Features True IEEE 1149.1 hierarchical and multidrop addressable capability The 7 slot inputs support up to 121 unique addresses, an Interrogation Address, Broadcast Address, and 4 Multi-cast Group Addresses (address 000000 is reserved) 3 IEEE 1149.1-compatible configurable local scan ports Mode Register0 allows local TAPs to be bypassed, selected for insertion into the scan chain individually, or serially in groups of two or three Transparent Mode can be enabled with a single instruction to conveniently buffer the backplane IEEE 1149.1 pins to those on a single local scan port LSP ACTIVE outputs provide local port enable signals for analog busses supporting IEEE 1149.4. General purpose local port Pass-through bits are useful for delivering write pulses for FPGA programming or monitoring device status. Known Power-up state ^TRST on all local scan ports 32-bit TCK counter 16-bit LFSR Signature Compactor Local TAPs can become TRI-STATE via the ^OE input to allow an alternate test master to take control of the local TAPs (LSP0-2 have a TRI-STATE notification output) 3.0-3.6V VCC Supply Operation Power-off high impedance inputs and outputs Supports live insertion/withdrawal Description The SCANSTA111 extends the IEEE Std. 1149.1 test bus into a multidrop test bus environment. The advantage of a multidrop 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 SCANSTA111 supports up to 3 local IEEE 1149.1 scan rings which can be accessed individually or combined serially. Addressing is accomplished by loading 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 instruction. The 32-bit TCK counter enables built in self test operations to be performed on one port while other scan chains are simultaneously tested.

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.
