CAT5401
Document No. 2010, Rev. F
DEVICE OPERATION
The CAT5401 is four resistor arrays integrated with SPI
serial interface logic, four 6-bit wiper control registers
and sixteen 6-bit, non-volatile memory data registers.
Each resistor array contains 63 separate resistive
elements connected in series. The physical ends of
each array are equivalent to the fixed terminals of a
mechanical potentiometer (R
H
and R
L
). R
H
and
R
L
are
symmetrical and may be interchanged. The tap positions
between and at the ends of the series resistors are
connected to the output wiper terminals (R
W
) by a
CMOS transistor switch. Only one tap point for each
potentiometer is connected to its wiper terminal at a time
and is determined by the value of the wiper control
register. Data can be read or written to the wiper control
registers or the non-volatile memory data registers via
the SPI bus. Additional instructions allows data to be
transferred between the wiper control registers and
each respective potentiometer's non-volatile data
registers. Also, the device can be instructed to operate
in an "increment/decrement" mode.
SERIAL BUS PROTOCOL
The CAT5041 supports the SPI bus data transmission
protocol. The synchronous Serial Peripheral Interface
(SPI) helps the CAT5401 to interface directly with many
of today's popular microcontrollers. The CAT5041
contains an 8-bit instruction register .The instruction set
and the operation codes are detailed in the instruction
set table
3.
After the device is selected with
CS
going low the first
byte will be received. The part is accessed via the SI pin,
with data being clocked in on the rising edge of SCK. The
first byte contains one of the six op-codes that define the
operation to be performed.
