AT93C46 - 3-Wire Serial EEPROMs

Description

The AT93C46 provides 1024 bits of serial electrically erasable programmable read only memory (EEPROM) organized as 64 words of 16 bits each, when the ORG pin is connected to VCC and 128 words of 8 bits each when it is tied to ground.

Features

  • Medium-voltage and Standard-voltage Operation.
  • 2.7 (VCC = 2.7V to 5.5V).
  • User-selectable Internal Organization.
  • 1K: 128 x 8 or 64 x 16.
  • Three-wire Serial Interface.
  • 2 MHz Clock Rate (5V).
  • Self-timed Write Cycle (10 ms max).
  • High Reliability.
  • Endurance: 1 Million Write Cycles.
  • Data Retention: 100 Years.
  • 8-lead TSSOP and 8-lead JEDEC SOIC Packages 2.
