Legacy DDR3 Supply Continuity for ATM and Inspection Equipment

ATM and X-ray inspection platforms remained on DDR3L under the supply arrangement agreed for the programme, avoiding the requalification associated with a memory generation change.

Compact embedded computing board

Application Overview

ATM and X-ray inspection platforms, qualified and certified on DDR3L and in active service.

Project Requirements

Migrating to a newer memory generation would have required revalidation and engineering effort on equipment whose value derives from remaining unchanged.

For high-precision and financial equipment, total cost is governed primarily by the avoidance of revalidation rather than by component price.

Project Configuration

DDR3L 1600 8GB, in both U-DIMM and SO-DIMM.

Project configuration as recorded for this programme. Current product availability is listed under Products.

Qualification & Implementation

  • Configuration held under a fixed bill of materials.
  • More than 50 critical tests completed for stability under continuous operation.
  • Legacy specifications supplied as current commitments rather than as remaining inventory.

Recorded Outcomes

Four years of stable supply extended the product life cycle by more than 50%. Maintenance cost was reduced by 30% through the elimination of revalidation and engineering effort, delivery held at 100% on components the wider market had begun to phase out, and the fixed bill of materials held procurement cost 15% lower through market instability. A recorded MTBF above two million hours corresponded to a zero downtime record.

Key Engineering Factors

Lifecycle Coordination

Legacy specifications supplied as current commitments over the committed programme period.

Configuration Control

A fixed bill of materials, so the certified configuration did not change without notice.

Revalidation Avoidance

Continuity on the qualified generation, removing the requalification the alternative would have required.
