PIC12C671-10/P Equivalent & Substitute Parts

Part Overview

The PIC12C671-10/P is an 8-bit microcontroller from Microchip Technology's PIC® 12C series, featuring 1.75KB OTP (One-Time Programmable) memory and operating at 10MHz. This device is designed for embedded applications requiring low-cost, compact microcontroller solutions with integrated analog-to-digital conversion capabilities. The product maintains Active status with verified programmability through DiGi-Electronics. Finding equivalent or substitute parts becomes necessary when OTP memory limitations require reprogrammable alternatives, when higher operating speed is required, or when extended temperature range operation is needed.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC12C671-10/P is determined by the following critical parameters:

• Core Processor Architecture: Must be PIC processor family to maintain instruction set compatibility
• Core Size: Must remain 8-Bit
• Program Memory Size: Must be 1.75KB (1K x 14) to accommodate existing firmware
• Number of I/O: Must provide minimum 5 I/O pins
• Package Type: Must be 8-DIP (0.300", 7.62mm) for mechanical compatibility
• Voltage Supply Range: Must support the 3V ~ 5.5V operating range
• Data Converters: Must include A/D conversion capability

The PIC12F675-I/P qualifies as a direct substitute based on these parameters. While it offers enhanced features (FLASH memory instead of OTP, higher speed, extended temperature range), it maintains full compatibility with the critical substitution criteria listed above.

Parameter Comparison

Engineering Selection Recommendations

The PIC12F675-I/P serves as a direct substitute for the PIC12C671-10/P based on maintained core architecture, identical I/O count, matching memory capacity, and compatible packaging. Both devices are ROHS3 compliant and carry MSL rating 1 (Unlimited), ensuring equivalent environmental and handling requirements.

The PIC12F675-I/P provides additional operational advantages including FLASH memory (enabling in-circuit reprogramming versus one-time programming), doubled clock speed (20MHz versus 10MHz), extended temperature range (-40°C to 85°C versus 0°C to 70°C), and enhanced analog resolution (10-bit versus 8-bit A/D conversion). The substitute maintains backward compatibility with the original device's instruction set and pin configuration.

Both devices are Active products with verified programmability status, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can the PIC12F675-I/P directly replace the PIC12C671-10/P in existing designs?

A: Yes. Both devices share identical core architecture (8-bit PIC processor), I/O pin count (5), program memory capacity (1.75KB), and 8-DIP package configuration. Pin-for-pin compatibility is maintained.

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

A: The main difference is program memory type. The PIC12C671-10/P uses OTP (One-Time Programmable) memory, while the PIC12F675-I/P uses FLASH memory, allowing multiple reprogramming cycles without device replacement.

Q: Are there voltage supply considerations when substituting?

A: The PIC12F675-I/P supports a lower minimum voltage (2V versus 3V). Both devices operate within the 3V to 5.5V range, so existing power supply designs remain compatible.

Q: Does the higher clock speed of the PIC12F675-I/P affect compatibility?

A: No. The substitute's 20MHz speed is backward compatible with designs using the 10MHz original device. Existing timing-dependent code will execute faster but remain functionally correct.

Q: Are there differences in analog-to-digital conversion specifications?

A: The PIC12F675-I/P provides 10-bit A/D resolution compared to the 8-bit resolution of the PIC12C671-10/P. This represents an enhancement and does not affect compatibility.

Q: What is the temperature range difference?

A: The PIC12F675-I/P operates from -40°C to 85°C, while the original operates from 0°C to 70°C. The substitute supports extended low-temperature operation.

Q: Are both devices RoHS compliant?

A: Yes. Both the PIC12C671-10/P and PIC12F675-I/P are ROHS3 compliant with MSL rating 1 (Unlimited), meeting equivalent environmental standards.
