SCANPSC100F
Embedded Boundary Scan Controller
(IEEE 1149.1 Support)
General Description
The SCANPSC100F is designed to interface a generic par-
allel processor bus to a serial scan test bus. It is useful in
improving scan throughput when applying serial vectors to
system test circuitry and reduces the software overhead that
is associated with applying serial patterns with a parallel
processor. The ’PSC100F operates by serializing data from
the parallel bus for shifting through the chain of 1149.1
compliant components (i.e., scan chain). Scan data return-
ing from the scan chain is placed on the parallel port to be
read by the host processor. Up to two scan chains can be
directly controlled with the ’PSC100F via two independent
TMS pins. Scan control is supplied with user specific pat-
terns which makes the ’PSC100F protocol-independent.
Overflow and underflow conditions are prevented by stop-
ping the test clock. A 32-bit counter is used to program the
number of TCK cycles required to complete a scan operation
within the boundary scan chain or to complete a ’PSC100F
Built-In Self Test (BIST) operation. SCANPSC100F device
drivers and 1149.1 embedded test application code are
available with National’s SCANEase software tools.
