Description

The CXK77V3211Q is a 32K × 32 high performance synchronous SRAM with a 2-bit burst counter and output register. All synchronous inputs pass through register controlled by a positive-edge-triggered single clock input (CLK).

Features

• Fast address access times and High frequency operation

• 5V tolerant inputs except I/O pins

• A FT pin for pipelined or flow-thru architecture

• A LBO mode pin as burst control pin (i486/Pentium™ and Linear burst sequence)

• Single +3.3V power supply

• Common data inputs and data outputs

• All inputs and outputs are LVTTL compatible

• Four Individual BYTE WRITE enables, GLOBAL WRITE and BYTE WRITE ENABLE

• Three Chip Enables for simple depth expansion

• One cycle output disable for both pipelined and flow-thru operation

• Internal input registers for address, data and control signals

• Self-timed WRITE cycle

• Write pass through capability

• High 30pF output drive capability at rated access time

• A ZZ pin for powerdown

• 100-lead QFP package for high density, high speed operation +10 – 5
