PIC16F886 Product Overview
The PIC16F886 is a 28-pin enhanced mid-range 8-bit MCU related to the PIC16F887 family. It provides 14 KB Flash, EEPROM, analog inputs, communications and control peripherals for embedded products that need fewer pins than a 40-pin device.
The model remains relevant in industrial, appliance and instrumentation designs where the hardware and firmware are already qualified. Its smaller pin count can also suit cost-sensitive boards that do not need the additional I/O of PIC16F887.
This landing page should serve both technical-selection searches and exact-model sourcing inquiries, while making clear that any migration requires full pin and firmware validation.
Market position Best content angle: 28-pin member of the established PIC16F88x family. Demand is likely more exact-model and maintenance focused than broad new-design search traffic. |

Why This Device Still Attracts Buyer and Engineer Interest
28-pin form factor
It offers useful memory and peripheral capability without the board area of the 40/44-pin family member.
Persistent parameter storage
On-chip EEPROM supports calibration, configuration and user settings.
Family familiarity
Teams that already maintain PIC16F88x firmware and tools can reduce development disruption.
Typical Applications
Industrial control boards
Discrete I/O, analog inputs and serial communication support compact controllers.
Appliance electronics
The MCU can coordinate sensors, user inputs, relays and indicators.
Instrumentation
ADC and EEPROM resources support measurement and stored calibration data.
Maintenance and redesign-minimization
Exact replacement can preserve validated PCB and firmware configurations.
Design and Procurement Advantages
• 14 KB Flash and EEPROM in a compact 28-pin family.
• Analog, communications and timer resources for general embedded control.
• Mature architecture and widely understood development workflow.
• Useful bridge between small 20-pin devices and 40-pin PIC16F887.
Package and Ordering-Code Guidance
Confirm the complete suffix because package, temperature grade and packing differ. Surface-mount package dimensions and pin mapping must be matched to the existing PCB; “PIC16F886” alone is not a complete procurement specification.
1. Quote the complete orderable part number, not only the base device name.
2. Confirm package, temperature grade, packing method and required compliance documentation.
3. For replacement or migration projects, verify pin compatibility, oscillator behavior, peripheral registers, programming voltage and firmware changes.
4. For production purchases, agree acceptable lot/date-code range and traceability requirements before order confirmation.
Lifecycle and Market Position
Microchip displayed PIC16F886 as In Production on the review date. Treat it as an active mature component whose strongest value is compatibility with established designs.
Alternative and Migration Options
Potential alternatives depend on whether the goal is more I/O, newer peripherals, lower power or exact PCB compatibility.
• PIC16F887 for more I/O in a 40/44-pin family member.
• PIC16F1829 for a 20-pin enhanced-mid-range architecture with more RAM.
• PIC16F18855 for newer peripheral capabilities in a 28-pin device.
• Exact PIC16F886 sourcing when qualification cost outweighs migration benefits.
Alternative devices are comparison starting points only. They are not automatically pin-compatible or firmware-compatible, and the final choice must be validated against the complete electrical, mechanical and regulatory requirements.
Sourcing and Quality Checklist
• Confirm manufacturer, complete ordering code and requested quantity.
• Review product status, current PCNs, errata and any 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 and functional or programming verification proportionate to the application risk.
• Avoid approving substitutes solely on price; conduct engineering and quality review first.
Frequently Asked Questions
What is the main difference between PIC16F886 and PIC16F887?
PIC16F886 is the lower-pin-count device, while PIC16F887 offers more I/O in 40/44-pin packages. Review the full datasheet for peripheral and pin differences.
Does PIC16F886 include EEPROM?
Yes, it provides 256 bytes of data EEPROM.
Is PIC16F886 still active?
The official product page displayed In Production on 31 August 2026.
Can another PIC16F88x device be substituted without firmware changes?
Not necessarily. Configuration bits, pin mapping, peripheral implementation and memory differences must be checked.
