BR25S128GUZ-W_11

High Reliability Series Serial EEPROM Series WL-CSP EEPROMs family SPI BUS BR25S128GUZ-W ●Description BR25S128GUZ-W is a 16K×8bit serial EEPROM of SPI BUS interface method. ●Features 1) High speed clock action up to 10MHz (Max.) 2) Wait function by HOLDB terminal 3) Part or whole of memory arrays settable as read only memory area by program 4) 1.7～5.5V single power source action most suitable for battery use 5) 64Byte page write mode useful for initial value write at factory shipment 6) For SPI bus interface (CPOL, CPHA)=(0, 0), (1, 1) 7) Auto erase and auto end function at data rewrite 8) Low current consumption At write action (5.0V) : 1.5mA (Typ.) At read action (5.0V) : 1.0mA (Typ.) At standby action (5.0V) : 0.1μA (Typ.) 9) Address auto increment function at read action 10) Write mistake prevention function Write prohibition at power on Write prohibition by command code (WRDI) Write prohibition by WPB pin Write prohibition block setting by status registers (BP1, BP0) Write mistake prevention function at low voltage 11) VCSP35L2 Package 12) Data at shipment Memory array: FFh, status register WPEN, BP1, BP0 : 0 13) Data kept for 40 years 14) Data rewrite up to 1,000,000 times No.11001JBT06 www.rohm.com © 2011 ROHM Co., Ltd.
