PIN ASSIGNMENT
Pin
Name
Function
1
RH2
Connection to end of resistor array for (the 256 Tap) DCP 2.
2
Rw2
Connection to terminal equivalent to the “Wiper” of a mechanical potentiometer for DCP 2.
3
RL2
Connection to other end of resistor array for (the 256 Tap) DCP 2.
4V3
V3 Voltage Monitor Input. V3 is the input to a non-inverting voltage comparator circuit. When the V3
input is higher than the
VTRIP3 threshold voltage, V3RO makes a transition to a HIGH level. Connect
V3 to VSS when not used.
5V3RO
V3 RESET Output. This open drain output makes a transition to a HIGH level when V3 is greater than
VTRIP3 and goes LOW when V3 is less than VTRIP3. There is no delay circuitry on this pin. The V3RO
pin requires the use of an external “pull-up” resistor.
6MR
Manual Reset. MR is a TTL level compatible input. Pulling the MR pin active (HIGH) initiates a reset
cycle to the V1RO pin (V1/Vcc RESET Output pin). V1RO will remain HIGH for time tpurst after MR has
returned to it’s normally LOW state. The reset time can be selected using bits POR1 and POR0 in the
CONSTAT Register. The MR pin requires the use of an external “pull-down” resistor.
7WP
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 DCP Write Lock feature is active (i.e. the DCP Write Lock bit is
“1”), then no “write” (volatile or nonvolatile) operations can be performedon the wiper position of any of
the integrated Digitally Controlled Potentiometers (DCPs). The WP pin uses an internal “pull-down” re-
sistor, thus if left floating the write protection feature is disabled.
8SCL
Serial Clock. This is a TTL level compatible input pin used to control the serial bus timing for data input
and output.
9SDA
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 re-
sistor.
10
Vss
Ground.
11
RL1
Connection to other end of resistor for (the 100 Tap) DCP 1.
12
Rw1
Connection to terminal equivalent to the “Wiper” of a mechanical potentiometer for DCP 1.
13
RH1
Connection to end of resistor array for (the 100 Tap) DCP 1.
17
V2
V2 Voltage Monitor Input. V2 is the input to a non-inverting voltage comparator circuit. When the V2
input is greater than the
VTRIP2 threshold voltage, V2RO makes a transition to a HIGH level. Connect
V2 to VSS when not used.
18
V2RO
V2 RESET Output. This open drain output makes a transition to a HIGH level when V2 is greater than
VTRIP2, and goes LOW when V2 is less than VTRIP2. There is no power-up reset delay circuitry on this
pin. The V2RO pin requires the use of an external “pull-up” resistor.
19
V1RO
V1 / Vcc RESET Output. This is an active HIGH, open drain output which becomes active whenever
V1 / Vcc falls below
VTRIP1. V1RO becomes active on power-up and remains active for a time tpurst
after the power supply stabilizes (tpurst can be changed by varying the POR0 and POR1 bits of the
internal control register). The V1RO pin requires the use of an external “pull-up” resistor. The V1RO
pin can be forced active (HIGH) using the manual reset (MR) input pin.
20
V1 / Vcc
Supply Voltage.
14, 15,
