IDT IDT71V2577S IDT71V2579S Synchronous SRAM Datasheet

About this manual

The IDT71V2577S and IDT71V2579S are high-speed synchronous SRAMs available in 128K x 36 and 256K x 18 configurations. They support fast access times up to 117MHz and include burst mode for improved performance. The devices feature flow-through outputs, no output registers, and optional JTAG interface. They are packaged in 100-pin TQFP, 119-BGA, or 165-fBGA formats.

Power is supplied via a 3.3V core and 2.5V I/O, with sleep mode controlled by the ZZ pin. The datasheet details pin functions, timing, and absolute maximum ratings for commercial and industrial temperature ranges.
