BRCA016GWZ-W (16Kbit)
General Description
BRCA016GWZ-W series is a serial EEPROM of I
2
C BUS Interface Method.
Features
■
■
■
■
■
■
■
Completely conforming to the world standard I
2
C BUS. All controls available by 2 ports of serial clock (SCL)
and serial data (SDA)
Other devices than EEPROM can be connected to the same port, saving microcontroller port.
1.7V to 3.6V Single Power Source Operation most suitable for battery use.
Possible FAST MODE 400KHz operation
Page Write Mode useful for initial value write at factory shipment.
Self-timed Programming Cycle
Low Current Consumption
At Write Operation (5V)
: 0.5mA (Typ)
At Read Operation (5V)
: 0.2mA (Typ)
At Standby Operation (5V)
: 0.1μA (Typ)
Prevention of Write Mistake
Write (write protect) function added
Prevention of write mistake at low voltage
UCSP30L1 Compact Package

○At
write execution, in the area from the D0 taken clock rise of the first DATA(1),
to t
WR
, set WP= 'LOW'.
○By
setting WP "HIGH" in the area, write can be cancelled.
When it is set WP = 'HIGH' during t
WR
, write is forcibly ended, and data of
address under access is not guaranteed, therefore write it once again.
