SPI BUS EEPROM
BR25Lxxx-W Series
(1K 2K 4K 8K 16K 32K 64K)
●General Description
BR25Lxxx-W series is a serial EEPROM of SPI BUS interface method.
●Packages W(Typ.) x D(Typ.) x H(Max.)
●Features
High speed clock action up to 5MHz (Max.)
Wait function by HOLD terminal
Part or whole of memory arrays settable as read
only memory area by program
1.8V to 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
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 at shipment Memory array : FFh, status
register WPEN, BP1, BP0 : 0
Data kept for 40 years
Data rewrite up to 1,000,000 times
