PIC16CE623-20E/SS Equivalent & Substitute Parts

Part Overview

The PIC16CE623-20E/SS is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, designed for embedded applications requiring OTP (One-Time Programmable) memory. This device features 896B program memory, 128 x 8 EEPROM, and 13 I/O pins, operating at 20MHz with a supply voltage range of 3V to 5.5V. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Substitute Part Grouping Explanation

Substitution of the PIC16CE623-20E/SS is determined by strict alignment of the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 896B program memory (512 x 14), 128 x 8 EEPROM, 96 x 8 RAM
• Operating Speed: 20MHz
• I/O Count: 13 pins
• Supply Voltage Range: 3V ~ 5.5V
• Package: 20-SSOP form factor
• Peripherals: Brown-out Detect/Reset, POR, WDT

The PIC16CE623-20I/SS qualifies as a direct substitute based on identical core specifications, memory architecture, speed rating, I/O configuration, and package format. Differences in product status (obsolete vs. active) and operating temperature range do not affect functional substitution when thermal requirements of the application are within the substitute's specified limits.

Parameter Comparison

Engineering Selection Recommendations

The PIC16CE623-20I/SS is the direct substitute for the PIC16CE623-20E/SS. Both devices are ROHS3 compliant and carry identical moisture sensitivity ratings. The primary distinction is product status: the -20E/SS variant is obsolete while the -20I/SS is active in production. The -20I/SS operates within a narrower temperature range (-40°C to 85°C versus -40°C to 125°C), which must be evaluated against application thermal requirements. For systems operating exclusively within the -40°C to 85°C window, the -20I/SS provides full functional equivalence with the advantage of active manufacturer support and current availability.

Frequently Asked Questions (FAQ)

Q: Can the PIC16CE623-20I/SS directly replace the PIC16CE623-20E/SS in existing designs?

A: Yes, provided the application's operating temperature does not exceed 85°C. All functional parameters, memory architecture, I/O configuration, and package specifications are identical between the two variants.

Q: What is the significance of the temperature range difference?

A: The -20E/SS supports operation to 125°C while the -20I/SS is rated to 85°C. Applications requiring sustained operation above 85°C must retain the -20E/SS or identify alternative solutions. Applications operating within 0°C to 70°C ambient conditions will not be affected by this difference.

Q: Are both parts available in the same package?

A: Yes. Both the PIC16CE623-20E/SS and PIC16CE623-20I/SS use the 20-SSOP package with identical 0.209" width and 5.30mm dimensions, ensuring PCB layout compatibility.

Q: What does OTP memory mean for substitution purposes?

A: OTP (One-Time Programmable) memory cannot be erased or reprogrammed after initial programming. Both substitute parts use OTP technology, so programming must occur before component installation. This characteristic does not affect substitution compatibility.

Q: Are there compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. No compliance or certification barriers exist for substitution.

Q: Why is the -20E/SS listed as obsolete?

A: Obsolete status indicates Microchip Technology has discontinued production. The -20I/SS remains in active production, making it the preferred choice for new designs and ongoing system support.
