System designer has full flexibility of implementing deeper and wider queues using the depth and width expansion features. Full and Empty indicators allow easy handshaking between transmitters and receivers. Independent Write and Read controls provide rate-matching capability. System designer can re-read data from the starting ________ __________ position by using Retransmit (RET). Retransmit allows reset of the read pointer to its initial position. Half Full flag (HALF) is available in the single device mode and width expansion mode, but not in depth expansion mode. These FlexQTM Async devices have low power consumption, hence minimizing system power requirements. In addition, industry standard 28 - pin PDIP, 28 - pin PTDIP, 28 - pin SOIC, 32 - pin TQFP and 32 - pin PLCC are offered to save system board space. These queues are ideal for applications such as data communication, telecommunication, graphics, multiprocessing, test equipment, medical systems, network switching, etc. 5FA09C (c) 2003 High Bandwidth Access, Inc.

Bidirectional Mode Data Flow-Through Mode: There are two types of flow-through modes, read flow-through and write flow-through. In the read flow-through mode, the device allows a single word to be read after one word of data has been written into an empty FIFO. The ____ ___ data is enabled on the bus_____________ after the rising edge of W, and remains on the bus until R goes from Low to High. Then the bus goes write flowinto a three-state mode. EMPTY will have a pulse showing temporary deassertion and then would be asserted. In the ___ causes through mode, the device allows a single word to be written after one word of data has been read from a full FIFO. R __________ ____ FULL to be deasserted but a Low W causes it to be asserted again for the new data word. The new word goes into the FIFO on ____ ____ __________ the rising edge of W. W must be toggled when FULL is not asserted to write new data into the FIFO and to increment the write pointer. 5FA09C (c) 2003 High Bandwidth Access, Inc. All rights reserved.
