PIC16LC57CT-04/SS Equivalent & Substitute Parts

Part Overview

The PIC16LC57CT-04/SS is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 3KB OTP program memory, 72 x 8 bytes of RAM, and 20 I/O pins. Designed for embedded applications requiring low-power operation across a 2.5V to 5.5V supply range, this device operates at 4MHz with integrated Power-On Reset (POR) and Watchdog Timer (WDT) peripherals.

The PIC16LC57CT-04/SS is classified as obsolete. Identifying equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16LC57CT-04/SS is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: PIC processor family
• Core Size: 8-Bit processing capability
• Program Memory: 3KB (2K x 12) OTP configuration
• RAM Configuration: 72 x 8 bytes
• I/O Count: 20 pins minimum
• Operating Voltage Range: 2.5V ~ 5.5V compatibility
• Speed Rating: 4MHz operation
• Package Type: 28-SSOP form factor
• Peripherals: POR and WDT functionality

The substitute part PIC16LC57C-04/SS meets all these criteria, differing only in product status (Active vs. Obsolete) and programmability verification status. Both parts share identical electrical specifications, memory configuration, and physical packaging.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC57C-04/SS is the direct substitute for the PIC16LC57CT-04/SS. Both parts maintain identical electrical and mechanical specifications, ensuring functional compatibility in existing designs.
