PIC16F13145 Product Overview

The PIC16F13145 is a 20-pin enhanced mid-range 8-bit microcontroller from Microchip Technology. Its key differentiator is an integrated Configurable Logic Block (CLB), which can implement custom combinational and sequential logic inside the MCU.

For engineering teams, the CLB can offload timing-sensitive logic, simple state machines, protocol adaptation and signal conditioning from firmware. In suitable designs, it may also reduce external logic devices, PCB area and bill-of-material complexity.

This page is intended for users researching PIC16F13145 specifications, CLB applications, package options and sourcing support. Final design and purchasing decisions must use the latest official datasheet, errata and complete orderable part number.

PIC16F13145 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

Hardware logic without a separate programmable device

The CLB is the main commercial story. It gives designers a way to implement custom logic functions inside a low-cost MCU and can reduce dependence on discrete gates or a small CPLD in appropriate applications.

Deterministic peripheral interaction

Hardware-based logic can react independently of the CPU instruction flow, which is useful for signal gating, sequencing, event qualification and low-latency control functions.

Strong new-design content potential

Microchip marks the device as a Focus product. That makes the page suitable for application-led content, samples, evaluation support and design-in inquiries rather than only replacement demand.

Typical Applications

Industrial control and sequencing

Custom state logic, interlocks, pulse qualification and peripheral coordination can be implemented with less firmware timing burden.

Power and energy control

Useful for sequencing, fault gating, signal generation and supervisory functions in compact power-control designs.

Sensor and interface products

The ADC, serial interfaces and logic resources suit smart sensors, interface modules and protocol-adaptation functions.

Consumer and appliance control

A compact package and integrated logic can simplify control boards where cost, space and deterministic behavior matter.

Design and Procurement Advantages

• Configurable hardware logic is a clear differentiator from conventional small 8-bit MCUs.

• Integrated ADC, serial interfaces and logic resources can reduce external components.

• 20-pin positioning suits compact controller and interface boards.

• Manufacturer Focus positioning supports new-design and application-content campaigns.

Package and Ordering-Code Guidance

The base name PIC16F13145 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 PIC16F13145 as In Production and identified it as a Focus product on the review date. This supports active promotion, but availability, lead time and package coverage still need confirmation for the exact orderable suffix.

Alternative and Migration Options

• PIC16F13144 or PIC16F13125 when a related device with different memory or pin requirements is appropriate.

• PIC16F17146 when advanced analog integration, including an on-chip op amp, is more important than a CLB.

• PIC16F18146 when a compact full-featured control MCU with 12-bit ADC capability is preferred.

• A small CPLD plus MCU architecture when logic complexity exceeds the CLB resources.

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

What makes PIC16F13145 different from a conventional PIC16 MCU?

Its key differentiator is the Configurable Logic Block, which supports custom hardware logic functions inside the MCU.

Can the CLB replace all external logic devices?

No. It can replace selected low-complexity logic in suitable designs, but engineers must validate logic capacity, timing, I/O and safety requirements.

Is PIC16F13145 in production?

Yes. Microchip displayed the base device as In Production on 14 September 2026. Exact suffix availability must still be confirmed.

What information is required for a quotation?

Provide the complete orderable code, package, temperature grade, quantity, annual demand, target delivery date and traceability requirements.
