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. 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. *This product is under development, is not qualified or characterized and is subject to change or cancellation without notice.

July 1999 Rev 1 3 White Electronic Designs Corporation * (602) 437-1520 * www.whiteedc.com White Electronic Designs PIN DESCRIPTIONS DIMM Pins 2, 87, 4, 89, 7, 92, 9, 94, 12, 96, 10, 93, 8, 91, 5, 88, 3, 86 Symbol A0-A17 Type Input Synchronous Description EDI2CG472256V ADVANCED Addresses: These inputs are registered and must meet the setup and hold times around the rising edge of CK. The burst counter generates internal addresses associated with A0 and A1, during burst and wait cycle. Byte Write: A byte write is LOW for a WRITE cycle and HIGH for a READ cycle. BW0/ controls DQ0-7 and DQP0, BW1# controls DQ8-15 and DQP1. BW2# controls DQ16-23 and DQP2. BW3# controls DQ24-31 and DQP3. BW4# controls DQ32-39 and DQP4. BW5# controls DQ40-47 and DQP5. BW6# controls DQ48-55 and DQP6. BW7# controls DQ56-64 and DQP7. Write Enable: This active LOW input gates byte write operations and must meet the setup and hold times around the rising edge of CK. 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. 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. Bank Enables: These active LOW inputs are used to enable each individual bank and to gate ADSP#. Output Enable: This active LOW asynchronous input enables the data output drivers. 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). 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. 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. 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. Snooze: These active HIGH inputs put the individual banks in low power consumption standby mode. For normal operation, this input has to be either LOW or NC (no connect). 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.
