while still being able to immediately address and
update individual outputs in the matrix.
Individual Output Address Mode (MODE = 0)
Drive MODE to logic low to select Mode 0. Individual
outputs are programmed through the serial interface
with a single 16-bit control word. The control word con-
sists of a don
’
t care MSB, the chip address bits, output
address bits, an output enable/disable bit, an output
gain-set bit, and input address bits (Table 2 through
Table 6, and Figure 2).
In Mode 0, data at DIN passes directly to DOUT
through the data routing gate (Figure 3). In this configu-
ration, the 16-bit control word is simultaneously sent to
all chips in an array of up to 16 addresses.
Complete Matrix Mode (MODE = 1)
Drive MODE to logic high to select Mode 1. A single
112-bit control word, consisting of sixteen 7-bit control
words, programs all outputs. The 112-bit control word
’
s
first 7-bit control word (MSBs) programs output 15, and
the last 7-bit control word (LSBs) programs output 0
(Table 7 and Figures 4 and 5). Data clocked into the
112-bit Complete Matrix Mode register is latched on the
falling edge of
UPDATE
, and the outputs are immedi-
ately updated.
Initialization S tring
Complete Matrix Mode (Mode = 1) is convenient for
programming the matrix at power-up. In a large matrix
consisting of many MAX4357s, all the devices can be
programmed by sending a single bit stream equal to n
x 112 bits where n is the number of MAX4357 devices
on the bus. The first 112-bit data word programs the
last MAX4357 in line (see
Matrix Programming
section).
RESET
The MAX4357 features an asynchronous bidirectional
RESET
with an internal 20k
pullup resistor to V
DD
.
