ADVANCED*
16MB (4x512Kx72) SYNC / SYNC BURST,
DUAL KEY DIMM SRAM MODULE
FEATURES
DESCRIPTION
4x512Kx72 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#,
E3#, E4#)
Clock Controlled Byte Write Mode Enable (BWE#)
Clock Controlled Byte Write Enables (BW1# - BW8#)
Clock Controlled Registered Address
Clock Controlled Registered Global Write (GW#)
Asynchronous Output Enable (G#)
The WED2CG472512V is a Synchronous/Synchronous
Burst SRAM, 84 position Dual Key; Double High DIMM
(168 contacts) Module, organized as 4x512Kx72. 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/SyncBurst,
Flow-Through, with support for either linear or sequential
burst. This Module provides high performance, 2-1-1-1
accesses when used in Burst Mode, and when used in
Synchronous Only Mode, provides a high performance
cost advantage over BiCMOS asynchronous device
architectures.
Internally Self-Timed Write
Individual Bank Sleep Mode Enables (ZZ1, ZZ2, ZZ3, ZZ4)
Gold Lead Finish
3.3V ± 10% Operation
Frequency(s): 100, 83, 67, 50MHz
Access Speed(s): tKHQV = 7.5, 9, 10, 12, 15ns
Common Data I/O
High Capacitance (30pF) Drive, at Rated Access Speed
Single Total Array Clock
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.
