CXD3152R
Using the EEPROM
The CXD3152R can connect an external EEPROM which supports the I
2
C bus. Normally, read and write to
and from the EEPROM are performed from the PC master via the I
2
C bus to the slave EEPROM. Also, this IC
can automatically read the user-set register values during power-on by writing the addresses and setting
values for up to 64 registers in the EEPROM. (At this time this IC is the master device and the EEPROM is the
slave device.)
The serial EEPROM S-24C01B made by Seiko Instruments Co., Ltd. or equivalent product can be used as the
external EEPROM.
The external EEPROM load timing during power-on or register reset is shown below for when an EEPROM is
mounted and not mounted. The I
2
C bus is occupied by the EEPROM load at this period, so when using the I
2
C
bus, other communication by the master device is prohibited for the following times from the rising edge of
REGRESS.
