R1EX24512BSAS0A

R1EX24512BSAS0A R1EX24512BTAS0A Two-wire serial interface 512k EEPROM (64-kword × 8-bit) Preliminary Datasheet R10DS0025EJ0001 Rev.0.01 Sep, 01, 2010 Description R1EX24xxx series are two-wire serial interface EEPROM (Electrically Erasable and Programmable ROM). They realize 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. They also have a 128-byte page programming function to make their write operation faster. Note: Renesas Electronics’ serial EEPROM are authorized for using consumer applications such as cellular phone, camcorders, audio equipment. Therefore, please contact Renesas Electronics’ sales office before using industrial applications such as automotive systems, embedded controllers, and meters. Features Single supply: 1.8 V to 5.5 V Two-wire serial interface (I2C serial bus) Clock frequency: 1 MHz (2.5 V to 5.5 V) / 400 kHz (1.8 V to 5.5 V) Power dissipation:  Standby: 2 µA (max)  Active (Read): 1 mA (max)  Active (Write): 5 mA (max) Automatic page write: 128-byte/page Write cycle time: 5 ms Endurance: 1,000k Cycles @25°C Data retention: 100 Years @25°C Small size packages: SOP-8pin , TSSOP 8-pin Shipping tape and reel  SOP 8-pin: 2,500 IC/reel  TSSOP 8-pin: 3,000 IC/reel Temperature range: −40 to +85°C Lead free products.
