ROHM BR25H020FJ-2CE2

BR25H020-2C is a serial EEPROM of SPI BUS interface method.

• 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.
• 2.5V to 5.5V single power source action most suitable for battery use.
• Page write mode useful for initial value write at factory shipment.
• For SPI bus interface (CPOL, CPHA)=(0, 0), (1, 1)
• Self-timed programming cycle.
• Low Supply Current At write operation (5V) : 1.0mA (Typ.) At read operation (5V) : 1.0mA (Typ.) At standby operation (5V) : 0.1μA (Typ.)
• Address auto increment function at read operation
• Prevention of write mistake
• 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).
• Prevention of write mistake at low voltage.
• MSOP8, TSSOP-B8, SOP8, SOP-J8 Package
• Data at shipment Memory array: FFh, status register BP1, BP0 : 0
• More than 100 years data retention.
• More than 1 million write cycles.
• AEC-Q100 Qualified.
• This IC has status registers. The status registers are of 8 bits and express the following parameters. BP0 and BP1 can be set by write status register command. These 2 bits are memorized into the EEPROM, therefore are valid even when power source is turned off.
• Number of data rewrite times and data hold time are same as characteristics of the EEPROM.
• WEN can be set by write enable command and write disable command. WEN becomes write disable status when power source is turned off.
• R/B is for write confirmation, therefore cannot be set externally.
• The value of status register can be read by read status command.
