PIC12CE673-04I/P Equivalent & Substitute Parts

Part Overview

The PIC12CE673-04I/P is an 8-bit microcontroller from Microchip Technology's PIC® 12C series, featuring 1.75KB OTP (One-Time Programmable) memory, 4MHz operation, and 5 I/O pins. This device is actively produced and widely used in embedded applications requiring low-cost, compact microcontroller solutions with permanent code storage.

Finding equivalent or substitute parts becomes necessary when the original part reaches end-of-life status, inventory constraints occur, or design requirements shift toward reprogrammable alternatives. The PIC12F675-I/P serves as the primary substitute, offering enhanced capabilities while maintaining pin-compatible packaging and core functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC12CE673-04I/P is determined by the following critical parameters:

• Package Compatibility: Both parts must use 8-DIP (0.300", 7.62mm) through-hole packaging to ensure direct PCB compatibility without layout modifications.
• Core Architecture: Both must be PIC 8-bit microcontrollers to maintain instruction set compatibility.
• Program Memory Size: Both must provide 1.75KB (1K x 14) program memory to accommodate existing firmware.
• I/O Pin Count: Both must feature 5 I/O pins for equivalent circuit integration.
• Supply Voltage Range: The substitute must support the 3V ~ 5.5V range or a compatible subset.
• Operating Temperature Range: The substitute must cover -40°C ~ 85°C or a compatible range.
• Compliance Standards: Both must maintain ROHS3 compliance and equivalent regulatory status.

The PIC12F675-I/P qualifies as a direct substitute based on these parameters. The primary difference is the program memory type (FLASH vs. OTP), which represents an enhancement rather than a limitation, as FLASH memory allows field reprogramming.

Parameter Comparison

Engineering Selection Recommendations

The PIC12F675-I/P is a qualified substitute for the PIC12CE673-04I/P based on the following engineering criteria:

Compliance & Regulatory Status: Both parts maintain ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), and REACH Unaffected status, ensuring equivalent regulatory standing for production and deployment.

Product Status: Both parts are actively produced by Microchip Technology, ensuring long-term availability and supply chain stability.

Pin-Compatible Packaging: The 8-DIP (0.300", 7.62mm) through-hole package is identical, allowing direct PCB substitution without layout modifications or rework.

Core Functionality Preservation: Identical program memory size (1.75KB), I/O pin count (5), and operating temperature range (-40°C ~ 85°C) ensure functional equivalence for existing designs.

Enhanced Capabilities: The PIC12F675-I/P provides FLASH memory (reprogrammable) instead of OTP, higher clock speed (20MHz vs. 4MHz), expanded EEPROM (128 x 8 vs. 16 x 8), and improved A/D resolution (10-bit vs. 8-bit). These enhancements do not create incompatibility; they expand design flexibility.

Supply Voltage Consideration: The PIC12F675-I/P supports a lower minimum voltage (2V vs. 3V), providing broader operational flexibility while remaining compatible with 3V ~ 5.5V designs.

Frequently Asked Questions (FAQ)

Q: Can the PIC12F675-I/P directly replace the PIC12CE673-04I/P on an existing PCB?

A: Yes. Both parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging with the same pin configuration. No PCB modifications are required for physical substitution.

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

A: The main difference is program memory type. The PIC12CE673-04I/P uses OTP (One-Time Programmable) memory, while the PIC12F675-I/P uses FLASH memory, which is field-reprogrammable. This is an enhancement, not a limitation.

Q: Will existing firmware compiled for the PIC12CE673-04I/P run on the PIC12F675-I/P?

A: Both parts share the same 1.75KB program memory size and PIC 8-bit core architecture. Firmware compatibility depends on specific instruction usage and peripheral differences. The higher clock speed (20MHz vs. 4MHz) and improved A/D resolution (10-bit vs. 8-bit) of the PIC12F675-I/P do not create incompatibility.

Q: Are there any voltage supply differences I should consider?

A: The PIC12F675-I/P supports 2V ~ 5.5V, while the PIC12CE673-04I/P requires 3V ~ 5.5V. If your design operates at 3V or higher, both parts are fully compatible. The PIC12F675-I/P offers additional flexibility for lower-voltage applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, MSL Level 1, and REACH Unaffected. They maintain equivalent regulatory and environmental compliance for production use.

Q: What about the RAM and EEPROM differences?

A: The PIC12CE673-04I/P has 128 x 8 RAM and 16 x 8 EEPROM, while the PIC12F675-I/P has 64 x 8 RAM and 128 x 8 EEPROM. For most applications using the full 1.75KB program memory, these differences are not limiting. The expanded EEPROM in the PIC12F675-I/P is beneficial for data storage applications.

Q: Is the PIC12F675-I/P suitable for production designs?

A: Yes. The PIC12F675-I/P is an active product from Microchip Technology with verified programmability and high inventory availability (59,200 pcs), ensuring reliable supply for production volumes.
