描述 Description

Functional Description
The GS881Z18B(T/D)/GS881Z32B(T/D)/GS881Z36B(T/D) is a 9Mbit Synchronous Static SRAM. GSI's 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.

特性 Features

• 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
• IEEE 1149.1 JTAG-compatible Boundary Scan
• On-chip write parity checking; even or odd selectable
• 2.5 V or 3.3 V +10%/–10% core power supply
• 2.5 V or 3.3 V I/O supply
• LBO pin for Linear or Interleave Burst mode
• Pin-compatible with 2M, 4M, and 18M devices
• Byte write operation (9-bit Bytes)
• 3 chip enable signals for easy depth expansion
• ZZ pin for automatic power-down
• JEDEC-standard packages
• Pb-Free 100-lead TQFP package available
