Product Description
HBA’s FlexQ™ III Plus offers industry leading FIFO queuing bandwidth (up to 12.0 Gbps) with a wide range of memory
configurations (from 512 x 80 to 65,536 x 80). System designer has full flexibility of implementing deeper and wider queues
using FWFT mode and width expansion features. Full, Empty, and Half-Full indicators allow easy handshaking between
transmitters and receivers. User programmable Almost Full and Almost Empty (Parallel/Serial) indicators allow implementation
of virtual queue depths.
5V tolerant on all input and output pins allow easy interfacing with devices operating at higher voltage levels. Asynchronous
Output Enable pin configures the tri-state data output drivers. In addition, synchronous read chip select is also available to
control the state of data output drivers. Independent Write and Read controls provide rate-matching capability.
Master Reset clears all previous programmed configurations by providing a low pulse on MRST pin. In addition, Write and
Read pointers to the queue are initialized to zero. Partial Reset will not alter previously programmed configurations but will
initialize Write and Read pointers to zero.
In FWFT mode, first data written into the queue appears on output data bus after the specified latency period at the low to high
transition of RCLK. Subsequent reads from the queue will require asserting REN . This feature is useful when implementing
depth expansion functions. In this mode, DRDY and QRDY are used instead of FULL and EMPTY respectively.
