data transfers
• 512 x 18-Bit - 512 x 18-Bit (IDT72511)
• 1024 x 18-Bit - 1024 x 18-Bit (IDT72521)
• 18-bit data buses on Port A side and Port B side
• Can be configured for 18-to-18-bit or 36-to-36-bit communication
• Fast 35ns access time
• Fully programmable standard microprocessor interface
• Built-in bypass path for direct data transfer between two
ports
• Two fixed flags, Empty and Full, for both the A-to-B and
the B-to-A FIFO
