PIC16F19155 Product Overview

PIC16F19155 is a 28-pin lcd-controller class member of the PIC16F191 8-bit microcontroller family. It combines 14 KB of program Flash, 1,024 bytes of SRAM and package-dependent I/O resources with 12-bit adc with computation and intelligent analog. Compact LCD and touch-control MCU for battery-powered interfaces. The PIC16F191 family combines an LCD controller, touch-sensing support, intelligent analog and XLP features for battery-powered displays and human-machine interfaces. It provides a differentiated 8-bit option where a dedicated segment LCD and real-time control must coexist in one MCU.

For independent-distribution and sourcing content, the most credible positioning is not to describe PIC16F19155 as universally “best” or “hot.” Instead, the landing page should connect its memory, pin count and peripherals to a defined design problem, while clearly separating technical suitability from live inventory and pricing.

Key Technical Specifications

Why This Device Is Worth Promoting

Targeted SEO for meters, thermostats, white goods, handheld instruments, battery-powered LCD products and panel interfaces. These pages have narrower traffic than general-purpose MCUs but can attract higher-intent engineering and maintenance inquiries.

· Model-specific search intent: buyers often search “PIC16F19155 datasheet,” “PIC16F19155 supplier,” “PIC16F19155 price” or an exact ordering code.

· Clear application angle: Compact LCD and touch-control MCU for battery-powered interfaces.

· Scalable family story: adjacent PIC16F191 devices can be linked for memory, package and I/O migration.

· Commercial conversion opportunity: the page can capture both engineering qualification and purchasing/RFQ traffic without publishing unverified stock claims.

Typical Applications

· battery-powered meters

· thermostats

· white-goods displays

· handheld LCD instruments

PIC16F19155 should be presented as a candidate for these applications, not as an automatic drop-in solution. Final suitability depends on firmware size, timing, analog accuracy, package, temperature range, qualification requirements and the complete system architecture.

Selection and Design Considerations

Choose between memory density and package/pin count. The 28-pin variants suit compact displays, while 64-pin variants support high segment counts and broad I/O requirements.

1. Confirm that the Flash and SRAM margin covers production firmware, bootloader, communication stacks and future updates.

2. Check the exact peripheral instances, PPS mapping, ADC channels, timers and communication requirements against the current datasheet.

3. Select the complete orderable part number, including package, temperature grade and packing format; the base model alone is not sufficient for a purchase order.

4. Review the latest silicon errata, PCNs and lifecycle information before design release or approving an alternative.

5. Do not describe a related part as pin-compatible or firmware-compatible unless the pinout, electrical limits and software migration have been verified.

Adjacent Devices and Migration Direction

· Higher-memory direction: PIC16F19156

· Alternative I/O or package direction: PIC16F19195

LCD segment capacity, touch channels, package, I/O and supply range depend on the exact device and orderable suffix. Confirm the final display topology and current datasheet before design-in.

Procurement and Quality Checklist

· Request the full manufacturer part number and target quantity, not only the base device name.

· Confirm package, lead count, temperature grade, RoHS/REACH requirements and tray/tube/tape packaging.

· Verify date code expectations, traceability documents, moisture sensitivity level and storage condition when required.

· For legacy maintenance, confirm firmware and board revision before proposing an alternative.

· For new designs, compare current family members and current Microchip recommendations rather than choosing only by spot price.

Frequently Asked Questions

What is PIC16F19155 mainly used for?

It is best positioned for battery-powered meters, thermostats, white-goods displays. The exact fit depends on memory, I/O, analog and communication requirements.

Is PIC16F19155 suitable for a new design?

Potentially. Official product page lists the device In Production, Focus and recommended for specified automotive designs; verify exact ordering code. Check the current product page, datasheet, errata and availability before final design-in.

Can another PIC16F191 device replace PIC16F19155?

A related family member may provide a memory or I/O migration path, but pin compatibility, peripheral mapping, electrical characteristics and firmware must be reviewed.

What information is needed for an RFQ?

Provide the full orderable part number, quantity, target date code, packaging, delivery destination and any traceability or inspection requirements.
