PIC16CE625-04E/SS Equivalent & Substitute Parts

Part Overview

The PIC16CE625-04E/SS is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, featuring 4.6KB OTP (One-Time Programmable) memory, 13 I/O pins, and operation across 3V to 5.5V supply voltage. The device is rated for -40°C to 125°C operating temperature and operates at 4MHz with integrated Brown-out Detect/Reset, Power-on Reset (POR), and Watchdog Timer (WDT) peripherals. This part maintains Active product status with verified programmability through DiGi-Electronics and full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications, package compatibility, and functional capabilities align with application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16CE625-04E/SS is determined by the following critical parameters:

Core Compatibility Parameters:

• 8-Bit core processor architecture (PIC family)
• 4.6KB (2K x 14) program memory capacity
• 20-SSOP surface mount package with identical 0.209" (5.30mm) width
• 3V to 5.5V supply voltage range
• -40°C to 125°C operating temperature range
• Active product status with current manufacturer support

Functional Equivalence Parameters:

• Integrated peripherals: Brown-out Detect/Reset, POR, WDT
• EEPROM: 128 x 8
• RAM: minimum 128 x 8
• Surface mount SSOP packaging

The PIC16F628A-E/SS qualifies as a direct substitute based on matching program memory capacity, identical package footprint, overlapping voltage and temperature specifications, and equivalent peripheral integration. Differences in program memory type (FLASH vs. OTP), speed rating, I/O count, and RAM capacity do not preclude substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC16CE625-04E/SS and PIC16F628A-E/SS maintain Active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these devices is based on application-specific requirements:

PIC16CE625-04E/SS is appropriate for applications where OTP (One-Time Programmable) memory is acceptable and lower speed operation (4MHz) meets functional requirements.

PIC16F628A-E/SS is appropriate for applications requiring FLASH memory (enabling in-circuit reprogramming), higher speed operation (20MHz), expanded I/O capability (16 pins vs. 13), and increased RAM (224 x 8 vs. 128 x 8). The FLASH memory type and higher speed rating provide enhanced flexibility for development and deployment scenarios.

Both devices share identical package footprint, supply voltage range, temperature rating, and core program memory capacity, enabling direct PCB-level substitution when electrical and functional requirements align.

Frequently Asked Questions (FAQ)

Q: Can PIC16F628A-E/SS directly replace PIC16CE625-04E/SS on the PCB?

A: Yes. Both devices use identical 20-SSOP surface mount packaging with matching pin pitch and footprint dimensions (0.209", 5.30mm width). No PCB layout modifications are required for physical substitution.

Q: What is the primary difference between OTP and FLASH memory types?

A: OTP (One-Time Programmable) memory in the PIC16CE625-04E/SS can be programmed once during manufacturing. FLASH memory in the PIC16F628A-E/SS supports multiple program/erase cycles, enabling in-circuit reprogramming and field updates.

Q: Are the supply voltage and temperature ratings identical?

A: Yes. Both devices operate across 3V to 5.5V supply voltage and -40°C to 125°C temperature range, ensuring equivalent environmental performance.

Q: Does the speed difference (4MHz vs. 20MHz) affect substitution?

A: Speed difference does not prevent substitution. The PIC16F628A-E/SS operates at higher speed, which is backward-compatible with applications designed for 4MHz operation. Applications requiring higher speed benefit from the PIC16F628A-E/SS upgrade.

Q: What about the I/O pin count difference (13 vs. 16)?

A: The PIC16F628A-E/SS provides three additional I/O pins within the same 20-SSOP package. Applications using only 13 I/O pins are unaffected. Applications requiring additional I/O benefit from the expanded capability.

Q: Are both devices currently available?

A: Yes. Both devices maintain Active product status with current manufacturer support and verified availability through authorized distributors.
