The R1EX25xxx Series is a Serial Peripheral Interface (SPI) EEPROM that offers high speed, low power consumption, and reliability.
It comes in 32k and 64k options and uses advanced MONOS memory technology and CMOS process.
The EEPROM has a 32-byte page programming function for faster write operations.
It operates on a single supply voltage of 1.8V to 5.5V and is compatible with the SPI bus.
The EEPROM has a clock frequency of 5MHz (2.5V to 5.5V) and 3MHz (1.8V to 5.5V) and has a low power consumption in standby and active modes.
It also has automatic page write, a write cycle time of 5ms, and an endurance of 106 erase/write cycles.
The EEPROM is available in small size packages and is lead-free.
The document also includes ordering information, pin arrangement, pin description, block diagram, absolute maximum ratings, DC operating conditions, DC characteristics, AC characteristics, timing waveforms, and pin function details.
