PIC16LC710-04/SO Equivalent & Substitute Parts

Part Overview

The PIC16LC710-04/SO is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, designed for embedded applications requiring low-power operation. This device features 896B of OTP (One-Time Programmable) memory, 13 I/O pins, and integrated peripherals including brown-out detection, PWM, and watchdog timer functionality. The part is currently in active production status with 2100 units in stock.

Substitute parts become necessary when OTP memory limitations require reprogramming capability, when operating temperature ranges must extend beyond 0°C to 70°C, or when higher clock speeds are required for performance-critical applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16LC710-04/SO is determined by the following criteria:

Core Compatibility Requirements:

• PIC core processor architecture
• 8-bit core size
• 13 I/O pins
• 4x8-bit A/D converter
• 18-pin package configuration

Allowed Parameter Variations:

• Program memory type may change from OTP to FLASH (enables reprogramming)
• Program memory size may increase (backward compatible for code storage)
• Operating clock speed may increase (maintains backward compatibility)
• Operating temperature range may expand (extends usable conditions)
• RAM size may increase (does not affect core functionality)
• Voltage supply range may narrow (must remain compatible with 2.5V minimum)

Non-Substitutable Parameters:

• Core processor type
• Core size (must remain 8-bit)
• I/O pin count
• Package pin count and type
• A/D converter configuration

The PIC16F716 series qualifies as a direct substitute based on these criteria, offering FLASH memory reprogrammability while maintaining identical I/O architecture and peripheral configuration.

Parameter Comparison

Engineering Selection Recommendations

PIC16F716-I/SO (18-SOIC Surface Mount)

This substitute maintains identical surface-mount packaging and footprint compatibility with the PIC16LC710-04/SO. The PIC16F716-I/SO is ROHS3 compliant and carries active product status. The FLASH memory type enables in-circuit reprogramming, eliminating the single-program limitation of OTP devices. The extended operating temperature range (-40°C to 85°C) supports industrial and automotive applications beyond the original part's specification. All compliance certifications (REACH Unaffected, EAR99 ECCN) match the original device.

PIC16F716-I/P (18-DIP Through Hole)

This substitute provides identical electrical functionality and I/O configuration but requires through-hole mounting. Selection of this variant is appropriate only when PCB design accommodates DIP packaging. The PIC16F716-I/P shares all compliance and active status attributes with the surface-mount variant.

Both PIC16F716 variants are suitable direct replacements from an electrical and functional standpoint, with selection determined by packaging and mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can PIC16F716 devices replace PIC16LC710-04/SO in existing designs?

A: Yes, for surface-mount applications, the PIC16F716-I/SO is a direct replacement. The identical 18-SOIC package, pin count, I/O configuration, and peripheral set ensure compatibility. Code written for PIC16LC710-04/SO executes on PIC16F716 without modification, as both devices share the same PIC core architecture and instruction set.

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

A: The PIC16LC710-04/SO uses OTP (One-Time Programmable) memory, allowing a single programming cycle during manufacturing. The PIC16F716 uses FLASH memory, enabling multiple reprogramming cycles in-circuit or in-system. This difference is significant for development, testing, and field updates.

Q: Are there voltage supply compatibility concerns?

A: The PIC16LC710-04/SO operates from 2.5V to 6V, while PIC16F716 operates from 2V to 5.5V. Designs operating at 2.5V or higher and 5.5V or lower are compatible with both devices. Designs requiring operation below 2V or above 5.5V cannot use PIC16F716 as a substitute.

Q: Does the higher clock speed of PIC16F716 (20MHz vs 4MHz) affect compatibility?

A: No. The PIC16F716 operates at a higher maximum clock speed but is fully backward compatible at lower speeds. Designs clocked at 4MHz or less operate identically on both devices. The higher speed capability of PIC16F716 is optional and does not require design changes.

Q: What packaging options are available?

A: The PIC16F716-I/SO maintains the original 18-SOIC surface-mount package. The PIC16F716-I/P provides the same functionality in an 18-DIP through-hole package for designs requiring through-hole mounting.

Q: Are compliance certifications equivalent?

A: Yes. Both PIC16F716 variants carry ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification, matching the original PIC16LC710-04/SO certifications.
