Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC12CE673-10I/P is based on the following criteria:

Compatible Parameters (Required for Substitution):

• Core Processor: PIC
• Core Size: 8-Bit
• Program Memory Size: 1.75KB (1K x 14)
• Number of I/O: 5
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Operating Temperature Range: -40°C ~ 85°C (TA)
• RoHS Status: ROHS3 Compliant

Allowable Variations:

• Program Memory Type: OTP to FLASH (FLASH provides reprogrammability advantage)
• Speed: 10MHz to 20MHz (higher speed is backward compatible)
• Voltage Supply Range: 3V ~ 5.5V to 2V ~ 5.5V (wider range is acceptable)
• Data Converters: A/D 4x8b to A/D 4x10b (higher resolution is acceptable)
• RAM Size: 128 x 8 to 64 x 8 (reduction acceptable if application permits)
• EEPROM Size: 16 x 8 to 128 x 8 (increase acceptable)

The PIC12F675-I/P qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC12CE673-10I/P and PIC12F675-I/P maintain Active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts is determined by application requirements:

Select PIC12CE673-10I/P when:

• OTP (One-Time Programmable) memory is specified for production cost optimization
• Operating voltage minimum of 3V is acceptable
• 10MHz processing speed meets application timing requirements
• 8-bit analog-to-digital conversion resolution is sufficient

Select PIC12F675-I/P when:

• FLASH memory reprogrammability is required for development, field updates, or production flexibility
• Extended voltage supply range (2V minimum) is beneficial for battery-powered applications
• 20MHz processing speed provides performance margin or faster execution
• 10-bit analog-to-digital conversion resolution improves measurement accuracy
• Increased EEPROM capacity (128 x 8 vs. 16 x 8) is required for data storage

Both devices share identical pin configuration, package dimensions, and thermal operating range, ensuring direct mechanical and electrical compatibility in 8-DIP through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can PIC12F675-I/P directly replace PIC12CE673-10I/P in existing designs?

A: Yes. Both devices use identical 8-DIP (0.300", 7.62mm) packaging with 5 I/O pins in the same configuration. Pin-for-pin compatibility is maintained. No PCB modifications are required.

Q: What is the primary difference between these microcontrollers?

A: The main difference is program memory technology. PIC12CE673-10I/P uses OTP (One-Time Programmable) memory, while PIC12F675-I/P uses FLASH memory, allowing multiple reprogramming cycles. PIC12F675-I/P also operates at 20MHz versus 10MHz and includes higher-resolution analog conversion (10-bit vs. 8-bit).

Q: Are there voltage supply compatibility concerns?

A: No. PIC12CE673-10I/P operates at 3V ~ 5.5V, and PIC12F675-I/P operates at 2V ~ 5.5V. The PIC12F675-I/P's wider voltage range is backward compatible with designs using the narrower 3V ~ 5.5V specification.

Q: Does the RAM size difference affect compatibility?

A: PIC12CE673-10I/P provides 128 x 8 RAM, while PIC12F675-I/P provides 64 x 8 RAM. Applications using less than 64 x 8 RAM will function identically. Applications requiring more than 64 x 8 RAM cannot use PIC12F675-I/P as a substitute.

Q: What are the EEPROM capacity differences?

A: PIC12CE673-10I/P includes 16 x 8 EEPROM, while PIC12F675-I/P includes 128 x 8 EEPROM. The increased capacity in PIC12F675-I/P provides additional non-volatile storage without affecting compatibility for applications using 16 x 8 or less.

Q: Are both devices RoHS and REACH compliant?

A: Yes. Both PIC12CE673-10I/P and PIC12F675-I/P are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For production designs where code is finalized and cost optimization is prioritized, PIC12CE673-10I/P is appropriate. For development, prototyping, or applications requiring field reprogrammability, PIC12F675-I/P is recommended due to FLASH memory and enhanced performance specifications.
