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

Chaining uPSD34xx devices
It is possible to chain a uPSD34xx device with other uPSD34xx devices on a circuit board,
and also chain with IEEE 1149.1 compliant devices from other manufacturers.

device, and so on. Only one device is performing JTAG operations at any given time while
the other two devices are in BYPASS mode. Configuration for JTAG chaining can be made in
PSDsoft Express by choosing “More than one device” when prompted about chaining
devices. Notice in
but also be aware that the two die within each uPSD34xx device are chained internally. This
internal chaining of die is transparent to the user and is taken care of by PSDsoft Express
and 3rd party JTAG tool software.
The example in
devices. The signals TSTAT and TERR are configured as open-drain type signals from
PSDsoft Express. This facilitates a wired-OR connection of TSTAT signals from multiple
uPSD34xx devices and also a wired-OR connection of TERR signals from those same
multiple devices. PSDsoft Express puts TSTAT and TERR signals into open-drain mode by
default, requiring external pull-up resistors. Click on 'Properties' in the JTAG-ISP window of
PSDsoft Express to change to standard CMOS push-pull outputs if desired, but wired-OR
logic is not possible in CMOS output mode.
