*Add "T1" suffix for tape and reel.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are 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.

Function
Connection to end of resistor array for (the 256 Tap) DCP 2.
Connection to terminal equivalent to the “Wiper” of a mechanical potentiometer for DCP 2.
Connection to other end of resistor array for (the 256 Tap) DCP 2.
Physical Device Address input. A match in the slave address serial data stream, and the Physical De-
vice Address input pin must be in order to initiate communication with the X9525. A maximum of two
(2) devices may occupy the same 2-wire serial bus.
Write Protect Control Pin. WP pin is a TTL level compatible input. When held HIGH, Write Protection
is enabled. In the enabled state, this pin prevents all nonvolatile “write” operations. Also, when the Write
Protection is enabled, and the device Block Lock feature is active (i.e. the Block Lock bits are NOT
[0,0]), then no “write” (volatile or nonvolatile) operations can be performed in the device (including the
wiper position of any of the integrated Digitally Controlled Potentiometers (DCPs). The WP pin uses an
internal “pull-up” resistor, thus if left floating the write protection feature is enabled.
Serial Clock. This is a TTL level compatible input pin used to control the serial bus timing for data input
and output.
Serial Data. SDA is a bidirectional TTL level compatible pin used to transfer data into and out of the
device. The SDA pin input buffer is always active (not gated). This pin requires an external pull up
resistor.
Ground.
Connection to other end of resistor for (the 100 Tap) DCP 1.
Connection to terminal equivalent to the “Wiper” of a mechanical potentiometer for DCP 1.
Connection to end of resistor array for (the 100 Tap) DCP 1.
