Substitute Part Grouping Explanation

Substitution eligibility for the PIC16C57-LPE/P is determined by strict alignment of the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 3KB (2K x 12) OTP program memory and 72 x 8 RAM
• I/O Count: 20 I/O pins
• Peripheral Set: POR (Power-On Reset) and WDT (Watchdog Timer)
• Package Type: 28-PDIP form factor
• Speed Rating: 40MHz maximum operating frequency
• Supply Voltage Range: Compatibility within specified Vcc/Vdd limits
• Compliance: ROHS3 compliance and REACH unaffected status

The PIC16C57-LPI/P meets all substitution criteria, maintaining identical core functionality, memory architecture, I/O configuration, and physical packaging while offering active product status.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C57-LPI/P is the direct substitute for the obsolete PIC16C57-LPE/P. Both devices maintain identical core functionality, memory architecture, I/O configuration, and physical packaging. The substitute part carries active product status from Microchip Technology, ensuring continued availability and manufacturing support.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The PIC16C57-LPI/P operates within a marginally extended supply voltage range (2.5V ~ 6.25V versus 2.5V ~ 6V) and a reduced operating temperature range (-40°C ~ 85°C versus -40°C ~ 125°C). These parameter variations do not affect substitution eligibility for applications operating within the substitute part's specified limits.

Frequently Asked Questions (FAQ)

Q: Can the PIC16C57-LPI/P directly replace the PIC16C57-LPE/P in existing designs?

A: Yes. Both parts share identical core architecture, memory configuration, I/O count, peripheral set, and 28-PDIP package. Direct pin-for-pin and functional substitution is supported.

Q: What is the difference between the PIC16C57-LPE/P and PIC16C57-LPI/P?

A: The primary differences are product status (obsolete versus active) and operating parameter ranges. The PIC16C57-LPI/P supports a supply voltage range of 2.5V ~ 6.25V and operating temperature range of -40°C ~ 85°C, compared to 2.5V ~ 6V and -40°C ~ 125°C for the main part. Both devices are functionally equivalent for applications within the substitute part's specified operating envelope.

Q: Are there any package or pinout differences?

A: No. Both parts use the 28-DIP (0.600", 15.24mm) package with identical pinout and mechanical dimensions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PIC16C57-LPE/P and PIC16C57-LPI/P are ROHS3 compliant and REACH unaffected.

Q: What should I verify before implementing the substitute part?

A: Confirm that your application's operating voltage and temperature requirements fall within the PIC16C57-LPI/P's specified ranges (2.5V ~ 6.25V supply voltage and -40°C ~ 85°C operating temperature).
