DESCRIPTION
The Xicor X9511 is a push button controlled, potentiom-
eter and is ideal for push button controlled resistance
trimming.
The X9511 is a resistor array composed of 31 resistive
elements. Between each element and at either end are
tap points accessible to the wiper element. The position
of the wiper element is controlled by the PU and PD
inputs. The position of the wiper can be automatically
stored in E2 memory and then be recalled upon a subse-
quent power-on operation.
The resolution of the X9511 is equal to the maximum
resistance value divided by 31. As an example, for the
X9511W (10K) each tap point represents 323.
All Xicor nonvolatile products are designed and tested for
applications requiring extended endurance and data
retention.

PIN DESCRIPTIONS
VH and VL
The high (VH) and low (VL) terminals of the X9511 are
equivalent to the fixed terminals of a mechanical potenti-
ometer. The minimum voltage is –5V and the maximum
is +5V. It should be noted that the terminology of VL and
VH references the relative position of the terminal in rela-
tion to wiper movement direction selected by the PU and
PD inputs and not the voltage potential on the terminal.
PU
The debounced PU input is for incrementing the wiper
position. An on-chip pull-up holds the PU input HIGH. A
switch closure to ground or a LOW logic level will, after a
debounce time, move the wiper to the next adjacent
higher tap position.
PD
The debounced PD input is for decrementing the wiper
position. An on-chip pull-up holds the PD input HIGH. A
switch closure to ground or a LOW logic level will, after a
debounce time, move the wiper to the next adjacent
lower tap position.
ASE
The debounced ASE (AUTOSTORE enable) pin can be
in one of two states:
VIL – Autostore is enabled. When VCC powers-down an
automatic store cycle takes place.
VIH – AUTOSTORE is disabled. A LOW to HIGH will ini-
tiate a manual store operation. This is for a user who
wishes to connect a push button switch to this pin. For
every valid push, the X9511 will store the current wiper
position to the E2PROM.
