FT93C46/56/66 Series

3-Wire Serial EEPROM 1K, 2K and 4Kbit (8-Bit or 16-Bit Wide)

Fremont Micro Devices Ltd

The FT93C46/56/66 series are 1024/2048/4096 bits of serial Electrical Erasable and Programmable Read Only Memory, commonly known as EEPROM. They are organized as 64/128/256 words of 16 bits each when the ORG pin is connected to VCC (or unconnected) and 128/256/512 words of 8 bits (1 byte) each when the ORG pin is tied to ground. The devices are fabricated with proprietary advanced CMOS process for low power and low voltage applications.
