PIC16LC57C-04/P Equivalent & Substitute Parts

Part Overview

The PIC16LC57C-04/P is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 3KB OTP (One-Time Programmable) memory and operating at 4MHz. This device is designed for embedded applications requiring low-cost, single-program deployment with 20 I/O pins and integrated peripherals including Power-On Reset (POR) and Watchdog Timer (WDT). The part maintains Active product status with verified programmability through DiGi-Electronics. Equivalent substitute parts are identified for applications where alternative memory technologies, extended operating ranges, or higher performance specifications are required.

Key Parameters

Substitute Part Grouping Explanation

The PIC16F57-I/P qualifies as a direct substitute based on the following alignment of critical parameters:

Matching Parameters:

• Manufacturer: Microchip Technology (same source)
• Core Processor: PIC (identical architecture)
• Core Size: 8-Bit (identical bit width)
• Program Memory Size: 3KB (2K x 12) (identical capacity)
• RAM Size: 72 x 8 (identical memory configuration)
• Number of I/O: 20 (identical I/O count)
• Peripherals: POR, WDT (identical peripheral set)
• Package / Case: 28-DIP (0.600", 15.24mm) (identical physical form factor)
• Mounting Type: Through Hole (identical mounting method)
• RoHS Status: ROHS3 Compliant (equivalent compliance)

Differing Parameters:

• Program Memory Type: FLASH (vs. OTP in main part)
• Speed: 20MHz (vs. 4MHz in main part)
• Voltage - Supply: 2V ~ 5.5V (vs. 2.5V ~ 5.5V in main part)
• Operating Temperature: -40°C ~ 85°C (vs. 0°C ~ 70°C in main part)

The substitution is valid where the application permits FLASH memory reprogrammability, higher clock frequency, extended voltage range, or wider operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16LC57C-04/P and PIC16F57-I/P maintain Active product status from Microchip Technology and comply with ROHS3 and REACH requirements. Selection between these parts depends on application-specific requirements:

The PIC16LC57C-04/P is appropriate for applications with fixed, single-program deployment where OTP memory is acceptable and operating conditions remain within 0°C to 70°C and 2.5V to 5.5V specifications.

The PIC16F57-I/P is appropriate for applications requiring field reprogrammability through FLASH memory, higher processing speed (20MHz vs. 4MHz), extended operating temperature range (-40°C to 85°C), or lower minimum supply voltage (2V vs. 2.5V). Both devices share identical pinout, I/O count, memory capacity, and peripheral configuration, ensuring direct functional compatibility within the specified parameter ranges.

Frequently Asked Questions (FAQ)

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

A: Yes, provided the application does not depend on OTP memory characteristics. Both parts share identical pinout (28-DIP), I/O configuration (20 pins), memory capacity (3KB program, 72 x 8 RAM), and peripheral set (POR, WDT). The PIC16F57-I/P offers FLASH memory instead of OTP, enabling field reprogramming.

Q: What are the key differences between these parts?

A: The primary differences are program memory type (OTP vs. FLASH), maximum clock speed (4MHz vs. 20MHz), operating temperature range (0°C–70°C vs. -40°C–85°C), and minimum supply voltage (2.5V vs. 2V). All other functional parameters are identical.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both PIC16LC57C-04/P and PIC16F57-I/P are ROHS3 Compliant and REACH Unaffected.

Q: Does the package form factor differ between these parts?

A: No, both parts use identical 28-DIP (0.600", 15.24mm) through-hole packaging, ensuring mechanical compatibility on PCBs designed for either device.

Q: Which part should be selected for applications requiring temperature extremes?

A: The PIC16F57-I/P supports -40°C to 85°C operating temperature, compared to 0°C to 70°C for the PIC16LC57C-04/P. Applications requiring operation below 0°C or above 70°C must use the PIC16F57-I/P.
