General Description
NM24C65U General Description
The NM24C65U is a 64K (65,536) bit serial interface CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory). This device fully conforms to the Extended I2C™ 2-wire protocol which uses Clock (SCL) and Data I/O (SDA) pins to synchronously clock data between the "master" (for example a microprocessor) and the "slave" (the EEPROM device). In addition, the serial interface allows a minimal pin count packaging designed to simplify PC board layout requirements and offers the designer a variety of low voltage and low power options.
NM24C65U incorporates a hardware "Write Protect" feature, by which the upper half of the memory can be disabled against programming by connecting the WP pin to VCC. This section of memory then effectively becomes a ROM (Read-Only Memory) and can no longer be programmed as long as WP pin is connected to VCC.
Fairchild EEPROMs are designed and tested for applications requiring high endurance, high reliability and low power consumption for a
