Pin Function Table
Description:
The Microchip Technology Inc. 93XX76A/B/C devices
are 8K bit, low-voltage, serial Electrically Erasable
PROMs (EEPROM). 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 and R oHS complian t.
