In July 1998, Fudan Microelectronics was jointly founded by Fudan University's "National Key Laboratory of ASICs and Systems", Shanghai Commercial Investment Company and a group of entrepreneurs who dreamed of creating the best integrated circuit design company (chip design) in China. Since its establishment, the company has successfully established a pivotal position in the domestic integrated circuit design industry. The company was listed in Hong Kong on August 4, 2000 (stock code: 1385), becoming the first listed company in the domestic integrated circuit design industry. Today, Fudan Microelectronics has grown from more than 10 entrepreneurs to a company with more than 600 employees, with users all over the world. The company has attracted the attention of domestic and foreign peers with its excellent management, good development potential and outstanding performance. In 2011, Fudan Microelectronics was selected as the "Best Small and Medium-sized Listed Company" by the editors of Forbes Asia magazine.

FM93C66A Three-wire Serial EEPROM
Features
FM93C66A provides 4k bits of serial electrically erasable programmable read-only memory EEPROM),organized as 256 words of 16 bits each (when the ORG pin is connected to VCC), and 512 words of 8 bits each (when the ORG pin is connected to ground).
The FM93C66A is enabled through the Chip Select pin (CS) and accessed via a three-wire serial interface consisting of Data Input (DI). Data Output (DO), and Serial Clock (SK). Upon receiving a read instruction at DI, the address is decoded and the data is clocked out serially on the data output pin DO. The write cycle is completely self-timed and no separate erase cycle is required before write. The write cycle is only enabled when the part is in the Erase/Write Enable State. When CS is brought "high" following the initiation of a write cycle The DO pin outputs the Ready/ Busy status of the part.
The device is the best choice for use in many industrial and commercial applications where low-power and low-voltage operations are essential.
