1 / 17 page TECHNICAL NOTE HIGH GRADE Specification HIGH RELIABILITY series SPI BUS Serial EEPROMs Supply voltage 2.5V~5.5V Operating temperature -40°C ~ +125°C type BR25H010-W, BR25H020-W, BR25H040-W, BR25H080-W, BR25H160-W, BR25H320-W ☆ : Under development ● 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.) At read action (5V) : 1.0mA (Typ.) At standby action (5V) : 0.1μA (Typ.) ● Address auto increment function at read action ● 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. ● SOP8, SOP-J8 Package ● Data at shipment Memory array: FFh, status register WPEN, BP1, BP0 : 0 ● Data kept for 40 years. ● Data rewrite up to 1,000,000times. ● BR25H series Capacity Bit format Type Power source voltage SOP8 SOP-J8 1Kbit 128×8 BR25H010-W 2.5~5.5V ● ● 2Kbit 256×8 BR25H020-W 2.5~5.5V ● ● 4Kbit 512×8 BR25H040-W 2.5~5.5V ● ● 8Kbit 1K×8 BR25H080-W 2.5~5.5V ● ● 16Kbit 2K×8 BR25H160-W 2.5~5.5V ● ● 32Kbit 4Kx8 BR25H320-W 2.5~5.5V ● ● Ver A.
