Substitute Part Grouping Explanation

Substitute parts for the PIC16C63AT-04E/SS are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or be compatible for substitution:

• Core Processor: PIC
• Core Size: 8-Bit
• Speed: 4MHz
• Program Memory Size: 7KB (4K x 14)
• Program Memory Type: OTP
• RAM Size: 192 x 8
• Number of I/O: 22
• Connectivity: I2C, SPI, UART/USART
• Peripherals: Brown-out Detect/Reset, POR, PWM, WDT
• Voltage - Supply (Vcc/Vdd): 4V ~ 5.5V
• Mounting Type: Surface Mount
• Package / Case: 28-SSOP (0.209", 5.30mm Width)

The PIC16C63A-04I/SS meets all electrical and mechanical compatibility requirements for direct substitution. Both devices share identical core architecture, memory configuration, I/O count, peripheral set, and package specifications. The primary differences are product status (Active vs. Obsolete) and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C63A-04I/SS is the direct substitute for the PIC16C63AT-04E/SS. Both devices are ROHS3 compliant and carry MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

The PIC16C63A-04I/SS holds Active product status, providing assured long-term availability and continued manufacturer support. The substitute part maintains full electrical and mechanical compatibility with identical core architecture, memory configuration, I/O specifications, and package form factor.

The operating temperature range of the substitute part (-40°C to 85°C) is narrower than the main part (-40°C to 125°C). Applications requiring operation above 85°C must retain the original PIC16C63AT-04E/SS specification or identify alternative solutions outside this product family.

Frequently Asked Questions (FAQ)

Q: Are the PIC16C63AT-04E/SS and PIC16C63A-04I/SS pin-compatible?

A: Yes. Both devices use the 28-SSOP package with identical pin assignments, I/O count (22), and peripheral configurations. Direct socket substitution is supported.

Q: What is the difference between the operating temperature ranges?

A: The PIC16C63AT-04E/SS operates from -40°C to 125°C, while the PIC16C63A-04I/SS operates from -40°C to 85°C. Applications operating above 85°C require the original part specification.

Q: Can I use the PIC16C63A-04I/SS as a drop-in replacement?

A: Yes, provided your application operates within the -40°C to 85°C temperature range. All electrical specifications, memory configuration, connectivity protocols, and peripheral functions are identical.

Q: Why is the original part obsolete?

A: The PIC16C63AT-04E/SS is classified as obsolete by Microchip Technology. The PIC16C63A-04I/SS represents the active equivalent within the PIC® 16C product family.

Q: Are both parts RoHS compliant?

A: Yes. Both the PIC16C63AT-04E/SS and PIC16C63A-04I/SS are ROHS3 compliant with MSL rating of 1 (Unlimited).
