Engineering Selection Recommendations
The C8051F007-GQ provides electrical and mechanical equivalence to the C8051F007 across all functional parameters. Key differentiation factors include:
Product Status: The C8051F007 is classified as Obsolete, while the C8051F007-GQ is designated Not For New Designs. This distinction reflects component lifecycle positioning rather than functional capability differences.
Compliance: The C8051F007-GQ achieves ROHS3 compliance and REACH Unaffected status, whereas the original C8051F007 is RoHS non-compliant. For applications requiring regulatory compliance with current environmental standards, the C8051F007-GQ is the appropriate selection.
Packaging: The C8051F007-GQ is supplied in Tray packaging, compared to unspecified packaging for the base part number.
Programmability Verification: The C8051F007-GQ carries verified programmability status through DiGi-Electronics, providing additional assurance for development and production workflows.
Frequently Asked Questions (FAQ)
Q: Can C8051F007-GQ directly replace C8051F007 in existing designs?
A: Yes. The C8051F007-GQ maintains identical electrical specifications, memory configuration, peripheral set, and 32-LQFP package format. Pin-for-pin compatibility is confirmed across all functional parameters.
Q: What is the significance of the product status difference between Obsolete and Not For New Designs?
A: Obsolete status indicates the C8051F007 is no longer manufactured or supported. Not For New Designs indicates the C8051F007-GQ remains available but is not recommended for new product development. Both designations reflect component lifecycle maturity rather than functional deficiency.
Q: Does the RoHS3 compliance of C8051F007-GQ affect electrical performance?
A: No. RoHS3 compliance reflects material composition and environmental standards adherence. Electrical performance, operating characteristics, and functional capabilities remain identical to the non-compliant variant.
Q: Are there packaging considerations when substituting C8051F007 with C8051F007-GQ?
A: The C8051F007-GQ is supplied in Tray packaging. Verify that your assembly and handling processes accommodate tray-packaged components. The 32-LQFP (7x7mm) package format remains unchanged.
Q: What memory and interface specifications must be matched for substitution?
A: Substitution requires matching 32KB Flash program memory, 2.25KB RAM, 4-channel 12-bit ADC, 2-channel 12-bit DAC, and support for SMBus, SPI, and UART/USART interfaces. The C8051F007-GQ meets all these requirements.
