(128K)
●General Description
BR25S128GUZ-W is a 16K×8bit serial EEPROM of SPI BUS interface method.
●Features
High speed clock action up to 10MHz (Max.)
Wait function by HOLDB terminal
Part or whole of memory arrays settable as read only
memory area by program
1.7V to 5.5V single power source action most suitable
for battery use
64Byte page write mode useful for initial value write
at factory shipment
For SPI bus interface (CPOL, CPHA) = (0, 0), (1, 1)
Auto erase and auto end function at data rewrite
Low current consumption
¾ At write action (5V) : 1.5mA (Typ.)
¾ At read action (5V) : 1.0mA (Typ.)
¾ At standby action (5V) : 0.1μA (Typ.)
Address auto increment function at read action
Write mistake prevention function
¾ Write prohibition at power on
¾ Write prohibition by command code (WRDI)
¾ Write prohibition by WP pin
¾ Write prohibition block setting by status registers
(BP1, BP0)
¾ Write mistake prevention function at low voltage
Data kept for 40 years
Data rewrite up to 1,000,000 times
Data at shipment Memory array: FFh, status register
WPEN, BP1, BP0 : 0
