Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16LC57C-04I/P is determined by the following critical parameters:

• Core Processor & Architecture: Both main and substitute parts must be PIC architecture 8-bit microcontrollers
• Program Memory Size: Equivalent 3KB (2K x 12) memory capacity
• RAM Size: Matching 72 x 8 RAM configuration
• I/O Pin Count: Identical 20 I/O pins
• Package Type: 28-DIP through-hole package with 0.600" (15.24mm) spacing
• Operating Temperature Range: -40°C ~ 85°C compatibility
• Supply Voltage Range: Overlapping or compatible voltage specifications
• Compliance & Status: Active product status with ROHS3 compliance

The PIC16F57-I/P qualifies as a direct substitute based on matching core architecture, memory capacity, I/O configuration, package type, and compliance certifications. Differences in program memory type (FLASH vs. OTP) and maximum operating speed do not preclude substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16LC57C-04I/P and PIC16F57-I/P are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The PIC16F57-I/P offers higher maximum operating speed (20MHz vs. 4MHz) and FLASH memory (reprogrammable) versus OTP (one-time programmable), providing greater design flexibility. The PIC16LC57C-04I/P operates at lower minimum supply voltage (2.5V vs. 2V). Both devices share identical core architecture, memory capacity, I/O configuration, and package specifications, ensuring direct pin and functional compatibility within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the PIC16F57-I/P directly replace the PIC16LC57C-04I/P in existing designs?

A: Yes. Both devices share identical 28-DIP package pinout, 20 I/O pins, 3KB program memory capacity, 72 x 8 RAM, and -40°C to 85°C operating temperature range. Pin-for-pin compatibility is confirmed.

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

A: The PIC16LC57C-04I/P uses OTP (One-Time Programmable) memory with 4MHz maximum speed, while the PIC16F57-I/P uses FLASH memory with 20MHz maximum speed. FLASH memory allows multiple reprogramming cycles, whereas OTP allows single programming only.

Q: Are there supply voltage compatibility concerns?

A: The PIC16LC57C-04I/P operates at 2.5V to 5.5V, while the PIC16F57-I/P operates at 2V to 5.5V. The PIC16F57-I/P supports lower minimum voltage. Both are compatible with standard 3.3V and 5V supply rails.

Q: Do both parts meet current compliance requirements?

A: Yes. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. The PIC16F57-I/P is preferred for designs requiring reprogrammability or higher operating speed. The PIC16LC57C-04I/P is suitable for fixed-code applications where OTP memory is acceptable.
