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.)
