and
patch code are stored in internal RAM.
I/O ports provide functions for EEPROM connec-
tion, LEDs and write protect switch control.
The internal 3.3V to 1.8V voltage regulator pro-
vides the 1.8V supply voltage to the digital part of
the circuit.
