Power and energy monitoring
The ADC and control peripherals support supervisory measurement, fault response and waveform-related tasks.
Appliance and consumer control
A 20-pin form factor supports compact boards with moderate I/O and communication requirements.
Design and Procurement Advantages
• 28 KB Flash, 2 KB SRAM and EEPROM in a compact pin-count class.
• 12-bit ADCC supports more capable measurement and post-processing.
• Configurable logic and waveform peripherals reduce CPU intervention.
• Manufacturer Focus, Functional Safety Support and automotive positioning aid targeted promotion.
Package and Ordering-Code Guidance
The base name PIC16F18146 is not a complete purchasing code. Package, temperature grade, qualification level and packing method can change the orderable suffix and commercial availability.
1. Quote the complete manufacturer orderable part number, not only the base device name.
2. Confirm package, temperature grade, packing method and required compliance documentation.
3. For migration projects, verify pin functions, configuration bits, voltage behavior, peripherals and firmware changes.
4. Agree acceptable lot/date-code range and traceability requirements before order confirmation.
Lifecycle and Market Position
Microchip displayed PIC16F18146 as In Production and as a Focus product on the review date. Exact industrial or automotive order codes, package availability and lead time remain quotation-specific.
Alternative and Migration Options
Migration note |
• PIC16F18126 when a smaller family member is sufficient.
• PIC16F18156 or PIC16F18176 when more I/O is required.
• PIC16F17146 when an integrated op amp is important to the signal chain.
• PIC16F18446 for another low-pin-count full-featured device with a mature application ecosystem.
Alternative devices are comparison starting points only. They are not automatically pin-compatible or firmware-compatible. The final choice must be validated against electrical, mechanical, software, safety and regulatory requirements.
Sourcing and Quality Checklist
• Confirm manufacturer, complete ordering code, requested quantity and annual usage.
• Review current product status, PCNs, errata and customer-specific qualification requirements.
• Specify package condition, moisture-sensitivity handling, packing and labeling requirements.
• Request lot/date-code information and traceability documentation appropriate to the transaction.
• Use incoming inspection, programming verification or functional testing proportionate to application risk.
• Avoid approving substitutes solely on price; conduct engineering and quality review first.
Frequently Asked Questions
