CY29FCT818T  
SCCS012 - May 1994 - Revised February 2000  
Diagnostic Scan Register  
ter is designed for applications, such as diagnostics in sequen-  
tial circuits, where it is desirable to load known data at a spe-  
cific location in the circuit and to read the data at that location.  
Features  
• Function,pinoutanddrivecompatiblewithFCT,FLogic  
and AM29818  
• FCT-C speed at 6.0 ns max. (Com’l),  
FCT-A speed at 12.0 ns max. (Mil)  
• Reduced VOH (typically = 3.3V) versions of equivalent  
FCT functions  
• Edge-rate control circuitry for significantly improved  
noise characteristics  
The shadow registers can load data from the output of the  
FCT818T, and can be used as a right-shift register with  
bit-serial input SDI and output SDO, using DCLK. The data  
register input is multiplexed to enable loading from the shadow  
register or from the data input pins using PCLK. Note that data  
can be loaded simultaneously from the shadow register to the  
pipeline register, and from the pipeline register to the shadow  
register provided set-up and hold time requirements are  
satisfied with respect to the two independent clock inputs.  
• Power-off disable feature  
• Matched rise and fall times  
• Fully compatible with TTL input and output logic levels  
In a typical application, the general-purpose register in the  
FCT818T replaces an 8-bit data register in the normal data  
path of a system. The shadow register is placed in an auxiliary  
bit-serial loop which is used for diagnostics. During diagnostic  
operation, data is shifted serially into the shadow register, then  
transferred to the general purpose register to load a known  
value into the data path. To read the contents at that point in  
the data path, the data is transferred from the data register into  
the shadow register, then shifted serially in the auxiliary  
diagnostic loop to make it accessible to the diagnostics  
controller. This data is then compared with the expected value  
to diagnose faulty operation of the sequential circuit.  
• Sink current  
64 mA (Com’l),  
20 mA (Mil)  
Source current 32 mA (Com’l),  
3 mA (Mil)  
• 8-Bit pipeline and shadow register  
• ESD > 2000V  
Functional Description  
The FCT818T contains a high-speed 8-bit general-purpose  
data pipeline register and a high-speed 8-bit shadow register.  
The general-purpose register can be used in an 8-bit wide  
data path for a normal system application. The shadow regis-  
The outputs are designed with a power-off disable feature to  
allow for live insertion of boards.
