PIC16CE623-20I/SO Equivalent & Substitute Parts

Part Overview

The PIC16CE623-20I/SO is an 8-bit microcontroller from Microchip Technology's PIC® 16C series, designed for embedded applications requiring OTP (One-Time Programmable) memory. This device operates at 20MHz with 896B of program memory and is housed in an 18-SOIC surface mount package. The product maintains active status with verified programmability through DiGi-Electronics.

Substitute parts become necessary when OTP memory limitations require reprogrammable alternatives, when higher I/O count is needed, or when FLASH memory technology is preferred over OTP for development and production flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16CE623-20I/SO is determined by the following critical parameters:

Core Compatibility Requirements:

• Processor family: PIC architecture
• Core size: 8-Bit
• Operating speed: 20MHz
• Package type: 18-SOIC surface mount
• Voltage supply range: 3V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C

Functional Flexibility Parameters:

• Program memory type: OTP or FLASH (FLASH provides reprogrammability advantage)
• Program memory size: Minimum 896B, larger sizes acceptable
• I/O count: Minimum 13, higher counts acceptable
• RAM size: Minimum 96 x 8, larger sizes acceptable
• EEPROM size: 128 x 8 (standard across series)

The PIC16F627A-I/SO qualifies as a direct substitute because it maintains identical core architecture, speed, package, voltage, and temperature specifications while offering FLASH memory technology and enhanced I/O and RAM capacity.

Parameter Comparison

Engineering Selection Recommendations

The PIC16F627A-I/SO is a qualified substitute for the PIC16CE623-20I/SO based on the following engineering criteria:

Electrical Compatibility: Both devices operate within identical voltage supply ranges (3V ~ 5.5V) and temperature specifications (-40°C ~ 85°C). Pin-to-pin compatibility is maintained through the 18-SOIC package standard.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring equivalent environmental and regulatory standing. Moisture sensitivity levels are identical at MSL 1 (Unlimited).

Functional Enhancement: The substitute provides increased program memory (1.75KB vs. 896B), expanded RAM (224 x 8 vs. 96 x 8), and additional I/O pins (16 vs. 13). These enhancements do not compromise compatibility and provide design flexibility for expanded functionality.

Memory Technology Advantage: FLASH memory in the PIC16F627A-I/SO enables field reprogrammability, eliminating the single-programming limitation of OTP technology while maintaining identical instruction set architecture and execution speed.

Product Status: Both devices maintain active product status with verified programmability, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can the PIC16F627A-I/SO directly replace the PIC16CE623-20I/SO in existing designs?

A: Yes. Both devices share identical core architecture, operating speed (20MHz), voltage supply range (3V ~ 5.5V), temperature range (-40°C ~ 85°C), and 18-SOIC package specifications. Pin assignments are compatible for standard applications.

Q: What is the primary advantage of substituting to the PIC16F627A-I/SO?

A: The PIC16F627A-I/SO uses FLASH memory technology, allowing unlimited reprogramming during development and production, compared to the single-programming limitation of OTP memory in the original device.

Q: Are there differences in I/O or memory capacity?

A: Yes. The PIC16F627A-I/SO provides 16 I/O pins versus 13 on the original, and 224 x 8 bytes of RAM versus 96 x 8 bytes. Program memory increases from 896B to 1.75KB. These enhancements are backward-compatible for designs not utilizing the additional resources.

Q: Do both devices require the same supply voltage?

A: Yes. Both operate across the identical voltage supply range of 3V to 5.5V, requiring no power supply modifications.

Q: Are there packaging or handling differences?

A: No. Both devices use the 18-SOIC surface mount package with identical moisture sensitivity levels (MSL 1, Unlimited), requiring identical handling and storage procedures.

Q: What is the oscillator configuration difference?

A: The original PIC16CE623-20I/SO requires an external oscillator, while the PIC16F627A-I/SO supports internal oscillator capability. External oscillator operation remains available on the substitute for designs already configured with external clock sources.

Q: Are both devices RoHS compliant?

A: Yes. Both devices are ROHS3 compliant and REACH unaffected, meeting identical environmental standards.
