Substitute Part Grouping Explanation

Substitution for the PIC16C56T-LPE/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Program Memory: 1.5KB OTP
• RAM: 25 x 8 bytes
• I/O Count: 12 pins
• Speed: 40MHz
• Package: 20-SSOP form factor
• Peripherals: POR and WDT functionality
• Supply Voltage Compatibility: Overlapping Vcc/Vdd ranges
• Operating Temperature Range: Compatible thermal specifications
• Compliance: ROHS3 and REACH status

The PIC16C56-LPI/SS qualifies as a direct substitute based on identical core specifications, matching package, and compatible electrical parameters. The primary distinction is product status: the substitute part is active, whereas the main part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C56-LPI/SS is a direct functional equivalent to the PIC16C56T-LPE/SS. Both parts share identical core architecture, memory configuration, I/O count, and package specifications. The substitute part carries active product status from Microchip Technology, ensuring ongoing availability and support compared to the obsolete main part.

Voltage supply range compatibility is maintained within the specified operating envelope. The substitute part supports 2.5V to 6.25V, which encompasses the main part's 2.5V to 6V range. Operating temperature specifications differ: the main part supports -40°C to 125°C, while the substitute supports -40°C to 85°C. Design applications requiring operation above 85°C must verify thermal requirements against the substitute part's maximum rating.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Moisture sensitivity level remains at MSL 1 (Unlimited) for both variants.

Frequently Asked Questions (FAQ)

Q: Can PIC16C56-LPI/SS replace PIC16C56T-LPE/SS in existing designs?

A: Yes. The PIC16C56-LPI/SS is functionally equivalent across all critical parameters: processor architecture, memory size and type, I/O count, speed, and package form factor. Verify that your application's operating temperature requirement does not exceed 85°C, as the substitute part's maximum operating temperature is lower than the main part.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and operating temperature range. The PIC16C56T-LPE/SS is obsolete with a -40°C to 125°C operating range, while the PIC16C56-LPI/SS is active with a -40°C to 85°C operating range. All functional specifications and package dimensions are identical.

Q: Are there any supply voltage compatibility concerns?

A: No. The substitute part's supply voltage range (2.5V to 6.25V) fully encompasses the main part's range (2.5V to 6V). Both parts operate within compatible electrical specifications.

Q: Is the 20-SSOP package identical between both parts?

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

Q: Do both parts meet current compliance standards?

A: Yes. Both the PIC16C56T-LPE/SS and PIC16C56-LPI/SS are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is MSL 1 (Unlimited) for both variants.

Q: What should I consider when selecting between these parts?

A: Select based on product availability and application thermal requirements. The substitute part (PIC16C56-LPI/SS) is active and recommended for new designs. If your application requires operation above 85°C, the main part's extended temperature range may be necessary, though availability as an obsolete part should be verified with your supplier.
