Word-selectable devices such as 1024 x 8-bit Organization A Devices (no ORG) the 93XX76C are dependent upon external logic levels 512 x 16-bit Organization B Devices (no ORG) driving the ORG pin to set word size. In the SOT-23 Program Enable Pin to Write-Protect the Entire package, the 93XX76A devices provide dedicated 8-bit Array (76C version only) memory organization, while the 93XX76B devices Self-Timed Erase/Write Cycles (including provide dedicated 16-bit memory organization. A Auto-Erase) Program Enable (PE) pin allows the user to write-protect the entire memory array. Advanced CMOS technology Automatic ERAL Before WRAL makes these devices ideal for low-power, nonvolatile Power-On/Off Data Protection Circuitry memory applications. The 93XX Series is available in Industry Standard 3-Wire Serial I/O standard packages including 8-lead PDIP and SOIC, Device Status Signal (Ready/Busy) and advanced packaging including 8-lead MSOP, 6-lead Sequential Read Function SOT-23, 8-lead 2x3 DFN and 8-lead TSSOP. All 1,000,000 Erase/Write Cycles packages are Pb-free (Matte Tin) finish.
