Substitute Part Grouping Explanation

Substitution eligibility for the PIC16LC65AT-04I/L is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Clock Speed: 4MHz operation
• Memory Configuration: 7KB OTP program memory (4K x 14), 192 x 8 RAM
• I/O Count: 33 I/O pins
• Peripheral Set: I2C, SPI, UART/USART connectivity with Brown-out Detect/Reset, POR, PWM, and WDT
• Voltage Range: 2.5V ~ 6V supply
• Package: 44-LCC (J-Lead) surface mount
• Thermal Range: -40°C ~ 85°C
• Compliance: ROHS3 Compliant, REACH Unaffected

The identified substitute maintains 100% electrical and mechanical compatibility with these parameters.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC65A-04I/L is a direct functional equivalent to the PIC16LC65AT-04I/L. Both devices share identical electrical specifications, memory configuration, peripheral functionality, and physical packaging.
