Application Scenarios & Design Considerations

5 Volt, Byte Alterable E2PROM

Alternative Part Number

  • AT28C64B-15JU --: 64Kbit parallel EEPROM with similar pinout and access time, widely available and a common drop-in replacement for X28HC64 devices.
  • M28C64-15N6 --: 64Kbit parallel EEPROM in the same family class with comparable 70-150ns access timing and compatible JEDEC pinout.
  • NM28C64-15 --: 64Kbit parallel EEPROM offering equivalent organization and timing, suitable as a functional substitute for the X28HC64J-70.
  • AT28C64B-15JC --: 64K (8K x 8) parallel EEPROM in a PLCC package, functionally equivalent to the X28HC64 with compatible pinout and access timing suitable for most 70ns applications.
  • M28C64-15BS6 --: 8K x 8 parallel EEPROM with similar organization and interface; a common drop-in style replacement for 28C64-class devices in PLCC packages.
  • NM28C64Q-15 --: 64Kbit parallel EEPROM offering the same memory density and parallel interface, usable as a functional substitute where exact timing tolerance allows.
