4 EVM Connectors
This section describes the connectors, jumpers, and test points on the EVM as well as how to connect, set up,
and properly use the EVM.
4.1 EVM Jumpers
Tables 4-1 , 4-2 , 4-3 , and 4-4 list the default jumper connections and functional descriptions for each device
configuration. Each pinout configuration detailed in this section applies to all TPS3435-Q1, TPS3436-Q1,
TPS35-Q1, and TPS36-Q1 device families. Please note that for pinouts A, B and C, Pin 7 refers to RESET
for the TPS35-Q1 and TPS36-Q1 devices and WDO for the TPS3435-Q1 and TPS3436-Q1 devices.

DESCRIPTION
Pin 1 / MR J1 Closed (pin 7, pin 8) Jumper J1 configures the MR pin. Connect a shunt jumper to pins 7-8 of
jumper J1 to enable the device (logic high) or to pins 5-6 to disable the
device (logic low).
Pin 2 / CWD J2 Closed (pin 1, pin 2) Jumper J2 configures the CWD pin. Connect a shunt jumper to pins 7-8
to connect to V
DD
, pins 3-4 to connect to C6, and pins 1-2 to connect to
C7. Refer to 5.8 CWD and the data sheet for more details on watchdog
timeout periods. Do not connect to pins 5-6 in this configuration.
Pin 3 / CRST J3 Closed (pin 1, pin 2) Jumper J3 configures the CRST pin. Connect a shunt jumper to pins 7-8
to connect to V
DD
, pins 3-4 to connect to C6, and pins 1-2 to connect to
C7. Refer to 5.7 CRST and the data sheet for more details on watchdog
timeout periods. Do not connect to pins 5-6 in this configuration.
Pin 5 / SET0 J4 Closed (pin 2, pin 3) Jumper J4 configures the SET0 pin. Connect a shunt jumper to pins 1-2
of jumper J3 to input a logic high or to pins 2-3 to input a logic low.
Please refer to the data sheet for SETx functionality.
Pin 6 / WDI J5 Closed (pin 3, pin 4) Jumper J5 configures the WDI pin. Connect a shunt jumper to pins 7-8 to
input a WDI signal through TP3. A rising edge must be occur at this pin
during the open window in order for RESET/WDO to not assert.
Pin 7 / RESET /
WDO J6 Closed (pin 1, pin 2) Jumper J6 is used if there is an open-drain variant being evaluated.
Connect a shunt jumper to pins 1-2 to activate pull-up resistor R2 and
pull the RESET output high. Disconnect pins 1-2 if using a push-pull
variant.
