Description

This is a synchronous cache RAM, the model is CY7C1297F-117AC and the product category is IC chips. It is designed to interface with high-speed microprocessors with minimum glue logic.

Specifications and features

• 131,072 x 18 synchronous cache RAM
• Maximum access delay from clock rise is 6.5 ns (133-MHz version)
• A 2-bit on-chip counter captures the first address in a burst and increments the address automatically for the rest of the burst access.
• 3.3V –5% and +10% core power supply (VDD)
• 3.3V I/O supply (VDDQ)
• Fast clock-to-output times—6.5 ns (133-MHz version),7.5 ns (117-MHz version)
• Provide high-performance 2-1-1-1 access rate
• User-selectable burst counter supporting Intel® Pentium® interleaved or linear burst sequences
• Separate processor and controller address strobes
• Synchronous self-timed write
• Asynchronous output enable
• Supports 3.3V I/O level
• Offered in JEDEC-standard 100-pin TQFP
• “ZZ” Sleep Mode option

Application Scenarios

It can be used to store and retrieve data in various electronic products that require high-speed data access and processing, such as high-speed microprocessors.

Comparison

• Interface with high-speed microprocessors with minimum glue logic.
• Maximum Access Delay is 6.5 ns (133-MHz version) and 7.5 ns (117-MHz version) for fast clock-to-output times.
• High-performance 2-1-1-1 access rate.
• Can support Intel® Pentium® interleaved or linear burst sequences.

• Not suitable for lower-performance systems that do not require high-speed data access and processing.
