IDT72V3683L15PF集成電路（IC）的FIFO存儲器規(guī)格書PDF中文資料

DESCRIPTION

The IDT72V3683/72V3693/72V36103 are designed to run off a 3.3V supply for exceptionally low power consumption. These devices are monolithic, high-speed, low-power, CMOS unidirectional Synchronous (clocked) FIFO memory which supports clock frequencies up to 100 MHz and has read access times as fast as 6.5 ns. The 16,384/32,768/65,536 x 36 dual-port SRAM FIFO buffers data from Port A to Port B. FIFO data on Port B can output in 36-bit, 18-bit, or 9-bit formats with a choice of Big- or Little-Endian configurations.

FEATURES

? Memory storage capacity:

IDT72V3683 – 16,384 x 36

IDT72V3693 – 32,768 x 36

IDT72V36103 – 65,536 x 36

? Clock frequencies up to 100 MHz (6.5 ns access time)

? Clocked FIFO buffering data from Port A to Port B

? IDT Standard timing (using EF and FF) or First Word Fall Through Timing (using OR and IR 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

? 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)

? Easily expandable in width and depth

? Auto power down minimizes power dissipation

? Available in a space-saving 128-pin Thin Quad Flatpack (TQFP)

? Pin compatible with the lower density parts, IDT72V3623/ 72V3633/72V3643/72V3653/72V3663/72V3673

? Industrial temperature range (–40°C to +85°C) is available
