10-Port SPI-Interfaced I/O Expander with

Overvoltage and Hot-Insertion Protection

Alternatively, MAX7317s can be daisy-chained by con-

necting the DOUT of one device to the DIN of the next,

and driving SCLK and CS lines in parallel (Figure 3).

This connection allows the MAX7317s to be read. Data

at DIN propagates through the internal shift registers

and appears at DOUT 15.5 clock cycles later, clocked

out on the falling edge of SCLK. When sending com-

mands to daisy-chained MAX7317s, all devices are

accessed at the same time. An access requires (16 x n)

clock cycles, where n is the number of MAX7317s con-

nected together. The serial interface speed (maximum

SCLK) is limited to 10MHz when multiple devices are

daisy-chained due to the DOUT propagation delay and

DIN setup time.

If fewer or greater than 16 bits are clocked into the

MAX7317 between taking CS low and taking CS high

again, the MAX7317 stores the last 16 bits received,

including the previous transmission(s). The general

case is when n bits (where n > 16) are transmitted to

the MAX7317. The last bits comprising bits {n-15} to

{n}, are retained, and are parallel loaded into the 16-bit

latch as bits D15 to D0, respectively (Figure 6).

Reading Device Registers

Any register data within the MAX7317 can be read by

sending a logic high to bit D15. The sequence is:

1) Take SCLK low.

2) Take CS low. This enables the internal 16-bit shift

The MAX7317 is written to using the following

sequence (Figure 5):

3) Clock 16 bits of data into DIN, D15 first to D0 last.

D15 is high, indicating a read command and bits

D14 through D8 contain the address of the register

to read. Bits D7 to D0 contain dummy data, which is

discarded.

1) Take SCLK low.

2) Take CS low. This enables the internal 16-bit shift

3) Clock 16 bits of data into DIN, D15 first to D0 last,

observing the setup and hold times. Bit D15 is low,

indicating a write command.

4) Take CS high (either while SCLK is still high after

clocking in the last data bit, or after taking SCLK

low). Positions D7 through D0 in the shift register are

now loaded with the register data addressed by bits

D15 through D8.

4) Take CS high (either while SCLK is still high after

clocking in the last data bit, or after taking SCLK low).

5) Take SCLK low (if not already low).

6) Issue another read or write command, and examine

the bit stream at DOUT; the second 8 bits are the

contents of the register addressed by bits D14

through D8 in step 3.
