Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16C54-10E/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 768B OTP program memory (512 x 12 organization)
• RAM Capacity: 25 x 8 bytes
• I/O Count: 12 pins
• Operating Frequency: 10MHz
• Supply Voltage Range: 4.5V ~ 5.5V
• Package Type: 20-SSOP surface mount
• Peripheral Set: POR and WDT functionality

The substitute part PIC16C54-10I/SS maintains identical electrical and mechanical specifications with the exception of operating temperature range and product status. This part is actively manufactured and verified for programmability, making it a direct functional equivalent for applications within the overlapping temperature specification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C54-10I/SS is a direct substitute for the PIC16C54-10E/SS within the temperature range of -40°C to +85°C. Both parts maintain identical electrical specifications, memory organization, I/O configuration, and package geometry. The primary distinction is product status: the PIC16C54-10I/SS is actively manufactured by Microchip Technology, whereas the PIC16C54-10E/SS is obsolete.

For applications operating within the -40°C to +85°C temperature window, the PIC16C54-10I/SS provides equivalent functionality with the advantage of current production availability and verified programmability. Applications requiring operation above +85°C cannot use the substitute part and must pursue alternative solutions outside the PIC16C54 family.

Both parts carry ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the PIC16C54-10I/SS replace the PIC16C54-10E/SS in all applications?

A: The PIC16C54-10I/SS is functionally equivalent for applications operating within -40°C to +85°C. If your application requires operation above +85°C, the substitute part is not suitable.

Q: What is the difference between the -E and -I temperature grades?

A: The -E grade operates from -40°C to +125°C, while the -I grade operates from -40°C to +85°C. Both grades are otherwise electrically and mechanically identical.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the PIC16C54-10E/SS and PIC16C54-10I/SS use the 20-SSOP package with identical dimensions (0.209" width, 5.30mm).

Q: Is the PIC16C54-10I/SS currently available?

A: Yes. The PIC16C54-10I/SS is classified as active product status with current manufacturing availability.

Q: Do both parts have the same memory configuration?

A: Yes. Both parts feature 768B OTP program memory (512 x 12 organization), 25 x 8 bytes of RAM, and identical peripheral sets (POR, WDT).

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant with MSL 1 (unlimited) rating and identical REACH and ECCN classifications.
