Substitute Part Grouping Explanation

Substitution of the PIC16LC710-04I/P is determined by the following critical parameters:

• Package Compatibility: Both main and substitute parts must use 18-DIP (0.300", 7.62mm) through-hole packaging to ensure direct PCB compatibility without layout modifications.
• Core Architecture: Both parts must be PIC 8-bit microcontrollers to maintain instruction set compatibility and firmware portability.
• I/O Pin Count: Both parts must provide 13 I/O pins to support existing circuit designs.
• Peripheral Set: Both parts must include Brown-out Detect/Reset, PWM, and WDT functionality.
• Data Converter: Both parts must feature A/D 4x8b capability for analog signal processing.
• Compliance: Both parts must maintain RoHS3 and REACH compliance status.

The PIC16F716-I/P meets all substitution criteria and is classified as a direct equivalent within the PIC microcontroller family.

Parameter Comparison

Engineering Selection Recommendations

The PIC16F716-I/P is a direct substitute for the PIC16LC710-04I/P based on matching package, pin configuration, I/O count, and peripheral functionality. Both parts are active products with current manufacturing status and maintain identical RoHS3 and REACH compliance certifications.

Key differences between the parts are:

• Program Memory: The PIC16F716-I/P provides 4.6KB FLASH memory compared to 896B OTP on the PIC16LC710-04I/P, offering greater program storage capacity and reprogrammability.
• RAM: The PIC16F716-I/P includes 128 x 8 bytes of RAM versus 36 x 8 bytes, providing expanded data storage capability.
• Operating Speed: The PIC16F716-I/P operates at 20MHz versus 4MHz, enabling faster instruction execution.
• Supply Voltage Range: The PIC16F716-I/P operates from 2V to 5.5V, while the PIC16LC710-04I/P operates from 2.5V to 6V.
• Additional Peripheral: The PIC16F716-I/P includes Power-On Reset (POR) functionality.

Both parts maintain identical pin assignments, I/O configuration, and core peripheral set (Brown-out Detect/Reset, PWM, WDT, A/D 4x8b).

Frequently Asked Questions (FAQ)

Q: Can the PIC16F716-I/P be used as a direct replacement for the PIC16LC710-04I/P in existing designs?

A: Yes. Both parts share identical 18-DIP packaging, 13 I/O pins, and core peripheral functionality. Direct PCB substitution is possible without layout modifications. Firmware compatibility depends on application-specific code; the higher speed and expanded memory of the PIC16F716-I/P do not create incompatibilities with existing PIC16LC710-04I/P firmware.

Q: What are the key differences in memory architecture?

A: The PIC16LC710-04I/P uses 896B of OTP (One-Time Programmable) memory, which cannot be erased after programming. The PIC16F716-I/P uses 4.6KB of FLASH memory, which is reprogrammable. The PIC16F716-I/P also provides 128 x 8 bytes of RAM compared to 36 x 8 bytes on the PIC16LC710-04I/P.

Q: Are there supply voltage compatibility considerations?

A: The PIC16LC710-04I/P operates from 2.5V to 6V, while the PIC16F716-I/P operates from 2V to 5.5V. Applications using supply voltages between 2.5V and 5.5V are compatible with both parts. Applications requiring operation above 5.5V must use the PIC16LC710-04I/P.

Q: Do both parts maintain the same compliance certifications?

A: Yes. Both the PIC16LC710-04I/P and PIC16F716-I/P are RoHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the significance of the 4MHz versus 20MHz speed difference?

A: The PIC16F716-I/P operates at 5 times the clock speed of the PIC16LC710-04I/P. This enables faster instruction execution and reduced instruction cycle times. Applications designed for the PIC16LC710-04I/P will execute faster on the PIC16F716-I/P without timing conflicts, provided the application does not depend on specific clock frequency constraints.
