Part Number: MSPM0G3507
Subject: MSPM0G3507SRG Qualification for −55°C to +125°C Operation (-EP Variant)
Hello TI Team,
We are evaluating the MSPM0G3507SRG family for use in an application requiring an operating temperature range of −55°C to +125°C.
We understand that the currently released MSPM0G3507 devices are specified for operation down to −40°C. We would like to understand the feasibility and requirements associated with qualifying an MSPM0G3507SRG device for operation over −55°C to +125°C, potentially as an Enhanced Product (-EP) offering.
Specifically, could you provide guidance on:
- Whether the current silicon has been characterized below −40°C.
- Which factors currently limit the published operating range to −40°C:
- Silicon characterization
- Flash memory retention/endurance
- Package qualification
- Production test coverage
- Reliability qualification constraints
- What additional qualification activities would be required to support a −55°C operating rating.
- Whether TI has any roadmap plans for an MSPM0G3507SRG device with -EP or military-temperature capability.
- Estimated business requirements for such a qualification effort:
- Minimum annual volume: 6,400/year (16 per aircraft, 400 aircrafts per year)
- NRE requirements:
- Customer sponsorship requirements:
- Expected qualification timeline:
Our application is aerospace-oriented and requires understanding whether extending the temperature range is primarily a qualification effort or whether there are underlying silicon limitations.
Thank you for your support.
