Features

processor interfaces. The pipelined burst architecture provides cost-

effective 3-1-1-1 secondary cache performance for processors up to

100 MHz.

◆

32K x 32 memory configuration

Supports high-performance system speed:

The IDT71V432 CacheRAM contains write, data, address, and

controlregisters.InternallogicallowstheCacheRAMtogenerateaself-

CommercialandIndustrial:

— 5ns Clock-to-DataAccess (100MHz)

— 6ns Clock-to-DataAccess (83MHz)

— 7ns Clock-to-DataAccess (66MHz)

Single-cycle deselect functionality (Compatible with

Micron Part # MT58LC32K32D7LG-XX)

LBO input selects interleaved or linear burst mode

Self-timed write cycle with global write control (GW), byte

write enable (BWE), and byte writes (BWx)
