Description:
• Low-power CMOS technology
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 RoHS compliant.
• ORG pin to select word size for ‘76C’ version
• 1024 x 8-bit organization ‘A’ devices (no ORG)
• 512 x 16-bit organization ‘B’ devices (no ORG)
• Program Enable pin to write-protect the entire
array (‘76C’ version only)
• Self-timed erase/write cycles (including
auto-erase)
• Automatic ERAL before WRAL
• Power-on/off data protection circuitry
• Industry standard 3-wire serial I/O
• Device Status signal (Ready/Busy)
• Sequential read function
• 1,000,000 E/W cycles
• Data retention > 200 years
