Description:

The Microchip Technology Inc. 93XX76A/B/C devices

are 8Kbit, 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 (Matte Tin) finish.
