Pin Descriptions
SDA
This pin is used to transfer addresses and data into
and out of the device, when the device is in the
bi-directional mode. In the transmit-only mode,
which only allows data to be read from the device,
data is also transferred on the SDA pin. This pin is
an open drain terminal, therefore the SDA bus
requires a pull-up resistor to VCC (typical 10k
for
100 Khz, 1k
for 400 Khz).
For normal data transfer in the bi-directional mode,
SDA is allowed to change only during SCL low.
Changes during SCL high are reserved for
indicating the START and STOP conditions.
SCL
This pin is the clock input for the bi-directional
mode, and is used to synchronize data transfer to
and from the device. It is also used as the signaling
input to
switch the device from the transmit only mode to
the bi-directional mode. It must remain high for the
chip to continue operation in the transmit only
mode.
VCLK
This pin is the clock input for the transmit only
mode. In the transmit only mode, each bit is
clocked out on the rising edge of this signal. In the
bi-directional mode, a high logic level is required on
this pin to enable write capability.
