Application Scenarios & Design Considerations

4Kbit, 2Kbit and 1Kbit (16-bit wide) MICROWIRE Serial Access EEPROM with Block Protection

Alternative Part Number

  • AT93C66A-SSHM-T --: Same 4Kbit Microwire serial EEPROM with identical 93C66 organization and SPI-like interface, widely available and pin-compatible in SOIC-8.
  • CAT93C66VI-GT3 --: Direct 4Kbit Microwire EEPROM equivalent to the 93C66 family, same 8-pin SOIC footprint and 2.5-5.5V supply range.
  • BR93L66RF-WE2 --: 4Kbit Microwire serial EEPROM with matching 93C66 command set and SOIC-8 package, suitable drop-in replacement for the M93S66.
