PIC16C56-LPE/SS Equivalent & Substitute Parts

Part Overview

The PIC16C56-LPE/SS is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 1.5KB OTP program memory, 25 x 8 bytes of RAM, and 12 I/O pins. Designed for embedded applications requiring low-power operation across a -40°C to 125°C temperature range, this device integrates Power-On Reset (POR) and Watchdog Timer (WDT) peripherals in a 20-SSOP surface mount package.

The PIC16C56-LPE/SS carries an Obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for legacy systems.

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16C56-LPE/SS is determined by strict alignment of the following electrical and mechanical parameters:

Core Substitution Criteria:

• Identical core processor architecture (PIC)
• Matching core size (8-Bit)
• Identical program memory size (1.5KB OTP)
• Identical RAM configuration (25 x 8)
• Matching I/O pin count (12)
• Identical package type and footprint (20-SSOP)
• Compatible voltage supply range (minimum 2.5V, maximum ≥6V)
• Matching oscillator type (External)
• Identical peripheral set (POR, WDT)

The PIC16C56-LPI/SS qualifies as a direct substitute based on full alignment across all electrical specifications and mechanical packaging requirements. Both devices share identical memory architecture, I/O configuration, and peripheral functionality within their respective operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C56-LPI/SS is a qualified substitute for the obsolete PIC16C56-LPE/SS based on the following engineering factors:

Functional Equivalence: Both devices implement identical PIC 8-bit core architecture with matching memory configuration (1.5KB OTP program memory, 25 x 8 RAM), I/O pin count (12), and peripheral set (POR, WDT). Pin-for-pin compatibility is maintained within the 20-SSOP package.

Compliance Alignment: Both parts maintain ROHS3 compliance and identical electrical specifications across core operating parameters. The substitute device extends the maximum supply voltage specification to 6.25V, providing enhanced margin for applications operating near the upper voltage boundary.

Supply Chain Advantage: The PIC16C56-LPI/SS carries Active product status with verified availability (995 pcs in stock), compared to the Obsolete status of the main part. This ensures long-term procurement reliability and design continuity.

Temperature Range Consideration: The substitute device specifies a narrower operating temperature range (-40°C to 85°C versus -40°C to 125°C). Applications requiring operation above 85°C must evaluate this limitation against specific thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the PIC16C56-LPI/SS directly replace the PIC16C56-LPE/SS in existing designs?

A: Yes, for applications operating within the -40°C to 85°C temperature range. Both devices share identical core architecture, memory configuration, I/O pin count, and package footprint. The substitute device is pin-compatible and functionally equivalent across all specified electrical parameters.

Q: What is the primary difference between these two part numbers?

A: The primary differences are product status and operating temperature range. The PIC16C56-LPE/SS is Obsolete with a -40°C to 125°C operating range, while the PIC16C56-LPI/SS is Active with a -40°C to 85°C range. The substitute also specifies a slightly higher maximum supply voltage (6.25V versus 6V).

Q: Are there any package or footprint differences?

A: No. Both devices use identical 20-SSOP surface mount packaging with 0.209" width and 5.30mm body dimensions. PCB layout and assembly processes require no modification.

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

A: Confirm that your application's maximum operating temperature does not exceed 85°C. If sustained operation above 85°C is required, the PIC16C56-LPI/SS is not suitable. Verify that your power supply design accommodates the extended voltage range (up to 6.25V) if operating near the upper boundary.

Q: Is the PIC16C56-LPI/SS available in the same programming format?

A: Both devices use OTP (One-Time Programmable) memory with identical 1.5KB capacity and 1K x 12 organization. Programming procedures and memory architecture are equivalent.
