Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16C620T-20E/SS is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating speed (20MHz)
• Program memory capacity and type (896B OTP)
• RAM configuration (80 x 8)
• I/O pin count (13)
• Supply voltage range (3V ~ 6V)
• Package type and dimensions (20-SSOP)
• Peripheral feature set (Brown-out Detect/Reset, POR, WDT)

The PIC16C620-20I/SS qualifies as a direct substitute based on identical alignment across all critical electrical specifications and package requirements. The primary distinction lies in product status classification and operating temperature range, which do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C620-20I/SS is the active equivalent for the obsolete PIC16C620T-20E/SS. Both devices maintain identical electrical specifications, memory architecture, I/O configuration, and package form factor. The substitute part carries active product status with verified programmability through DiGi-Electronics, ensuring continued supply chain availability and manufacturing support.

The operating temperature range of the substitute part (-40°C ~ 85°C) is narrower than the main part (-40°C ~ 125°C). Applications requiring operation above 85°C must evaluate thermal management or seek alternative solutions. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity ratings, supporting standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can PIC16C620-20I/SS directly replace PIC16C620T-20E/SS in existing designs?

A: Yes, the PIC16C620-20I/SS provides direct functional substitution. Electrical specifications, memory configuration, I/O count, and package dimensions are identical. Verify that your application's maximum operating temperature does not exceed 85°C.

Q: What is the difference between the "T" and "I" designations in these part numbers?

A: The designations reflect different product status classifications and temperature ratings. The "T" variant (PIC16C620T-20E/SS) is obsolete with extended temperature range (-40°C ~ 125°C). The "I" variant (PIC16C620-20I/SS) is active with standard temperature range (-40°C ~ 85°C).

Q: Are both parts available in the same 20-SSOP package?

A: Yes. Both the PIC16C620T-20E/SS and PIC16C620-20I/SS use the 20-SSOP package with identical dimensions (0.209", 5.30mm Width), ensuring PCB layout compatibility without modification.

Q: What supply voltage range do these microcontrollers support?

A: Both parts operate across 3V to 6V supply voltage range, supporting single-cell lithium, dual-cell alkaline, or regulated power supplies within this specification.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain ROHS3 compliance and carry unlimited moisture sensitivity ratings (MSL 1). No compliance or certification differences exist between the two devices.
