PIC16F1829 Product Overview
The PIC16F1829 is a 20-pin enhanced mid-range microcontroller with 14 KB Flash, 1 KB RAM, EEPROM, analog inputs and common serial interfaces. It provides more memory and performance than many small 8-bit devices while retaining a compact package.
Its XLP low-power features and mixed-signal resources make it relevant to battery-powered instruments, sensor nodes and distributed control boards. The device is also useful when an existing PIC16 architecture must be retained but a smaller package is preferred.
For SEO and sales conversion, the page should emphasize the 20-pin form factor, memory capacity, 32 MHz operation and low-power application fit.
Market position Best content angle: compact 20-pin controller with strong memory for an 8-bit device. Useful for low-power and communication-enabled products, with both new-design and installed-base demand. |

Why This Device Still Attracts Buyer and Engineer Interest
Memory in a compact package
Fourteen kilobytes of Flash and one kilobyte of RAM provide useful headroom for a 20-pin 8-bit control application.
Low-power operation
XLP features support products that spend significant time in sleep or must run from limited energy sources.
Integrated communications
EUSART and SPI/I2C resources make the device suitable for sensor interfaces and local communication nodes.
Typical Applications
Portable measurement products
ADC, EEPROM and low-power operation support battery-powered instruments and data collection.
Smart sensors
The MCU can acquire analog inputs, apply local control logic and communicate with a host.
Appliance and consumer controllers
Timers, PWM, EEPROM and serial interfaces support compact feature-rich control boards.
Distributed industrial nodes
The 20-pin package can fit compact boards that need analog I/O and serial communication.
Design and Procurement Advantages
• Strong Flash and RAM capacity for a 20-pin 8-bit MCU.
• EEPROM for calibration values and persistent settings.
• XLP features for energy-sensitive products.
• Multiple serial and analog peripherals in compact packages.
Package and Ordering-Code Guidance
The part is offered in through-hole and surface-mount 20-pin packages. Verify the exact I/O and peripheral mapping for the selected package, and distinguish PIC16F and PIC16LF variants by voltage requirements.
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 PIC16F1829 as In Production on the review date. It is a mature enhanced-mid-range product with useful compact-control positioning.
Alternative and Migration Options
Compare potential replacements based on pin count, EEPROM, RAM, low-power current, communication modules and Peripheral Pin Select requirements.
• PIC16F18855 for more advanced core-independent peripherals in a 28-pin device.
• PIC16F15244 for a current cost-effective 20-pin option with a different memory/peripheral profile.
• PIC16F690 for older 20-pin installed-base requirements with lower memory.
• Small 32-bit MCUs where software complexity or computation requires a broader architecture.
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.
