Key Parameters

Substitute Part Grouping Explanation

The PIC16F54-I/P qualifies as a direct substitute based on the following alignment of critical parameters:

Mechanical Compatibility: Both parts share identical 18-DIP packaging (0.300", 7.62mm) and Through Hole mounting, ensuring PCB layout compatibility without redesign.

Functional Equivalence: Both devices maintain 8-Bit core architecture, 768B program memory capacity (512 x 12), 25 x 8 RAM configuration, and 12 I/O pins. Peripheral sets are identical (POR, WDT).

Electrical Compatibility: The PIC16F54-I/P voltage supply range (2V ~ 5.5V) encompasses the PIC16LC54C-04/P requirement (2.5V ~ 5.5V), ensuring operation across the original specification.

Key Differentiators: The substitute features FLASH memory technology versus OTP, enabling reprogrammability. Operating speed increases to 20MHz (versus 4MHz), and temperature range extends to -40°C ~ 85°C, providing enhanced performance margins.

Compliance Alignment: Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical ECCN/HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16LC54C-04/P and PIC16F54-I/P maintain Active product status with verified programmability and full regulatory compliance (ROHS3, REACH Unaffected). Selection between these parts depends on application-specific requirements:

PIC16LC54C-04/P is appropriate for cost-optimized, single-program applications where OTP memory meets production requirements and the 4MHz speed satisfies timing constraints within the 0°C ~ 70°C operating window.

PIC16F54-I/P is suitable for applications requiring field reprogrammability, higher processing speed, or extended temperature operation. The FLASH memory technology and 20MHz capability provide design flexibility without mechanical or electrical redesign. The expanded voltage floor (2V minimum) and temperature range (-40°C ~ 85°C) accommodate broader environmental specifications.

Both parts are ROHS3 compliant and carry identical ECCN/HTSUS classifications, ensuring equivalent supply chain and regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can PIC16F54-I/P directly replace PIC16LC54C-04/P in existing PCB designs?

A: Yes. Both parts use identical 18-DIP packaging with 0.300" (7.62mm) pitch and Through Hole mounting. No PCB layout modifications are required. Pin assignments and electrical interface remain unchanged.

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

A: The main difference is program memory technology. PIC16LC54C-04/P uses OTP (One-Time Programmable) memory, while PIC16F54-I/P uses FLASH memory, enabling multiple reprogramming cycles. Both provide identical 768B capacity.

Q: Are there speed or temperature limitations when substituting?

A: No limitations exist. PIC16F54-I/P operates at 20MHz (versus 4MHz) and supports -40°C ~ 85°C (versus 0°C ~ 70°C). Applications designed for the original part will operate within these enhanced specifications without modification.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and share identical ECCN (EAR99) and HTSUS (8542.31.0001) classifications.

Q: What voltage range must be maintained for compatibility?

A: Both parts operate within 2.5V ~ 5.5V (the PIC16F54-I/P extends the lower limit to 2V). Applications designed for the original 2.5V ~ 5.5V range are fully compatible with the substitute.

Q: Are the peripheral sets identical?

A: Yes. Both parts include Power-On Reset (POR) and Watchdog Timer (WDT) peripherals with identical functionality and configuration.
