PIC16C56-XTE/SS Equivalent & Substitute Parts

Part Overview

The PIC16C56-XTE/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-cost, compact control logic, this device operates at 4MHz with an external oscillator and includes Power-On Reset (POR) and Watchdog Timer (WDT) peripherals.

The PIC16C56-XTE/SS carries an Obsolete product status. Locating equivalent substitute parts is necessary for ongoing production support, maintenance applications, and design continuity where this microcontroller was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16C56-XTE/SS is determined by strict alignment across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 1.5KB OTP program memory, 25 x 8 RAM
• I/O Count: 12 I/O pins
• Operating Speed: 4MHz
• Package Format: 20-SSOP surface mount
• Voltage Supply Range: Compatibility within specified Vcc/Vdd limits
• Operating Temperature Range: Functional performance across specified thermal envelope
• Peripheral Set: POR and WDT availability

The PIC16C56-XTI/SS qualifies as a direct substitute based on identical core architecture, memory, I/O configuration, speed, and package. Differences in product status (Active vs. Obsolete), voltage supply range tolerance, and maximum operating temperature do not prevent functional substitution in applications designed within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C56-XTI/SS is a qualified substitute for the PIC16C56-XTE/SS based on functional equivalence across all core electrical and mechanical parameters. Both devices share identical processor architecture, memory configuration, I/O capability, and package format.

The PIC16C56-XTI/SS carries Active product status, ensuring ongoing availability and manufacturing support from Microchip Technology. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, supporting equivalent supply chain and environmental requirements.

When selecting the PIC16C56-XTI/SS as a replacement, verify that the application's operating temperature requirement does not exceed 85°C, as the substitute part's maximum rated temperature is lower than the original specification. Additionally, confirm that the application's power supply voltage remains within the substitute part's specified range of 3V to 6.25V.

Frequently Asked Questions (FAQ)

Q: Can the PIC16C56-XTI/SS directly replace the PIC16C56-XTE/SS in existing designs?

A: Yes, the PIC16C56-XTI/SS is functionally equivalent across core parameters: processor architecture, memory size and type, I/O count, operating speed, and package format. Substitution is valid provided the application operates within the substitute part's voltage supply range (3V ~ 6.25V) and maximum temperature rating (85°C).

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

A: The main differences are product status and thermal/voltage specifications. The PIC16C56-XTE/SS is Obsolete with a wider operating temperature range (-40°C ~ 125°C) and voltage tolerance (3.25V ~ 6V). The PIC16C56-XTI/SS is Active with a narrower temperature range (-40°C ~ 85°C) and slightly extended voltage upper limit (6.25V).

Q: Are both parts available in the same package?

A: Yes, both the PIC16C56-XTE/SS and PIC16C56-XTI/SS are supplied in 20-SSOP surface mount packages with identical physical dimensions (0.209", 5.30mm width).

Q: Do these parts have the same memory and I/O specifications?

A: Yes, both parts feature identical 1.5KB OTP program memory, 25 x 8 bytes RAM, 12 I/O pins, and 4MHz operating speed.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant with MSL rating 1 (Unlimited moisture sensitivity). Both carry EAR99 export classification and are REACH unaffected.
