Engineering Selection Recommendations

All substitute parts maintain identical package geometry (20-TSSOP) and pinout compatibility with the PI6C48535-01LE, ensuring direct board-level replacement without layout modifications.

The 8535AG-01LF, 8535AG-01LFT, and 8535AGI-01LFT series from Renesas Electronics operate at 266 MHz maximum frequency. These parts are suitable for applications where the original 500 MHz specification exceeds system requirements. The 8535AGI-01LFT variant supports the full -40°C to 85°C operating temperature range, matching the original part's thermal specification.

The MC100ES6535EJ and MC100ES6535EJR2 series from Renesas Electronics provide 1 GHz maximum frequency capability, exceeding the original specification. These parts are appropriate for designs requiring higher clock distribution speeds or future performance headroom. Both variants maintain the -40°C to 85°C operating temperature range.

All substitute parts are ROHS3 compliant and maintain REACH unaffected status, consistent with the original part's regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 8535AG-01LF series be used as a direct replacement for the PI6C48535-01LE?

A: Yes, the 8535AG-01LF, 8535AG-01LFT, and 8535AGI-01LFT parts are pin-compatible and package-compatible substitutes. The 266 MHz frequency specification is lower than the original 500 MHz rating. Substitution is valid only if your application operates at or below 266 MHz. The 8535AGI-01LFT variant is preferred if your design requires the full -40°C to 85°C temperature range.

Q: What is the difference between 8535AG-01LF, 8535AG-01LFT, and 8535AGI-01LFT?

A: These parts are functionally identical with differences in packaging and temperature range. The 8535AG-01LF is supplied in bulk packaging. The 8535AG-01LFT is supplied in Tape & Reel format with a 0°C to 70°C operating temperature range. The 8535AGI-01LFT is supplied in Cut Tape and Digi-Reel format with a -40°C to 85°C operating temperature range, matching the original part's thermal specification.

Q: Should I use the MC100ES6535EJ or MC100ES6535EJR2 for new designs?

A: Both parts are functionally identical with 1 GHz frequency capability and -40°C to 85°C operating temperature range. The MC100ES6535EJR2 designation indicates a revised version. Both are active products suitable for new designs. The 1 GHz specification provides performance margin above the original 500 MHz requirement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original PI6C48535-01LE.

Q: What is the impact of the narrower supply voltage range on the Renesas substitutes?

A: The Renesas 8535A series specifies 3.135V to 3.465V supply voltage, compared to the original 3V to 3.6V range. The MC100ES6535 series specifies 3.135V to 3.8V. Verify that your power supply design operates within these narrower specifications before substitution. The MC100ES6535 series provides wider upper voltage tolerance.

Q: Can I use the MC100ES6535 series in applications originally designed for 500 MHz operation?

A: Yes. The MC100ES6535 series provides 1 GHz maximum frequency capability, which exceeds the original 500 MHz specification. This part is suitable for any application designed for the PI6C48535-01LE and provides additional performance margin for future design iterations.
