Engineering Selection Recommendations

The PIC16C710-20I/SS is the direct functional equivalent of the PIC16C710-20E/SS. Both parts share identical electrical specifications, memory architecture, I/O configuration, and peripheral functionality. The primary distinction is product lifecycle status: the -20E/SS variant is obsolete, while the -20I/SS is actively manufactured and supported.

The -20I/SS variant carries verified programmability certification through DiGi-Electronics, confirming compatibility with standard development and programming workflows. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring equivalent handling and storage requirements.

The operating temperature range differs between the two variants: the main part supports -40°C to 125°C, while the substitute supports -40°C to 85°C. Applications requiring operation above 85°C must retain the original PIC16C710-20E/SS specification or identify alternative solutions outside this product family.

Frequently Asked Questions (FAQ)

Q: Can the PIC16C710-20I/SS directly replace the PIC16C710-20E/SS in existing designs?

A: Yes, for applications operating within the -40°C to 85°C temperature range. Both parts are pin-compatible, functionally identical, and share the same 20-SSOP package footprint. Code and firmware developed for the -20E/SS variant execute without modification on the -20I/SS.

Q: What is the significance of the temperature range difference?

A: The main part (PIC16C710-20E/SS) supports extended operation to 125°C, while the substitute (PIC16C710-20I/SS) is rated to 85°C. Applications requiring sustained operation above 85°C must use the original part specification or evaluate alternative microcontroller families.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant with identical moisture sensitivity levels (MSL 1, Unlimited). The substitute carries verified programmability certification, confirming compatibility with standard programming equipment and procedures.

Q: Why is the main part classified as obsolete?

A: Microchip Technology has transitioned the PIC16C710-20E/SS to obsolete status. The PIC16C710-20I/SS remains in active production and is the recommended solution for new designs and ongoing procurement.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 20-SSOP package with identical dimensions (0.209" width, 5.30mm). PCB footprints and mechanical assembly requirements are interchangeable.

Q: What inventory considerations apply?

A: The PIC16C710-20E/SS has 905 units in stock as new original inventory. The PIC16C710-20I/SS has 1135 units available. For long-term production, the active -20I/SS variant is the preferred procurement choice.
