In addition, Endian Select is available for implementing byte re-ordering on data outputs.
Eight different default offset values are available for Almost Full ( PRAF ) and Almost Empty ( PRAE ) flags. Parallel and Serial
programming of these offset values provide total flexibility other than the pre-defined default values. Both 8-bit and 9-bit parallel
programming modes for offset values can be selected for convenience.
PRAF , PRAE , and HALF are available in either FWFT or Standard mode. PRAF and PRAE can operate in either synchronous or
asynchronous mode.
At any time, data previously read from the queue can be retransmitted by asserting RET pin at the low to high transition of RCLK for a
retransmit operation. Retransmit initializes the Read pointer to zero. Hence, all re-reads will always start from the physical 0th (Read
pointer = zero) location of the queue. Both zero and normal latency timing modes are available for retransmit operation.
These FlexQ™ III devices have low power consumption, hence minimizing system power requirements. In addition, industry standard 128
- pin Plastic TQFP is offered to save system board space.
These queues are ideal for applications such as data communication, telecommunication, graphics, multiprocessing, test equipment, network
switching, etc.
