Applications Information
Maxim’s Single Pin Bus (MSPB)
Serial Interface
The MSPB interface uses three pulses of different
widths to represent commands and data bits. Figure 4
shows the set of pulses that the single pin interface
uses to communicate with the device. A combination of
the one pulse (t1), zero pulse (t0), transaction pulse (tT),
and prompt pulse (tP), writes to, reads back from, and
sends broadcast data to the devices on the bus.
Note: The zero pulse and prompt pulse are the same.
Initialization pulses are significantly longer and are
used only on power-up or software reset.
Initializing the
MAX7428/MAX7430/MAX7432A
Initialization is performed only after power-up or software
reset. It assigns a unique address to each device on the
bus. The time constant of the capacitor connected to
REXT in parallel with the 300k
Ω resistor determines the
order in which the devices are initialized (address
assigned). The device with the largest time constant is
initialized first and so on, in descending order. Table 7
shows the “Initialize Wait” and “Initialize Time” pulse
widths needed for a specific capacitor value and toler-
ance. Program each device on the bus with this com-
mand sequence starting with the device with the biggest
capacitor. To reinitialize a device, cycle the power or use
a software reset. The following is the command
sequence and timing diagram (Figure 5) for initialization
as shown below. Chip ID is entered LSB first.
Note: If there is only one device on the bus, no initial-
ization is needed. Communicate to the device using the
broadcast command described on page 13.
