SCAN Bridge Hierarchical and Multidrop Addressable
JTAG Port (IEEE1149.1 System Test Support)
General Description
The SCANPSC110F Bridge extends the IEEE Std. 1149.1
test bus into a multidrop test bus environment. The advan-
tage of a hierarchical approach over a single serial scan
chain is improved test throughput and the ability to remove
a board from the system and retain test access to the
remaining modules. Each SCANPSC110F Bridge supports
up to 3 local scan rings which can be accessed individually
or combined serially. Addressing is accomplished by load-
ing the instruction register with a value matching that of the
Slot inputs. Backplane and inter-board testing can easily
be accomplished by parking the local TAP Controllers in
one of the stable TAP Controller states via a Park instruc-
tion. The 32-bit TCK counter enables built in self test oper-
ations to be performed on one port while other scan chains
are simultaneously tested.
Features
I
True IEEE1149.1 hierarchical and multidrop addressable
capability
I
The 6 slot inputs support up to 59 unique addresses, a
Broadcast Address, and 4 Multi-cast Group Addresses
I
3 IEEE 1149.1-compatible configurable local scan ports
I
Mode Register allows local TAPs to be bypassed,
selected for insertion into the scan chain individually, or
serially in groups of two or three
I
32-bit TCK counter
I
16-bit LFSR Signature Compactor
I
L4
I
local TAPs can be 3-stated via the OE input to allow an
alternate test master to take control of the local TAPs
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
