RENESAS 71V25761S183PFGI

The IDT71V25761 are high-speed SRAMs organized as 128K x 36. The IDT71V25761 SRAMs contain write, data, address and control registers. Internal logic allows the SRAM to generate a self-timed write based upon a decision which can be left until the end of the write cycle. The burst mode feature offers the highest level of performance to the system designer, as the IDT71V25761 can provide four cycles of data for a single address presented to the SRAM. An internal burst address counter accepts the first cycle address from the processor, initiating the access sequence. The first cycle of output data will be pipelined for one cycle before it is available on the next rising clock edge. If burst mode operation is selected (ADV=LOW), the subsequent three cycles of output data will be available to the user on the next three rising clock edges. The order of these three addresses are defined by the internal burst counter and the LBO input pin. The IDT71V25761 SRAMs utilizes a high-performance CMOS process and are packaged in a JEDEC standard 14mm x 20mm 100-pin thin plastic quad flatpack (TQFP).
