PIC16CE624-04I/P Equivalent & Substitute Parts

Part Overview

The PIC16CE624-04I/P is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 1.75KB of OTP (One-Time Programmable) memory, 13 I/O pins, and operation at 4MHz. This device is designed for embedded applications requiring low-cost, single-program deployment with integrated brown-out detection, power-on reset, and watchdog timer functionality. The part maintains active product status with verified programmability and full RoHS3 compliance.

Substitute parts are necessary when OTP memory limitations require reprogramming capability, when higher performance is needed, or when inventory constraints necessitate alternative sourcing from the same manufacturer's compatible product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16CE624-04I/P is determined by the following mandatory parameters:

• Core Processor: Must be PIC architecture
• Core Size: Must be 8-Bit
• Package Type: Must be 18-DIP (0.300", 7.62mm)
• Mounting Type: Must be Through Hole
• Voltage Supply Range: Must support 3V ~ 5.5V operation
• Operating Temperature: Must support -40°C ~ 85°C range
• Program Memory Size: Must be 1.75KB (1K x 14)
• Compliance: Must maintain RoHS3 compliance

The PIC16F627A-I/P qualifies as a direct substitute based on these parameters. While it features FLASH memory instead of OTP and offers enhanced performance characteristics, it maintains full compatibility across all mandatory electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16CE624-04I/P and PIC16F627A-I/P maintain active product status with verified programmability and full regulatory compliance (RoHS3, REACH Unaffected, EAR99 classification). Selection between these parts depends on application requirements:

The PIC16CE624-04I/P is appropriate for production-locked applications where code modification is not required post-deployment, leveraging OTP memory's cost efficiency for high-volume manufacturing.

The PIC16F627A-I/P is appropriate for applications requiring field reprogramming, development cycles, or prototype iterations, as FLASH memory permits multiple program cycles. The increased clock speed (20MHz versus 4MHz), expanded RAM (224 x 8 versus 96 x 8), and additional I/O pins (16 versus 13) provide enhanced performance headroom for complex applications within the same 18-DIP package footprint.

Both parts operate within identical voltage and temperature ranges, ensuring thermal and electrical compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the PIC16F627A-I/P directly replace the PIC16CE624-04I/P in existing PCB designs?

A: Yes. Both devices use the 18-DIP (0.300", 7.62mm) package with identical pin assignments for core functionality. Through-hole mounting is identical. Voltage supply requirements (3V ~ 5.5V) and operating temperature ranges (-40°C ~ 85°C) are fully compatible. No PCB modifications are required.

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

A: The PIC16CE624-04I/P uses OTP (One-Time Programmable) memory, which cannot be erased or reprogrammed after initial programming. The PIC16F627A-I/P uses FLASH memory, which supports multiple program-erase cycles, enabling field reprogramming and development flexibility.

Q: Are there performance differences?

A: The PIC16F627A-I/P operates at 20MHz compared to the PIC16CE624-04I/P's 4MHz, providing 5x faster instruction execution. The PIC16F627A-I/P also provides 224 x 8 bytes of RAM versus 96 x 8 bytes, and 16 I/O pins versus 13 I/O pins. Program memory size remains identical at 1.75KB.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is 1 (Unlimited) for both devices.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For production-locked applications where code does not require modification, the PIC16CE624-04I/P offers cost efficiency. For applications requiring reprogramming capability, development flexibility, or higher performance, the PIC16F627A-I/P is appropriate.
