FCT162701T Application Example i486 FCT162701T CacheRAM PAL CLK,WCE, RCE, RST CLK W/R LE,OEBA, OEAB DRAM Coprocessor A B FUNCTIONAL DESCRIPTION: This device is useful as a read/write buffer for modular high end designs. It provides multi-level buffering in the write path and single deep buffering in the read path, and is suited to write back cache implementation. The read path provides a transparent latch. The four deep FIFO uses one clock with two clock enable pins, WCE and RCE to clock data in and out. The FIFO has an external full flag which goes LOW when the FIFO is full. Internal read and write pointers keep track of the words stored in the FIFO. A write attempt to a full FIFO is ignored. An attempt to read from an empty FIFO will have no effect and the last read data remains at the output of the FIFO. The FIFO may be reset by the synchronous RESET input. This resets the read and write pointers to the original "empty" condition and also sets all B outputs = 1. Simultaneous read and write attempts (clock data into FIFO as well as clock data out of FIFO) are possible except on FIFO empty and full boundaries. When the FIFO is empty, and a simultaneous read and write is attempted, the read is ignored while the write is executed. If the same is attempted when the FIFO is full, the write is ignored while the read is executed. Normal operation of the four deep FIFO in the write path is independent of the read path operation. Power, ground and data pin positions on the FCT162701T match those on the FCT16501T/162501T, allowing an easy upgrade. |
