General Description
The SCANSTA101 is designed to function as a test master for a IEEE 1149.1 test system. The minimal requirements to create
a tester are a microcomputer (uP, RAM/ROM, clock, etc.), SCANEASE r2.0 software, and a STA101.
The SCANSTA101 is an enhanced version of, and replacement for, the SCANPSC100. The additional features of the STA101 further
allow it to offload some of the processor overhead while remaining flexible. The device architecture supports IEEE 1149.1,
BIST, and IEEE 1532. The flexibility will allow it to adapt to any changes that may occur in 1532 and support yet unknown
variants.
The SCANSTA101 is useful in improving vector 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 SCANSTA101 features
a generic Parallel Processor Interface (PPI) which operates by serializing data from the parallel bus for shifting through
the chain of 1149.1 compliant components (i.e., scan chain). Writes can be controlled either by wait states or the
^DTACK line. Handshaking is accomplished with either polling or interrupts.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
