DETAILED PIN DESCRIPTION

SOIC
SYMBOL
DESCRIPTION
PIN 1
VDDD
Digital Supply Voltage 1.8V-5.5V. Defines the top rails for the digital
inputs and outputs.
PIN 2
CE
Chip Enable Must be asserted high for communication to take place for
either the SPI or 3-wire interface.
PIN 3
SCLK
Serial Clock Input Used to synchronize data movement on the serial
interface for either the SPI or 3-wire interface.
PIN 4
GND
Ground pin.
PIN 5
SDO
Serial Data Output When SPI communication is selected, the SDO pin is
the serial data output for the SPI bus. When 3-wire communication is
selected, this pin must be tied to the SDI pin (the SDI and SDO pins function
as a single I/O pin when tied together.)
PIN 6
SDI
Serial Data Input When SPI communication is selected, the SDI pin is the
serial data input for the SPI bus. When 3-wire communication is selected,
this pin must be tied to the SDO pin (the SDI and SDO pins function as a
single I/O pin when tied together.)
PIN 7
SERMODE
Serial Interface Mode Input This pin selects which interface standard will
be used: SPI when connected to VCC ; standard 3-wire when connected to
GND.
PIN 8
VDDA
Analog Supply Voltage 2.65V – 5.5V input power pin.
