Substitute Part Grouping Explanation

Substitution of the PIC16C716T-04E/SS is based on the following criteria:

Core Compatibility Parameters:

Identical core processor (PIC)
Identical core size (8-Bit)
Identical program memory size (4.6KB / 2K x 14)
Identical RAM size (128 x 8)
Identical number of I/O pins (13)
Identical peripheral set (Brown-out Detect/Reset, POR, PWM, WDT)
Identical data converter configuration (A/D 4x8b)
Identical package type (20-SSOP)
Compatible voltage supply range (substitute range must encompass or match the original)
Compatible operating temperature range

Allowable Variations:

Program memory type may differ (OTP to FLASH conversion allows reprogrammability)
Operating speed may increase (higher speed is backward compatible)
Voltage supply range may expand to lower minimum values (3V vs 4V)
Packaging format may differ (Tape & Reel vs bulk)

The PIC16F716T-E/SS qualifies as a direct substitute based on these parameters.

Engineering Selection Recommendations

The PIC16F716T-E/SS is a qualified substitute for the PIC16C716T-04E/SS based on the following engineering criteria:

Functional Equivalence: Both devices share identical core architecture, memory capacity, I/O configuration, and peripheral functionality. The 20-SSOP package ensures mechanical and electrical pin compatibility.

Compliance & Certification: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental and handling requirements.

Performance Enhancement: The substitute part operates at 20MHz versus 4MHz, providing increased processing capability without degrading system compatibility. The expanded voltage supply range (3V ~ 5.5V) offers greater design flexibility compared to the original 4V ~ 5.5V specification.

Memory Technology Advantage: The transition from OTP to FLASH memory enables field reprogrammability, eliminating the single-programming limitation of the original device while maintaining identical memory capacity.

Product Status: Both devices maintain Active product status from Microchip Technology, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can the PIC16F716T-E/SS be used as a direct replacement for the PIC16C716T-04E/SS in existing designs?

A: Yes. Both devices share identical pin configurations, package dimensions (20-SSOP), core architecture, memory size, I/O count, and peripheral set. No PCB modifications are required.

Q: What is the primary difference between these two parts?

A: The main difference is program memory type. The PIC16C716T-04E/SS uses OTP (One-Time Programmable) memory, while the PIC16F716T-E/SS uses FLASH memory, allowing multiple reprogramming cycles.

Q: Does the higher speed of the PIC16F716T-E/SS (20MHz vs 4MHz) affect compatibility?

A: No. Higher operating speed is backward compatible. Applications designed for 4MHz operation will function correctly at 20MHz. Timing-critical code may require adjustment to account for faster execution.

Q: Are there voltage supply considerations when substituting?

A: The PIC16F716T-E/SS supports a wider voltage range (3V ~ 5.5V) compared to the original (4V ~ 5.5V). Designs operating at 3V to 4V can only use the substitute part. Designs operating above 4V are compatible with both.

Q: What are the packaging differences?

A: The original part is supplied in standard packaging, while the substitute is available in Tape & Reel (TR) format. Both use identical 20-SSOP package geometry and are suitable for automated assembly.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, MSL ratings, REACH status, and ECCN classifications.
