●Description
□□□ BR25H
-W series is a serial EEPROM of SPI BUS interface method.
●Features
● High speed clock action up to 5MHz (Max.)
● Wait function by HOLDB terminal.
● Part or whole of memory arrays settable as read only memory area by program.
● 2.5～5.5V single power source action most suitable for battery use.
● Page write mode useful for initial value write at factory shipment.
● Highly reliable connection by Au pad and Au wire.
● For SPI bus interface (CPOL, CPHA)=(0, 0), (1, 1)
● Auto erase and auto end function at data rewrite.
● Low current consumption
At write action (5V) : 1.5mA (Typ.)
●Page write
