Table 4-12. I2C Addressing

I2C Address Bit Description
The first 4 bits of the device address are set to
1010, the next two are set by the A2 and A1
pins, the seventh bit, a16, is the most significant
internal address bit
The first 6 bits of the target address are set to
010000, the next bit is determined by the addr pin
of the IO expander
The first 6 bits of the target address are set to
010000, the next bit is determined by the addr pin
of the IO expander
The first three bits of the target address are 100,
the following four bits are determined by what is
hooked up to A1 and A0
The first three bits of the target address are 100,
the following four bits are determined by what is
hooked up to A1 and A0
Fixed value of 1001100 for part number
TMP411Ax
The first four bits of the target address are 1100,
the following three are determined by A2, A1, and
A0
