Substitute Part Grouping Explanation

Substitution eligibility for the PIC16LC76-04I/SO is determined by the following critical parameters:

Core compatibility criteria:

• Identical core processor (PIC) and core size (8-Bit)
• Identical program memory size (14KB / 8K x 14)
• Identical RAM size (368 x 8)
• Identical number of I/O pins (22)
• Identical peripheral set (Brown-out Detect/Reset, POR, PWM, WDT)
• Identical connectivity interfaces (I2C, SPI, UART/USART)
• Identical package type and pinout (28-SOIC)
• Compatible operating temperature range (-40°C ~ 85°C)
• Compliant RoHS status (ROHS3)

Allowable variations:

• Program memory type (OTP to FLASH)
• Operating speed (4MHz to higher frequencies)
• Supply voltage range (2.5V ~ 6V to 2V ~ 5.5V)
• Data converter specifications (A/D resolution)

The PIC16LF76-I/SO qualifies as a direct substitute based on these criteria, offering enhanced programmability through FLASH memory and increased operating speed while maintaining full pin and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

PIC16LF76-I/SO as substitute for PIC16LC76-04I/SO:

The PIC16LF76-I/SO is a direct functional equivalent with enhanced capabilities. Both devices maintain Active product status from Microchip Technology and are ROHS3 compliant with identical MSL ratings. The substitute offers FLASH-based program memory in place of OTP, enabling field reprogramming and in-circuit updates. Operating speed increases from 4MHz to 20MHz, providing performance headroom for timing-critical applications.

The supply voltage range of the substitute (2V ~ 5.5V) is narrower than the main part (2.5V ~ 6V). Applications requiring operation below 2V or above 5.5V must retain the PIC16LC76-04I/SO. For designs operating within the 2V to 5.5V window, the PIC16LF76-I/SO provides superior programmability and performance characteristics while maintaining full pinout and functional compatibility.

Both devices are certified for identical operating temperature ranges and carry equivalent compliance certifications, ensuring regulatory and environmental consistency in system design.

Frequently Asked Questions (FAQ)

Q: Can PIC16LF76-I/SO replace PIC16LC76-04I/SO in existing designs?

A: Yes, the PIC16LF76-I/SO is pin-compatible and functionally equivalent. The 28-SOIC package, pinout, I/O count, peripheral set, and memory architecture are identical. No PCB modifications are required. Verify that your application's supply voltage operates within 2V to 5.5V, as the substitute has a narrower voltage range than the main part.

Q: What is the primary difference between these parts?

A: The main difference is program memory type: PIC16LC76-04I/SO uses OTP (One-Time Programmable) memory, while PIC16LF76-I/SO uses FLASH memory. FLASH memory allows multiple reprogramming cycles, enabling field updates and development flexibility. Additionally, the substitute operates at 20MHz versus 4MHz.

Q: Are there any compatibility concerns with the package?

A: No. Both parts use the 28-SOIC package with identical dimensions (0.295", 7.50mm width) and pinout. They are mechanically and electrically interchangeable at the PCB level.

Q: What supply voltage range should I use?

A: For the PIC16LC76-04I/SO, use 2.5V to 6V. For the PIC16LF76-I/SO substitute, use 2V to 5.5V. If your design requires operation below 2V or above 5.5V, the main part is required.

Q: Do both parts support the same peripherals and interfaces?

A: Yes. Both devices include identical peripheral sets (Brown-out Detect/Reset, POR, PWM, WDT) and connectivity interfaces (I2C, SPI, UART/USART). The 22 I/O pins and 5-channel 8-bit A/D converter are identical.

Q: What is the inventory status?

A: PIC16LC76-04I/SO has 838 pieces in stock. PIC16LF76-I/SO has 2230 pieces in stock, providing greater availability for procurement planning.
