Functional Description
The CY7C1327B is a 3.3V, 256K by 18 synchronous-pipelined cache SRAM designed to support zero wait state secondary cache with minimal glue logic.

Features
• Supports 100-MHz bus for Pentium® and PowerPC™ operations with zero wait states
• Fully registered inputs and outputs for pipelined operation
• 256K by 18 common I/O architecture
• 3.3V core power supply
• 2.5V / 3.3V I/O operation
• Fast clock-to-output times
    — 3.5 ns (for 166-MHz device)
    — 4.0 ns (for 133-MHz device)
    — 5.5 ns (for 100-MHz device)
• User-selectable burst counter supporting Intel® Pentium interleaved or linear burst sequences
• Separate processor and controller address strobes
• Synchronous self-timed writes
• Asynchronous Output Enable
• JEDEC-standard 100 TQFP pinout
• “ZZ” Sleep Mode option and Stop Clock option
