PIC16F17146 Product Overview

The PIC16F17146 is a full-featured 20-pin 8-bit microcontroller designed for applications that need compact control together with advanced analog capability. It combines 28 KB of program Flash, 2 KB of SRAM, data EEPROM and a broad set of analog and digital peripherals.

Its 12-bit Analog-to-Digital Converter with Computation (ADCC), on-chip operational amplifier, comparators and DAC resources can simplify sensor front ends and feedback-control circuits. Core Independent Peripherals help execute timing and waveform functions with reduced CPU intervention.

This page targets engineers and buyers searching for PIC16F17146 specifications, analog features, package information and sourcing support. Confirm all electrical limits and peripheral details against current Microchip documentation.

PIC16F17146 Key Specifications

Specifications can vary by package, device revision and full ordering code. Engineers should validate pinout, electrical limits, programming requirements and errata against the latest Microchip documentation before releasing a design.

Why This Device Attracts Buyer and Engineer Interest

Integrated sensor-signal chain

The 12-bit ADCC and op amp make the device relevant to current, voltage, pressure, temperature and other conditioned-sensor applications.

Compact mixed-signal control

A 20-pin MCU with 28 KB Flash and broad analog resources can reduce board area and external analog components in moderate-complexity control products.

Safety-oriented design support

Microchip identifies Functional Safety Support for the family. This does not certify an end product, but it can support customers building documented safety processes.

Typical Applications

Smart sensors and transmitters

Use the analog signal chain, computation-assisted ADC and serial interfaces for local measurement and data conditioning.

Power and motor-control auxiliaries

Suitable for monitoring, fault handling, waveform generation and supervisory control around a primary power stage.

Industrial actuators and controllers

The combination of analog peripherals and configurable logic supports compact closed-loop modules.

Appliance and automotive auxiliary electronics

Functional-safety and automotive positioning can be relevant to qualified control and monitoring functions, subject to exact device grade.

Design and Procurement Advantages

• On-chip op amp and 12-bit ADCC reduce external analog-front-end burden.

• 28 KB Flash and 2 KB SRAM provide useful headroom in a 20-pin class.

• Two EUSARTs and two I2C/SPI modules support multi-interface products.

• Focus and Functional Safety Support positioning creates a strong new-design narrative.

Package and Ordering-Code Guidance

The base name PIC16F17146 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 showed PIC16F17146 as In Production and as a Focus product on the review date. It is suitable for active design-in promotion, while the exact automotive, industrial and package variants must be checked before quotation.

Alternative and Migration Options

• PIC16F17126 for a smaller related device when fewer I/O resources are sufficient.

• PIC16F17156 or PIC16F17176 when a higher pin count is required.

• PIC16F18146 when the on-chip op amp is not required but similar memory and control resources are useful.

• PIC16F18446 for another compact 20-pin option with rich control and communication peripherals.

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

Why is PIC16F17146 suited to sensor applications?

It integrates a 12-bit computation-assisted ADC, an op amp, comparators, DAC resources and serial interfaces in a compact device.

Does Functional Safety Support certify my product?

No. It indicates manufacturer support resources; the end-product safety case, architecture, validation and certification remain the customer’s responsibility.

Is PIC16F17146 in production?

Yes. Microchip displayed it as In Production on 14 September 2026.

What should a sourcing request include?

Use the full order code and specify package, temperature grade, quantity, annual demand, delivery country and documentation requirements.
