PIC16C57C-04E/SS Equivalent & Substitute Parts

Part Overview

The PIC16C57C-04E/SS is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 3KB of OTP (One-Time Programmable) memory, 20 I/O pins, and operation at 4MHz. The device is housed in a 28-SSOP surface mount package and operates across a supply voltage range of 3V to 5.5V with an extended temperature range of -40°C to 125°C.

This part is classified as obsolete. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design flexibility is required for new production runs. Substitute parts must maintain electrical compatibility across core parameters including memory architecture, I/O configuration, package form factor, and voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16C57C-04E/SS is determined by strict equivalence across the following critical parameters:

Memory Architecture: Program memory capacity (3KB OTP), memory organization (2K x 12), and RAM size (72 x 8) must be identical.

Processing Capability: Core processor type (PIC), core size (8-Bit), and clock speed (4MHz) must match exactly.

I/O Configuration: The number of I/O pins (20) and peripheral set (POR, WDT) must be preserved.

Electrical Specifications: Supply voltage range (3V ~ 5.5V) and oscillator type (External) must be compatible.

Physical Form Factor: Package type (28-SSOP) and dimensions (0.209", 5.30mm Width) must be identical for PCB compatibility.

Compliance: RoHS3 compliance and MSL rating (1) must be maintained.

The substitute part PIC16C57C-04I/SS meets all these criteria with one operational difference: the operating temperature range is -40°C to 85°C, which is narrower than the main part's -40°C to 125°C range.

Parameter Comparison

Engineering Selection Recommendations

PIC16C57C-04I/SS is the direct substitute for PIC16C57C-04E/SS based on electrical and mechanical equivalence. Both parts share identical memory architecture, I/O configuration, package form factor, and supply voltage specifications.

The substitute part carries Active product status, whereas the main part is Obsolete. This distinction is significant for long-term availability and supply chain planning.

The primary operational difference is the temperature range: the substitute operates from -40°C to 85°C, compared to the main part's -40°C to 125°C. Applications requiring operation above 85°C cannot use the substitute without thermal management modifications or alternative component selection.

Both parts maintain ROHS3 compliance and MSL rating of 1, ensuring compatibility with standard manufacturing and storage protocols.
