NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100%
matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations).
Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC
J STD-020.
2. Not recommended for new designs.
Pin Descriptions
Host Interface Pins
SERIAL OUTPUT (SO)
SO is a push/pull serial data output pin. During a read cycle,
data is shifted out on this pin. Data is clocked out by the
falling edge of the serial clock.
SERIAL INPUT
SI is the serial data input pin. All opcodes, byte addresses
and data to be written to the pots and pot registers are input
on this pin. Data is latched by the rising edge of the serial
clock.
SERIAL CLOCK (SCK)
The SCK input is used to clock data into and out of the
X9401.
CHIP SELECT (CS)
When CS is HIGH, the X9401 is deselected and the SO pin
is at high impedance, and (unless an internal write cycle is
underway) the device will be in the standby state. CS LOW
enables the X9401, placing it in the active power mode. It
should be noted that after a power-up, a HIGH to LOW
transition on CS is required prior to the start of any
operation.
