DESCRIPTION
The IDT723654/723664/723674 is a monolithic, high-speed, low-power, CMOS bidirectional synchronous (clocked) FIFO memory which supports clock frequencies up to 83 MHz and has read access times as fast as 8ns. Two independent 2,048/4,096/8,192 x 36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions. FIFO data on Port B can be input and output in 36-bit, 18-bit, or 9-bit formats with a choice of Big- or Little-Endian configurations.
FEATURES
? Memory storage capacity:
IDT723654 – 2,048 x 36 x 2
IDT723664 – 4,096 x 36 x 2
IDT723674 – 8,192 x 36 x 2
? Clock frequencies up to 83 MHz (8ns access time)
? Two independent clocked FIFOs buffering data in opposite directions
? Select IDT Standard timing (using EFA, EFB, FFA, and FFB flags functions) or First Word Fall Through Timing (using ORA, ORB, IRA, and IRB flag functions)
? Programmable Almost-Empty and Almost-Full flags; each has five default offsets (8, 16, 64, 256 and 1,024 )
? Serial or parallel programming of partial flags
? Port B bus sizing of 36 bits (long word), 18 bits (word) and 9 bits (byte)
? Big- or Little-Endian format for word and byte bus sizes
? Retransmit Capability
? Master Reset clears data and configures FIFO, Partial Reset clears data but retains configuration settings
? Mailbox bypass registers for each FIFO
? Free-running CLKA and CLKB may be asynchronous or coincident (simultaneous reading and writing of data on a single clock edge is permitted)
? Auto power down minimizes power dissipation
? Available in space saving 128-pin Thin Quad Flatpack (TQFP)
? Pin compatible to the lower density parts, IDT723624/723634/723644
? Industrial temperature range (–40°C to +85°C) is available
