PIC16LC710-04I/SO Equivalent & Substitute Parts

Part Overview

The PIC16LC710-04I/SO is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, designed for embedded applications requiring low-power operation and basic peripheral integration. This device features 896B of OTP (One-Time Programmable) memory, 36 x 8 bytes of RAM, and operates at 4MHz with a supply voltage range of 2.5V to 6V. The part is currently active in production and widely available with 2,124 units in stock.

Finding equivalent or substitute parts becomes necessary when OTP memory limitations require reprogramming capability, when higher performance is needed, or when supply chain constraints affect availability of the original part number.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Compatibility Parameters:

• Core processor family: PIC
• Core size: 8-Bit
• Package type: 18-SOIC
• Number of I/O pins: 13
• Data converter capability: A/D 4x8b
• Operating temperature range: -40°C ~ 85°C
• Peripheral set: Brown-out Detect/Reset, PWM, WDT

Flexible Parameters (allowing substitution):

• Program memory type (OTP to FLASH conversion)
• Program memory size (larger capacity acceptable)
• Speed (higher clock frequency acceptable)
• RAM size (larger capacity acceptable)
• Voltage supply range (compatible overlap required)

The PIC16F716-I/SO qualifies as a direct substitute because it maintains identical pin count, package format, I/O configuration, and peripheral functionality while offering enhanced memory technology and performance characteristics.

Engineering Selection Recommendations

The PIC16F716-I/SO is a qualified substitute for the PIC16LC710-04I/SO based on the following engineering criteria:

Electrical Compatibility: Both devices maintain identical core architecture, I/O pin configuration, and peripheral functionality. The voltage supply ranges overlap within the 2.5V to 5.5V window, ensuring safe operation in applications designed for the original part.

Package Compatibility: Both parts use the 18-SOIC package with identical physical dimensions (0.295", 7.50mm width), allowing direct PCB footprint compatibility without layout modifications.

Compliance Status: Both parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8542.31.0001) codes, ensuring regulatory equivalence.

Performance Enhancement: The PIC16F716-I/SO offers superior specifications including FLASH memory (versus OTP), 5x larger program memory capacity, 4.6x larger RAM, and 5x higher clock speed. These enhancements provide design flexibility without introducing compatibility constraints.

Production Status: Both devices maintain active production status with verified availability, ensuring long-term supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the PIC16F716-I/SO be used as a direct pin-for-pin replacement?

A: Yes. Both devices share identical 18-SOIC packaging, pin count (13 I/O), and peripheral configuration. No PCB modifications are required for physical substitution.

Q: What is the primary advantage of substituting to the PIC16F716-I/SO?

A: The PIC16F716-I/SO uses FLASH memory technology, enabling in-circuit reprogramming and field updates. The original PIC16LC710-04I/SO uses OTP memory, which is programmed once during manufacturing and cannot be modified.

Q: Are there voltage supply considerations when substituting?

A: The PIC16LC710-04I/SO operates at 2.5V to 6V, while the PIC16F716-I/SO operates at 2V to 5.5V. Applications using supply voltages between 2.5V and 5.5V are fully compatible. Applications requiring operation above 5.5V must retain the original part.

Q: Does the higher clock speed of the PIC16F716-I/SO affect power consumption?

A: The PIC16F716-I/SO operates at 20MHz versus 4MHz for the original part. Power consumption scales with clock frequency and application workload. Applications requiring low-power operation at fixed clock speeds should evaluate power profiles for the specific use case.

Q: Are the peripheral sets identical between these devices?

A: Both devices include Brown-out Detect/Reset, PWM, and WDT (Watchdog Timer). The PIC16F716-I/SO adds POR (Power-On Reset) functionality, which is a superset enhancement and does not affect compatibility.

Q: What is the memory capacity difference?

A: The PIC16LC710-04I/SO provides 896B program memory and 36 x 8 bytes RAM. The PIC16F716-I/SO provides 4.6KB program memory and 128 x 8 bytes RAM. Applications using less than 896B of program memory and 36 bytes of RAM will operate identically on the substitute part.

Q: Are both parts available in the same packaging options?

A: Both devices are supplied in 18-SOIC surface mount packages. The PIC16F716-I/SO is available in tube packaging, while the original part packaging specification was not provided. Confirm packaging requirements with your procurement process.
