BU9832GUL-W
●Description
BU9832GUL-W is a serial EEPROM of SPI BUS interface method.
●Features
1) High speed clock action up to 5MHz (Max.)
2) Wait function by HOLD terminal.
3) Part or whole of memory arrays settable as read only memory area by program.
4) 1.8 ~ 5.5V single power source action most suitable for battery use.
5) Page write mode useful for initial value write at factory shipment.
6) For SPI bus interface (CPOL, CPHA) = (0, 0), (1, 1)
7) Auto erase and auto end function at data rewrite.
8) Low current consumption
At write action (5V)
: 1.5mA (Typ.)
At read action (5V)
: 1.0mA (Typ.)
At standby action (5V)
: 0.1µA (Typ.)
9) Address auto increment function at read action
10) Write mistake prevention function
Write prohibition at power on.
Write prohibition by command code (WRDI).
Write prohibition by WP pin.
Write prohibition block setting by status registers (BP1, BP0)
Write mistake prevention function at low voltage.
11) Data at shipment Memory array: FFh, status register WPEN, BP1, BP0 : 0
12) Data kept for 40 years.
13) Data rewrite up to 1,000,000times.
