PIC16LC712-04/P Equivalent & Substitute Parts

Part Overview

The PIC16LC712-04/P is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, designed for embedded applications requiring low-power operation and basic control functionality. This device features 1.75KB of OTP (One-Time Programmable) memory, 128 bytes of RAM, and 13 I/O pins, operating at 4MHz with a supply voltage range of 2.5V to 5.5V. The product maintains Active status and is RoHS3 compliant. Alternative models become necessary when applications require higher processing speed, larger program memory capacity, or reprogrammable memory technology such as FLASH.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16LC712-04/P is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Core processor architecture (PIC family)
• Core size (8-Bit)
• Package type (18-DIP)
• Pin count and I/O configuration (13 I/O pins)
• RAM capacity (128 x 8 bytes minimum)
• Data converter specification (A/D 4x8b)
• Peripheral set (Brown-out Detect/Reset, POR, PWM, WDT)

Allowable Variations:

• Program memory size (may increase)
• Program memory type (OTP to FLASH conversion permitted)
• Operating speed (may increase)
• Supply voltage range (may expand)
• Operating temperature range (may expand)

The PIC16F716-I/P qualifies as a direct substitute based on identical pin configuration, I/O count, RAM capacity, peripheral set, and package specification, while offering enhanced capabilities in memory technology, speed, and temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16LC712-04/P and PIC16F716-I/P maintain Active product status and comply with RoHS3 and REACH regulations. The PIC16F716-I/P is suitable for applications requiring:

• Reprogrammable memory capability (FLASH vs. OTP)
• Higher processing speed (20MHz vs. 4MHz)
• Increased program memory capacity (4.6KB vs. 1.75KB)
• Extended operating temperature range (-40°C to 85°C vs. 0°C to 70°C)
• Lower minimum supply voltage (2V vs. 2.5V)

Pin-for-pin compatibility and identical peripheral configuration ensure direct substitution without circuit redesign. The expanded supply voltage range and temperature specification of the PIC16F716-I/P provide additional design flexibility for demanding environments.

Frequently Asked Questions (FAQ)

Q: Is the PIC16F716-I/P a direct pin-for-pin replacement for the PIC16LC712-04/P?

A: Yes. Both devices feature 18-DIP packaging with identical pin assignments, 13 I/O pins, and equivalent peripheral configurations. No circuit modifications are required for substitution.

Q: What are the primary differences between these devices?

A: The PIC16F716-I/P offers FLASH memory (reprogrammable) versus OTP (one-time programmable), operates at 5x higher speed (20MHz vs. 4MHz), provides double the program memory (4.6KB vs. 1.75KB), and supports an extended operating temperature range (-40°C to 85°C vs. 0°C to 70°C).

Q: Can the PIC16LC712-04/P be used in applications designed for the PIC16F716-I/P?

A: No. The PIC16LC712-04/P has lower speed and memory capacity, making it unsuitable for applications requiring the enhanced performance specifications of the PIC16F716-I/P.

Q: Are there any supply voltage compatibility concerns?

A: The PIC16F716-I/P operates at 2V minimum versus 2.5V for the PIC16LC712-04/P. Applications using supply voltages between 2V and 2.5V require the PIC16F716-I/P. Both devices support the full 5.5V maximum.

Q: What packaging options are available?

A: Both devices are supplied in 18-DIP (0.300", 7.62mm) through-hole packaging. The PIC16F716-I/P is available in Tube packaging.
