I2C bus interface
FDA803U

DS12497 Rev 2

I2C bus interface
Data transmission from microprocessor to the FDA803U and viceversa takes place through
the 2 wires I2C bus interface, consisting of the two lines SDA and SCL (pull-up resistors to
positive supply voltage must be connected).
When I2C bus is active any operating mode of the IC may be modified and the diagnostic
may be controlled and results read back.
The protocol used for the bus is depicted in Figure 69 and comprises:
a start condition (S)
a chip address byte (the LSB bit determines read/write transmission)
a subaddress byte
a sequence of data (N-bytes + acknowledge)
a stop condition (P)
Figure 69. I2C bus protocol description
1.
The I2C addresses are:
Address 1 = 1110000
Address 2 = 1110001
Address 3 = 1110010
Address 4 = 1110011
Address 5 = 1110100
Address 6 = 1110101
Address 7 = 1110110
Address 8 = 1110111
Description:
–
S = Start
–
R/W = '0' => Receive-Mode (Chip could be programmed by μP)
–
I = Auto increment; when 1, the address is automatically incremented for each
byte transferred
–
X: not used
–
A = Acknowledge
–
P = Stop
–
MAX CLOCK SPEED 400kbit/sec
