The PIC16F15375 moves up to a 40- or 44-pin package while retaining the Enhanced Mid-Range 8-bit core, 14 KB of flash, 1 KB of SRAM and the same Core Independent Peripherals as its 28-pin relatives. More pins bring more I/O and a 35-channel ADC, which makes the part a favourite in control panels and sensor-rich hubs. When that code is locked, our dump encrypted PIC16F15375 memory service recovers the application so the hardware can be serviced or cloned.

S3P9228 Microprocessor Flash Program Cloning

Why designers lock this part

Engineers enable code protection to stop a competitor pulling the firmware off a shipped board. On the PIC16F15375 the protect bits live in the configuration words and, once set, block external reads of the flash. Microchip’s documentation is blunt that clearing them is a bulk-erase event, which would wipe the very program the owner needs. A proper dump encrypted PIC16F15375 memory engagement reads the array without triggering that erase and keeps the confirmed-good firmware.

Characterising the protection state

We begin by confirming the package and powering the device within its 1.8 to 5.5 V range. Through ICSP we read the configuration space to learn exactly which protect levels are active. This step is what separates a recovery from a gamble: with the state known, the read sequence is chosen to preserve the data rather than destroy it, exactly as we do for the unlock protected PIC16F15356 microcontroller work, and as the copy protected PIC16F15386 binary job does at the top of the memory range.

Extracting and verifying the image

The 14 KB flash is captured in a controlled pass, the configuration words are recorded, and a checksum confirms the binary matches the silicon. The larger pin count changes only the board handling, not the recovery logic. For context on the legal and technical framing, the reverse engineering MCU memory originality discussion is a useful companion, and the practical side is covered by our MCU flash EEPROM data cloning capability that spans the whole Enhanced Mid-Range line.

From dump to clone

With a verified image we can reproduce the part or deliver the hex and binary for your records. When a product is only partly locked, our partial microcontroller chip cloning reference describes how a partial recovery is bounded and documented. The extract microcontroller PIC16F1509T flash memory firmware guide shows how the family behaves during a read.

Working with the 35-channel ADC data

The 35-channel analogue front-end is usually the reason this footprint was chosen, and the calibration constants that make those readings accurate often live inside the flash. A recovered image therefore preserves not just the program but the tuning that turns raw counts into real volts and amps. When we rebuild a clone we keep that data intact, so the replaced device measures the same way the original did. That continuity is what lets a recovered board re-enter service without a full recalibration pass on the bench, and it is why a non-destructive read is worth doing properly rather than approximating the constants.

Where the 40/44-pin part is used

Control panels, HVAC controllers, industrial I/O and multi-sensor nodes make heavy use of the extra pins and the 35-channel ADC. Those are long-life products that frequently outlive their source code, which is why recovery requests for this footprint are common and why we keep a matching archive format ready for the MCU flash EEPROM data cloning step that follows.

Pin mapping fidelity across forty pins

A 40-pin device spreads CCP outputs, ADC inputs and comms pins around the full perimeter, and the mapping is chosen by the designer rather than fixed by the family. Our recovery therefore records the configuration words that steer those peripherals onto their assigned pins, so the cloned part drives the right motor phase or samples the right channel from the first power-up. Boards rarely label these choices, which makes a faithful capture far cheaper than tracing every net by hand.

Authorisation and handling

We process only devices you own or are entitled to service, and we keep documentation of that right. Every unit leaves with a verification report, and we never publish anything that would help improper copying of hardware you do not control.

Getting started

Mail us the locked PIC16F15375 or the board it sits on, and we will confirm the package, quote a fixed recovery fee, and return the firmware with proof of integrity. The recovered image can then be replicated on demand using the same cloning pipeline we run for every supported Microchip part.
