SCANPSC100F
Embedded Boundary Scan Controller
(IEEE 1149.1 Support)
General Description
The SCANPSC100F is designed to interface a generic paral-
lel processor bus to a serial scan test bus. It is useful in im-
proving scan throughput when applying serial vectors to sys-
tem test circuitry and reduces the software overhead that is
associated with applying serial patterns with a parallel pro-
cessor. 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 returning 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 con-
trolled with the ’PSC100F via two independent TMS pins.
Scan control is supplied with user specific patterns which
makes the ’PSC100F protocol-independent. Overflow and
underflow conditions are prevented by stopping the test
clock.A32-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.
