FEATURES
DESCRIPTION
4x256Kx72 Synchronous, Synchronous Burst
Flow-Through Architecture
Linear and Sequential Burst Support via MODE pin
Clock Controlled Registered Module Enable (EM#)
Clock Controlled Registered Bank Enables (E1#, E2#,

The EDI2CG472256VxxD2 is a Synchronous/Synchronous
Burst SRAM, 84 position Dual Key; Double High DIMM (168
contacts) Module, organized as 4x256Kx72. The Module
contains sixteen (16) Synchronous Burst Ram Devices,
packaged in the industry standard JEDEC 14mmx20mm
TQFP placed on a Multilayer FR4 Substrate. The module
architecture is defined as a Sync/Sync Burst, FlowThrough, with support for either linear or sequential burst.
This module provides High Performance, 2-1-1-1 accesses
when used in Burst Mode, and used as a Synchronous Only
Mode, provides a high performance cost advantage over
BiCMOS aysnchronous device architectures.
Aysnchronous Output Enable (G#)
Internally Self-timed Write
Individual Bank Sleep Mode enables (ZZ1, ZZ2, ZZ3, ZZ4)
Gold Lead Finish
3.3V +10%, - 5% Operation
Access Speed(s): TKHQV=9, 10, 12, 15ns
Common Data I/O
High Capacitance (30pf) drive, at rated Access Speed
Single Total Array Clock
Multiple Vcc and Gnd
Synchronous Only operations are performed via strapping
ADSC# Low, and ADSP# / ADV# High, which provides for
Ultra Fast Accesses in Read Mode while providing for
internally self-timed Early Writes.
Synchronous/Synchronous Burst operations are in relation
to an externally supplied clock, Registered Address,
Registered Global Write, Registered Enables as well as
an Asynchronous Output enable. This Module has been
defined with full flexibility, which allows individual control
of each of the eight bytes, as well as Quad Words in both
Read and Write Operations.

GW#
Input
Synchronous
Global Write: This active LOW input allows a full 72-bit WRITE to occur independent
of the BWE# and BWx# lines and must meet the setup and hold times around the
rising edge of CK.
101
CK
Input
Synchronous
Clock: This signal registers the addresses, data, chip enables, write control and
burst control inputs on its rising edge. All synchronous inputs must meet setup and
hold times around the clock’s rising edge.

111
ADV#
Input
Synchronous
Address Status Processor: This active LOW input is used to control the internal burst
counter. A HIGH on this pin generates wait cycle (no address advance).
27
ADSP#
Input
Synchronous
Address Status Processor: This active LOW input, along with EL# and EH# being
LOW, causes a new external address to be registered and a READ cycle is initiated
using the new address.
26
ADSC#
Input
Synchronous
Address Status Controller: This active LOW input causes device to be de-selected or
selected along with new external address to be registered.
A READ or WRITE cycle is initiated depending upon write control inputs.

DQ0-63
Input/Output
Data Inputs/Outputs: First byte is DQ0-7, second byte is DQ8-15, third byte is
DQ16-23, fourth byte is DQ24-31, fifth byte is DQ32-39, sixth byte is
DQ40-47, seventh byte is DQ48-55 and the eight byte is DQ56-64.
Parity Inputs/Outputs: DQP0 is parity bit for DQ0-7. DQP1 is parity bit for DQ8-15.
DQP2 is parity bit for DQ16-23. DQP3 is parity bit for DQ24-31. DQP4# is parity
bit for DQ-32-39. DQP5 is parity bit for DQ40-47. DQP6# is parity bit for DQ48-55.
DQP7 is parity bit for DQ56-64 and DQP7. In order to use the device configured as a
128K x 64, the parity bits need to be tied to VSS through a 10K ohm resistor.
Mode: This input selects the burst sequence. A LOW on this pin selects LINEAR
BURST. A NC or HIGH on this pin selects INTERLEAVED BURST.
