Word-selectable devices such as the 93XX76C are dependent upon external logic levels driving the ORG pin to set word size. In the SOT-23 package, the 93XX76A devices provide dedicated 8-bit memory organization, while the 93XX76B devices provide dedicated 16-bit memory organization. A Program Enable (PE) pin allows the user to write-protect the entire memory array. Advanced CMOS technology makes these devices ideal for low-power, nonvolatile memory applications. The 93XX Series is available in standard packages including 8-lead PDIP and SOIC, and advanced packaging including 8-lead MSOP, 6-lead SOT-23, 8-lead 2x3 DFN and 8-lead TSSOP. All packages are Pb-free (Matte Tin) finish.
