PIC16C56T-XTE/SS Equivalent & Substitute Parts

Part Overview

The PIC16C56T-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 PIC16C56T-XTE/SS carries an Obsolete product status. Locating equivalent substitute parts is necessary for ongoing production support, maintenance applications, and design continuity where this controller remains specified in existing systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16C56T-XTE/SS is determined by strict alignment across the following critical parameters:

Core Functional Parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Program memory size (1.5KB / 1K x 12)
• Program memory type (OTP)
• RAM capacity (25 x 8)
• I/O pin count (12)
• Operating speed (4MHz)

Physical & Environmental Parameters:

• Package type (20-SSOP)
• Package dimensions (0.209", 5.30mm Width)
• Mounting type (Surface Mount)
• Operating temperature range compatibility
• Supply voltage range compatibility

Compliance & Certification:

• RoHS status (ROHS3 Compliant)
• REACH status (REACH Unaffected)

The substitute part PIC16C56-XTI/SS maintains identical core functionality, memory architecture, I/O configuration, and physical packaging. Substitution is valid where the operating temperature and supply voltage specifications of the application fall within the allowable ranges of both parts.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C56-XTI/SS qualifies as a direct substitute for the PIC16C56T-XTE/SS based on identical core architecture, memory configuration, I/O structure, and physical packaging.

Product Status Consideration: The substitute part carries Active product status, ensuring ongoing availability and manufacturing support from Microchip Technology, whereas the main part is Obsolete. This transition is appropriate for new production runs and long-term supply chain continuity.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying equivalent regulatory requirements.

Operating Range Differences: The substitute part specifies a maximum operating temperature of 85°C versus 125°C for the main part, and a supply voltage range of 3V to 6.25V versus 3.25V to 6V. Substitution is valid only where the application's operating temperature remains within -40°C to 85°C and supply voltage remains within 3V to 6.25V.

Frequently Asked Questions (FAQ)

Q: Can PIC16C56-XTI/SS replace PIC16C56T-XTE/SS in all applications?

A: Substitution is valid where the application operates within the temperature range of -40°C to 85°C and supply voltage range of 3V to 6.25V. If the original design requires operation above 85°C or below 3V, the substitute part is not suitable.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 20-SSOP package with identical dimensions of 0.209" width and 5.30mm overall width. PCB footprints and assembly processes are interchangeable.

Q: What is the significance of the product status change from Obsolete to Active?

A: The Active status of the substitute part indicates current manufacturing and distribution by Microchip Technology. This ensures component availability, technical support, and compliance with current manufacturing standards. The Obsolete status of the main part indicates it is no longer in production.

Q: Are the memory specifications identical?

A: Yes. Both parts feature 1.5KB (1K x 12) OTP program memory, 25 x 8 bytes of RAM, and 12 I/O pins. Firmware and application code are fully compatible.

Q: What are the key differences between these parts?

A: The primary differences are product status (Obsolete vs. Active), maximum operating temperature (125°C vs. 85°C), and supply voltage range (3.25V–6V vs. 3V–6.25V). Core functionality and packaging are identical.
