PIC16C56T-10E/SS Equivalent & Substitute Parts

Part Overview

The PIC16C56T-10E/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. Operating at 10MHz with a supply voltage range of 4.5V to 5.5V, this device is housed in a 20-SSOP surface mount package. The main part is classified as obsolete, making equivalent substitutes necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PIC16C56T-10E/SS is determined by strict equivalence across the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating speed (10MHz)
• Program memory capacity and type (1.5KB OTP)
• RAM configuration (25 x 8)
• I/O pin count (12)
• Supply voltage range (4.5V ~ 5.5V)
• Package type and dimensions (20-SSOP)
• Peripheral set (POR, WDT)

The substitute part PIC16C56-10I/SS meets all these criteria and is therefore a direct functional equivalent. Differences in product status, temperature rating, and programmability verification do not affect electrical or mechanical compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C56-10I/SS is a direct substitute for the PIC16C56T-10E/SS. Both parts are ROHS3 compliant and carry identical MSL ratings. The substitute part holds active product status, ensuring continued availability and supply chain support compared to the obsolete main part.

The operating temperature range of the substitute (-40°C ~ 85°C) is narrower than the main part (-40°C ~ 125°C). Applications requiring operation above 85°C must evaluate this limitation against system thermal requirements. For standard industrial and commercial temperature ranges, this difference does not present a constraint.

Both parts share identical electrical specifications, memory architecture, I/O configuration, and package dimensions, enabling direct PCB-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can PIC16C56-10I/SS replace PIC16C56T-10E/SS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all functional parameters. PCB footprint, pinout, and electrical interface are identical. No design changes are required.

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

A: The suffix designations indicate different temperature ratings and product lifecycle status. The main part (T-10E) is obsolete with a -40°C to 125°C operating range. The substitute (10I) is active with a -40°C to 85°C operating range. All other specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 20-SSOP package with identical dimensions (0.209", 5.30mm width) and pinout configuration.

Q: Does the narrower temperature range of the substitute affect compatibility?

A: The substitute operates from -40°C to 85°C, compared to the main part's -40°C to 125°C range. For applications operating within -40°C to 85°C, there is no functional impact. Applications requiring sustained operation above 85°C must assess this specification against system requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both PIC16C56T-10E/SS and PIC16C56-10I/SS are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity).
