Description
The ADJD-S311-CR999 is a cost effective, 4 channels
(RGB+CLEAR) digital output sensor in miniature surface-
mount package with a mere size of 2.2 x 2.2 x 0.76mm.
It is a CMOS IC with integrated RGB filters and analog-
to-digital converter front end. This device is designed to
cater for wide dynamic range of illumination level and
is ideal for applications like portable or mobile devices,
which demand higher integration, smaller size and low
power consumption. Sensitivity control is performed by
the serial interface and can be optimized individually for
the different color channel. The sensor can also be used
in conjunction with a white LED for reflective color man-
agement.

ESD Protection Diode Turn-On During Power-Up and
Power-Down
A particular power-up and power-down sequence must
be used to prevent any ESD diode from turning on in-
advertently. The figure above describes the sequence. In
general, AVDD and DVDD should power-up and power-
down together to prevent ESD diodes from turning on
inadvertently. During this period, no voltage should be
applied to the IO’s for the same reason.
Ground Connection
AGND and DGND must both be set to 0V and preferably
star-connected to a central power source as shown in
the application diagram. A potential difference between
AGND and DGND may cause the ESD diodes to turn on
inadvertently.

Description
The programming interface to the ADJD-S311 is a 2-wire serial bus. The bus consists of a serial clock (SCL) and a serial
data (SDA) line. The SDA line is bi-directional on ADJD-S311 and must be connected through a pull-up resistor to the
positive power supply. When the bus is free, both lines are HIGH.
The 2-wire serial bus on ADJD-S311 requires one device to act as a master while all other devices must be slaves. A
master is a device that initiates a data transfer on the bus, generates the clock signal and terminates the data transfer
while a device addressed by the master is called a slave. Slaves are identified by unique device addresses.
Both master and slave can act as a transmitter or a receiver but the master controls the direction for data transfer. A
transmitter is a device that sends data to the bus and a receiver is a device that receives data from the bus.
The ADJD-S311 serial bus interface always operates as a slave transceiver with a data transfer rate of up to 100kbit/s.
START/STOP Condition
The master initiates and terminates all serial data transfers. To begin a serial data transfer, the master must send a
unique signal to the bus called a START condition. This is defined as a HIGH to LOW transition on the SDA line while
SCL is HIGH.
The master terminates the serial data transfer by sending another unique signal to the bus called a STOP condition.
This is defined as a LOW to HIGH transition on the SDA line while SCL is HIGH.
The bus is considered to be busy after a START (S) condition. It will be considered free a certain time after the STOP (P)
condition. The bus stays busy if a repeated START (Sr) is sent instead of a STOP condition.
The START and repeated START conditions are functionally identical. See figure 3.

Figure 4. Data Bit Transfer

SCL

Data Transfer
The master initiates data transfer after a START condition. Data is transferred in bits with the master generating one
clock pulse for each bit sent. For a data bit to be valid, the SDA data line must be stable during the HIGH period of the
SCL clock line. Only during the LOW period of the SCL clock line can the SDA data line change state to either HIGH or
LOW.
7
A complete data transfer is 8-bits long or 1-byte. Each byte is sent most significant bit (MSB) first followed by an ac-
knowledge or not acknowledge bit. Each data transfer can send an unlimited number of bytes (depending on the data
format).
Figure 6. Data Bit Synchronization
Figure 5. Data Byte Transfer
The SCL clock line synchronizes the serial data transmission on the SDA data line. It is always generated by the master.
The frequency of the SCL clock line may vary throughout the transmission as long as it still meets the minimum timing
requirements.
The master by default drives the SDA data line. The slave drives the SDA data line only when sending an acknowledge
bit after the master writes data to the slave or when the master requests the slave to send data.
The SDA data line driven by the master may be implemented on the negative edge of the SCL clock line. The master
may sample data driven by the slave on the positive edge of the SCL clock line. Figure shows an example of a master
implementation and how the SCL clock line and SDA data line can be synchronized.
Acknowledge/Not acknowledge
The receiver must always acknowledge each byte sent in a data transfer. In the case of the slave-receiver and master-
transmitter, if the slave-receiver does not send an acknowledge bit, the master-transmitter can either STOP the transfer
or generate a repeated START to start a new transfer.

In the case of the master-receiver and slave-transmitter, the master generates a not acknowledge to signal the end of
the data transfer to the slave-transmitter. The master can then send a STOP or repeated START condition to begin a
new data transfer.
In all cases, the master generates the acknowledge or not acknowledge SCL clock pulse.

Addressing
Each slave device on the serial bus needs to have a unique address. This is the first byte that is sent by the master-trans-
mitter after the START condition. The address is defined as the first seven bits of the first byte.
The eighth bit or least significant bit (LSB) determines the direction of data transfer. A ‘one’ in the LSB of the first byte
indicates that the master will read data from the addressed slave (master-receiver and slave-transmitter). A ‘zero in this
position indicates that the master will write data to the addressed slave (master-transmitter and slave-receiver).
A device whose address matches the address sent by the master will respond with an acknowledge for the first byte
and set itself up as a slave-transmitter or slave-receiver depending on the LSB of the first byte.
The slave address on ADJD-S311 is 0x74 (7-bits).

Data format
ADJD-S311 uses a register-based programming architecture. Each register has a unique address and controls a specific
function inside the chip.
To write to a register, the master first generates a START condition. Then it sends the slave address for the device it
wants to communicate with. The least significant bit (LSB) of the slave address must indicate that the master wants to
write to the slave. The addressed device will then acknowledge the master.
The master writes the register address it wants to access and waits for the slave to acknowledge. The master then
writes the new register data. Once the slave acknowledges, the master generates a STOP condition to end the data
transfer.
Figure 10. Register Byte Write Protocol
To read from a register, the master first generates a START condition. Then it sends the slave address for the device it
wants to communicate with. The least significant bit (LSB) of the slave address must indicate that the master wants to
write to the slave. The addressed device will then acknowledge the master.
The master writes the register address it wants to access and waits for the slave to acknowledge. The master then
generates a repeated START condition and resends the slave address sent previously. The least significant bit (LSB) of
the slave address must indicate that the master wants to read from the slave. The addressed device will then acknowl-
edge the master.
The master reads the register data sent by the slave and sends a no acknowledge signal to stop reading. The master
then generates a STOP condition to end the data transfer.

Setup Value for Number of Integration Time Slot
The following value can be written to each of the integra-
tion time registers to adjust the gain of the sensor. The
default value after reset for these registers is 00H. These
registers control the number of integration time selected
for each channel. The integration time slot can be varied
from 00H to FFFH. More integration time slot will give
higher sensitivity.
Setup Value for Number of Capacitor
The following value can be written to each of the
capacitor registers to adjust the gain of the sensor. The
default value after reset for these registers is 0FH. These
registers control the number of capacitors selected for
each channel. The maximum selectable capacitor is
16 with the registers starting from 0 (i.e. 0 to 15). Less
capacitor will give higher sensitivity.
