Word-selectable devices such as 2048 x 8-bit organization A devices (no ORG) the 93XX86C are dependent upon external logic 1024 x 16-bit organization B devices (no ORG) levels driving the ORG pin to set word size. In the Program Enable pin to write-protect the entire SOT-23 package, the 93XX86A devices provide array (86C version only) dedicated 8-bit memory organization, while the Self-timed erase/write cycles (including 93XX86B devices provide dedicated 16-bit memory auto-erase) organization. A Program Enable (PE) pin allows the user to write-protect the entire memory array. Automatic ERAL before WRAL Advanced CMOS technology makes these devices Power-on/off data protection circuitry ideal for low-power, nonvolatile memory applications. Industry standard 3-wire serial I/O The entire 93XX Series is available in standard Device Status signal (Ready/Busy) packages including 8-lead PDIP and SOIC, and Sequential read function advanced packaging including 8-lead MSOP, 6-lead 1,000,000 E/W cycles SOT-23, 8-lead 2x3 DFN and 8-lead TSSOP. Pb-free (Pure Matte Sn) finish is available.
