Description

The CY7C291A-35WMB is an asynchronous First-In-First-Out (FIFO) buffer memory from Cypress Semiconductors. It is a dual-ported RAM cell that has a capacity of 4,096 words with 9 bits wide, and operates at a speed of 50 MHz for both write and read, irrespective of its depth and width. This electronic component is available in PLCC, 7x7 TQFP, SOJ, 300-mil, and 600-mil DIP packages, and is also Pb-free. Furthermore, it is pin-compatible and functionally equivalent to IDT7200, IDT7201, IDT7202, IDT7203, IDT7204, AM7200, AM7201, AM7202, AM7203, and AM7204.
