) • Industrial operating temperature range: –40°C to +85°C • FCT (2xxxT) has a 25 Ω series resistor.
• Packages available: – 24-pin 300 mil wide plastic DIP (P24) – 24-pin 150 mil wide plastic QSOP (Q24) – 24-pin 150 mil wide plastic TQSOP (R24) – 24-pin 300 mil wide plastic SOIC (S24) Product Description: Pericom Semiconductor’s PI29FCT series of logic circuits are pro-duced in the Company’s advanced 0.
8 micron CMOS technology, achieving industry leading speed grades.
The PI29FCT520T/2520T and PI29FCT521T are multilevel pipeline registers containing four 8-bit positive triggered registers which can be configured as a dual 2-level or a single 4-level pipeline.
These products are designed for use as temporary storage or for storage delays in pipelined systems.
The PI29FCT521T differs from the PI29FCT520T/2520T only in the way data is loaded into and between registers in the dual 2-level operation.
When data is entered into the first level (I = 2 or I = 1) of the PI29FCT520T/2520T, the existing data in the first level is moved to the second level.
In the PI29FCT521T, these instructions simply overwrite the data in the first level.
Transfer of data to the second level is achieved using the 4-level shift instruction (I = 0) causing the first level to change.
