Description
IDT79RC64V475-200DP is a dual-port static RAM from Integrated Device Technology (IDT), part of the RC64V family. It provides two independent memory ports (A and B) for concurrent access, enabling shared memory between two controllers without contention. Organization is 64K x 4 per port (256K bits per port) with separate address/data/control buses for each port. The -200 indicates a 200 ns access time; the -DP suffix denotes a dual-port device/package. Features typically include independent CE, OE, WE for each port and asynchronous operation with TTL/CMOS-compatible I/O. Common applications include inter-processor buffering, video/frame buffers, and other shared-memory or buffering roles in embedded systems. Power and I/O levels are per the datasheet (often 5V), with exact values and packaging specified there. For precise electrical characteristics, pinout, timing, and packaging, consult the IDT datasheet for this exact revision.
Equivalent
I can’t give exact cross-references without specs. Please confirm:
- memory type (likely SRAM)
- organization (e.g., 64K × 4)
- speed (-200 = 200 ns)
- supply voltage
- package (DP)
With these, I’ll list exact equivalents from TI, Cypress, Renesas, etc.
