Functional Description

The GS841Z18/36AT is a 4Mbit 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

? 256K x 18 and 128K x 36 configurations

? User-configurable Pipelined and Flow Through mode

? NBT (No Bus Turn Around) functionality allows zero wait

? Fully pin-compatible with both pipelined and flow through

NtRAM?, NoBL? and ZBT? SRAMs

? IEEE 1149.1 JTAG-compatible Boundary Scan

? 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

? Pb-Free 100-lead TQFP package available
