93C46WP is 1Kbit, MICROWIRE Serial Access EEPROM. These electrically erasable programmable memory (EEPROM) devices are accessed through a Serial Data Input (D) and Serial Data Output (Q)
using the MICROWIRE bus protocol.

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. These devices are available in standard 8-lead PDIP, 8-lead JEDEC SOIC and 8-lead TSSOP packages. Our extended VCC range (1.8V to 5.5V) devices enables wide spectrum of applications.
