Serial Peripheral Interface 512K EEPROM (64-Kword × 8-bit) Electrically Erasable and Programmable Read Only Memory
REJ03C0372-0001 Preliminary Rev.0.01 Dec.19.2008
Description
R1EX25xxx Series is the Serial Peripheral Interface compatible (SPI) EEPROM (Electrically Erasable and Programmable ROM). It realizes high speed, low power consumption and a high level of reliability by employing advanced MONOS memory technology and CMOS process and low voltage circuitry technology. It also has a 128byte page programming function to make its write operation faster. www.DataSheet4U.com Note: Renesas Technology's serial EEPROMs are authorized for using consumer applications such as cellular phones, camcorders and audio equipments. Therefore, please contact Renesas Technology's sales office before using industrial applications such as automotive systems, embedded controllers and meters.
