Programming the
MAX7428/MAX7430/MAX7432A
An address sequence precedes a write or read opera-
tion to determine with which device to communicate. If
the address transmitted in this mode matches with a
device’s address, the device and P can initiate data
transfer. When entering the four address bits, ensure
that the LSB is entered first. The following is the com-
mand sequence and timing diagram (Figure 6) for an
address sequence.
Use a write sequence to load data into the data register
of the device. It must follow an address sequence.
Transmit a minimum of eight data bits for the MAX7428,
16 data bits for the MAX7430, or 24 data bits for the
MAX7432A to make this transaction valid starting with
the LSB first. The last 8/16/24 data bits are used if more
than 8/16/24 bits are loaded into the register. The fol-
lowing is the command sequence and timing diagram
(Figure 7) for a write sequence.
During the read sequence, the P sends a prompt
pulse causing the device to output the data word LSB
first. Similar to the write transaction, the read transac-
tion must be preceded by an address sequence. If
more than 8 prompts (MAX7428), 16 prompts
(MAX7430), or 24 prompts (MAX7432A) are available,
the device outputs the same data starting with the LSB
again. The following is the command sequence and
timing diagram (Figure 8) for a read sequence.
