Figure 92.
Recommended 6-pin JTAG connections
1.
For 5 V UPSD34xx devices, pull-up resistors and VCC pin on the JTAG connector should be connected to
5 V system VDD.
2.
For 3.3 V UPSD34xx devices, pull-up resistors and VCC pin on the JTAG connector should be connected to
3.3 V system VCC.
3.
This signal is driven by an Open-Drain output in the JTAG equipment, allowing more than one source to
activate RESET_IN.
28.6.6
Recommended JTAG connector
There is no industry standard JTAG connector. STMicroelectronics recommends a specific
JTAG connector and pinout for uPSD3xxx so programming and debug equipment will easily
connect to the circuit board. The user does not have to use this connector if there is a
different connection scheme.
The recommended connector scheme can accept a standard 14-pin ribbon cable connector
(2 rows of 7 pins on 0.1” centers, 0.025” square posts, standard keying) as shown in
Figure 93. See the STMicroelectronics “FlashLINK, FL-101 User Manual” for more
information.
