Key Parameters

Substitute Part Grouping Explanation

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

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 1.5KB OTP program memory and 25 x 8 RAM
• I/O Count: 12 I/O pins
• Package Type: 20-SSOP form factor
• Supply Voltage: 4.5V ~ 5.5V operating range
• Peripherals: POR and WDT functionality
• Mounting: Surface mount technology

The substitute part PIC16C56-HSI/SS maintains identical core architecture, memory configuration, I/O count, package type, and supply voltage specifications. Differences in operating speed and temperature range do not preclude substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C56-HSI/SS serves as a direct substitute for the obsolete PIC16C56T-HSE/SS. Both devices share identical core architecture, memory configuration, I/O specifications, and package form factor. The substitute part carries Active product status, ensuring continued availability and supply chain reliability.

Key considerations for selection:

• Speed Upgrade: The substitute operates at 20MHz versus 16MHz, providing improved performance headroom without architectural changes.
• Temperature Range: The substitute supports -40°C to 85°C, which covers standard industrial and commercial operating conditions. Applications requiring the extended upper temperature range of 125°C must evaluate thermal requirements independently.
• Compliance: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental and handling characteristics.
• Programmability: The substitute is verified as programmable through DiGi-Electronics, confirming production readiness.

Frequently Asked Questions (FAQ)

Q: Can PIC16C56-HSI/SS directly replace PIC16C56T-HSE/SS in existing designs?

A: Yes. Both parts share identical core processor architecture, memory configuration (1.5KB OTP), I/O count (12 pins), package type (20-SSOP), and supply voltage range (4.5V ~ 5.5V). Pin-for-pin compatibility is maintained.

Q: What is the difference in operating speed between these parts?

A: The main part operates at 16MHz, while the substitute operates at 20MHz. The higher speed of the substitute does not create incompatibility; it provides additional performance margin. Applications designed for 16MHz operation will function correctly at 20MHz.

Q: Are there temperature range limitations with the substitute?

A: The main part supports -40°C to 125°C, while the substitute supports -40°C to 85°C. For applications requiring operation above 85°C, the temperature specification difference must be evaluated against actual thermal requirements.

Q: Do both parts use the same package and mounting technology?

A: Yes. Both parts use 20-SSOP surface mount packaging with identical physical dimensions (0.209" width, 5.30mm). PCB footprints and assembly processes are interchangeable.

Q: What is the significance of the product status difference?

A: The main part is classified as Obsolete, indicating discontinued production. The substitute is Active, ensuring ongoing availability, supply chain support, and manufacturing consistency.

Q: Are compliance certifications equivalent between these parts?

A: Yes. Both parts are ROHS3 compliant with identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), ensuring equivalent environmental and handling requirements.
