IDT71V433 x x x x x x x Description The IDT71V433 is a 3.3V high-speed 1,048,576-bit SRAM organized as 32K x 32 with full support of various processor interfaces including the Pentium™ and PowerPC™. The flow-through burst architecture provides cost-effective 2-1-1-1 performance for processors up to 50 MHz. The IDT71V433 SRAM contains write, data-input, address and control registers. There are no registers in the data output path (flowthrough architecture). Internal logic allows the SRAM to generate a self-timed write based upon a decision which can be left until the extreme end of the write cycle. The burst mode feature offers the highest level of performance to the system designer, as the IDT71V433 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 da...
