The 93C46 device from Microchip Technology Inc. is a 1Kbit low-voltage serial Electrically Erasable PROMs (EEPROM). To set word size, word-selectable devices like the 93AA46C, 93LC46C, or 93C46 C rely on external logic levels driving the ORG pin. The 93AA46A, 93LC46A, or 93C46A devices provide dedicated 8-bit communication, whereas the 93AA46B, 93LC46B, and 93C46 B devices provide dedicated 16-bit communication. These devices are suited for low-power, nonvolatile memory applications because of advanced CMOS technology. Standard packages, such as 8-lead PDIP and SOIC , and advanced packages, such as 8-lead MSOP, 6-lead SOT-23, 8-lead 2x3 DFN/TDFN, and 8-lead TSSOP, are available for the complete 93XX Series. Pb-free (Matte Tin) finish on all packages.
The Pinout of 93C46 is shown as follows.
