SE97B
DDR memory module temp sensor with integrated SPD
7.   Functional description
7.1   Serial bus interface
The SE97B communicates with a host controller by means of the 2-wire serial bus
(I
2
C-bus/SMBus) that consists of a serial clock (SCL) and serial data (SDA) signals. The
device supports SMBus, I
2
C-bus Standard-mode and Fast-mode. The I
2
C-bus standard
speed is defined to have bus speeds from 0 Hz to 100 kHz, I
2
C-bus fast speed from 0 Hz
to 400 kHz, and the SMBus is from 10 kHz to 100 kHz. The host or bus master generates
the SCL signal, and the SE97B uses the SCL signal to receive or send data on the SDA
line. Data transfer is serial, bidirectional, and is one byte at a time with the Most Significant
Bit (MSB) transferred first. Since SCL and SDA are open-drain, pull-up resistors must be
installed on these pins.
7.2   Slave address
The SE97B uses a 4-bit fixed and 3-bit programmable (A0, A1 and A2) 7-bit slave address
that allows a total of eight devices to coexist on the same bus. The A0, A1 and A2 pins are
pulled LOW internally. The A0 pin is also overvoltage tolerant supporting 10 V software
write protect. When it is driven higher than 7.0 V, writing a special command would put the
EEPROM in reversible write protect mode (see Section 7.10.2 
Memory Protection

).
Each pin is sampled at the start of each I
2
C-bus/SMBus access. The temperature
sensors fixed address is 0011b. The EEPROMs fixed address for the normal EEPROM
read/write is 1010b, and for EEPROM software protection command is 0110b. Refer to
Figure 3
