Substitute Part Grouping Explanation

Substitution eligibility for the PIC16C55-RCE/SS is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: Must be PIC family
• Core Size: Must be 8-Bit
• Program Memory: Must be 768B (512 x 12) OTP
• RAM Configuration: Must be 24 x 8
• I/O Count: Must be 20 pins
• Speed: Must be 4MHz
• Package Type: Must be 28-SSOP with identical physical dimensions
• Peripherals: Must include POR and WDT
• Oscillator: Must support External oscillator type
• Supply Voltage Range: Must accommodate the operational range
• Compliance: Must maintain ROHS3 and REACH compliance status

The PIC16C55-RCI/SS qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while offering Active product status and verified programmability through DiGi-Electronics.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C55-RCI/SS is the qualified substitute for the obsolete PIC16C55-RCE/SS. Both parts maintain identical core functionality, memory configuration, I/O architecture, and package specifications. The PIC16C55-RCI/SS offers the advantage of Active product status, ensuring continued availability and supply chain support. Both devices are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The operating temperature range differs between the two parts: the main part supports -40°C to 125°C, while the substitute supports -40°C to 85°C. Supply voltage ranges show minor variation (3.25V–6V versus 3V–6.25V), both accommodating standard 5V and 3.3V logic levels. Applications requiring the extended upper temperature specification of the main part should evaluate thermal requirements against the substitute's 85°C maximum rating.

Frequently Asked Questions (FAQ)

Q: Can the PIC16C55-RCI/SS directly replace the PIC16C55-RCE/SS in existing designs?

A: Yes. Both parts share identical electrical specifications, memory architecture, I/O configuration, and 28-SSOP package dimensions. Pin-for-pin compatibility is maintained across all functional parameters.

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

A: The PIC16C55-RCE/SS is Obsolete, while the PIC16C55-RCI/SS is Active. The substitute offers verified programmability through DiGi-Electronics and improved supply availability. Operating temperature ranges differ slightly (125°C maximum versus 85°C maximum).

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. MSL ratings are identical at Level 1 (Unlimited moisture sensitivity).

Q: Does the package remain the same?

A: Yes. Both parts use the 28-SSOP package with identical physical dimensions (0.209" width, 5.30mm). PCB footprints and assembly processes remain unchanged.

Q: What should be considered when selecting between these parts?

A: For new designs or production requiring long-term availability, the PIC16C55-RCI/SS is the appropriate choice due to its Active status. For applications operating above 85°C ambient temperature, thermal performance must be evaluated against the substitute's maximum rating.
