Engineering Selection Recommendations

The 8T49N285A-999NLGI8 is an active product with extended product lifecycle support compared to the obsolete MPC93R52ACR2. Selection of this substitute is supported by:

Product Status: The substitute maintains active status with Renesas Electronics Corporation, ensuring continued availability and technical support.

Regulatory Compliance: Both devices share identical REACH and ECCN classifications, maintaining compliance posture in regulated applications.

Operational Envelope: The substitute's supply voltage range encompasses the original part's operating range, and its extended temperature range (-40°C to 85°C) provides broader environmental coverage than the original specification (0°C to 70°C).

Package Consideration: The substitute uses a 56-VFQFN package versus the original 32-LQFP package. PCB layout redesign is required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can the 8T49N285A-999NLGI8 directly replace the MPC93R52ACR2 without design changes?

A: No. While both devices are PLL Clock Generators from Renesas Electronics Corporation with compatible electrical parameters, the package change from 32-LQFP to 56-VFQFN requires PCB layout modification. Pin assignments and footprints differ between these packages.

Q: What are the key electrical compatibility factors for this substitution?

A: Supply voltage range overlap (3.135V to 3.465V), LVCMOS signal compatibility, single circuit configuration, and PLL with bypass functionality. The substitute's higher frequency capability (1GHz vs. 240MHz) and extended temperature range provide additional design margin.

Q: Does the substitute support the same input/output signal types?

A: The substitute supports LVCMOS as required by the original part. Additionally, it supports HCSL, LVDSM, LVHSTL, LVPECL, and Crystal inputs, plus HSCL, LVDS, and LVPECL outputs, providing greater signal interface flexibility.

Q: Are there any compliance or regulatory differences between these parts?

A: Both devices carry identical REACH Unaffected and EAR99 ECCN classifications. No regulatory compliance differences exist between the two parts.

Q: What is the primary limitation of this substitution?

A: Package form factor change necessitates PCB redesign. The 56-VFQFN package is larger than the 32-LQFP package, requiring verification of available board space and routing capability.
