Microcontrollers Procurement Notes

Verify the specific ordering suffix against the official Microchip datasheet DS30235 to ensure correct voltage range, temperature grade, and packaging configuration. Confirm that the '04' speed grade matches the system timing requirements. Check current production status as older variants may be subject to obsolescence notices.

Microcontrollers Selection Notes

Select this component when an 8-bit architecture with integrated ADC and standard serial interfaces is required. Ensure the 7 KB program memory capacity meets application code size needs. Verify that the 28-pin SOIC footprint fits the PCB layout constraints and that the 4 MHz operating speed satisfies real-time processing demands.

Microcontrollers Part Context

This part belongs to the PIC16C63A series, which are EPROM-based 8-bit microcontrollers. The 'L' designation indicates low-voltage capability, while '04' specifies the 4 MHz maximum clock frequency. The '/SO' suffix denotes the 28-pin Small Outline Integrated Circuit package type used in surface-mount assemblies.

Microcontrollers Replacement Considerations

Direct pin-compatible substitutes within the same family include PIC16C63A-04/P or PIC16C63A-04I/SO, provided voltage and temperature specifications align. Cross-family migration to PIC16F6xx series requires software adaptation due to architectural differences.
