Word-selectable devices such as RoHS Compliant the 93AA46C, 93LC46C or 93C46C are dependent Temperature Ranges Supported: upon external logic levels driving the ORG pin to set - Industrial (I) -40C to +85C word size. For dedicated 8-bit communication, the - Automotive (E) -40C to +125C 93AA46A, 93LC46A or 93C46A devices are available, while the 93AA46B, 93LC46B and 93C46B devices provide dedicated 16-bit communication. Advanced CMOS technology makes these devices ideal for low- power, nonvolatile memory applications. The entire 93XX Series is available in standard packages includ- ing 8-lead PDIP and SOIC, and advanced packaging including 8-lead MSOP, 6-lead SOT-23, 8-lead 2x3 DFN/TDFN and 8-lead TSSOP. All packages are Pb-free (Matte Tin) finish. 2002-2013 Microchip Technology Inc.
