rail for proper operation. Asynchronous inputs include the

Features

Sleep mode enable (ZZ) and Output Enable. Output Enable can

be used to override the synchronous control of the output

drivers and turn the RAM's output drivers off at any time.

Write cycles are internally self-timed and initiated by the rising

edge of the clock input. This feature eliminates complex off-

chip write pulse generation required by asynchronous SRAMs

and simplifies input signal timing.

• 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

• 1.8 V or 2.5 V +10%/–10% core power supply

• 1.8 V or 2.5 V I/O supply

• User-configurable Pipeline and Flow Through mode

• 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

The GS880Z18/32/36CT-xxxIV may be configured by the

user to operate in Pipeline or Flow Through mode. Operating

as a pipelined synchronous device, meaning that in addition to

the rising edge triggered registers that capture input signals, the

device incorporates a rising-edge-triggered output register. For

read cycles, pipelined SRAM output data is temporarily stored

by the edge triggered output register during the access cycle

and then released to the output drivers at the next rising edge of

clock.

• JEDEC-standard 100-lead TQFP package

• RoHS-compliant 100-lead TQFP package available

Functional Description

The GS880Z18/32/36CT-xxxIV 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.

The GS880Z18/32/36CT-xxxIV is implemented with GSI's

high performance CMOS technology and is available in a

JEDEC-standard 100-pin TQFP package.

Because it is a synchronous device, address, data inputs, and

read/ write control inputs are captured on the rising edge of the

input clock. Burst order control (LBO) must be tied to a power
