Functional Description

The GS880Z18/36T is an 8Mbit Synchronous Static SRAM. GSIs NBT SRAMs, like ZBT, NtRAM, NoBL or other pipelined read/double late write or flow through read/single late write SRAMs, allow utilization of all available bus bandwidth by eliminating the need to insert deselect cycles when the device is switched from read to write cycles.

Features

• 512K x 18 and 256K x 36 configurations

• User configurable Pipeline and Flow Through mode

• NBT (No Bus Turn Around) functionality allows zero wait read-write-read bus utilization

• Fully pin compatible with both pipelined and flow through NtRAM™, NoBL™ and ZBT™ SRAMs

• Pin compatible with 2M, 4M and 16M (future) devices

• 3.3 V +10/–5 core power supply

• 2.5 V or 3.3 V I/O supply

• LBO pin for Linear or Interleave Burst mode

• Byte write operation (9-bit Bytes)

• 3 chip enable signals for easy depth expansion

• Clock Control, registered address, data, and control

• ZZ Pin for automatic power-down

• JEDEC-standard 100-lead TQFP package
