The PIC16F15223 brings the 152xx architecture into a 14-pin package: 3.5 KB of flash, 256 bytes of SRAM, twelve I/O lines with peripheral pin selection and a 9-plus-2 channel 10-bit ADC with SMBus-compatible pads. It is the volume sensor-controller of the family, and when its code protection bits are set, the program is invisible to every external programmer. Our copy encrypted PIC16F15223 program service recovers the image from hardware you own.

Protection layout before any read

This generation’s memory access partition splits flash into application, boot and storage area blocks with independent protection, so the working assumption that one bit guards everything no longer holds. Some units we receive have only the application block closed, leaving parameter storage readable; others are fully locked. The copy encrypted PIC16F15223 program procedure starts by probing that layout through the configuration words, then reads each region in place without triggering the bulk erase that clearing protection would require.

Analogue behaviour worth preserving

Twelve I/O pins and a nine-external-channel ADC make this part a front-end as much as a controller, and analogue front ends carry calibration. Gain and offset behaviour depends on constants that may sit in the storage area block or be computed at boot, and a clone without them measures like the original only by luck. Our capture therefore includes every block, and verification exercises the ADC against the donor’s signature on a bench fixture rather than trusting checksums alone. The delivered report notes which regions held structured data, which saves your team a reverse-engineering pass. Bench discipline for this class of part is described in the microcontroller firmware instruction reference, and the lawful framing of the work in the semiconductor chip hardware security overview.

Channel-by-channel ADC mapping

Nine external channels plus two internal references give this part enough analogue width for multi-sensor boards, and the channel assignment is decided entirely in software through the pin selection and ADC control registers. Recovered images therefore carry a channel map that exists nowhere on the schematic, and our report reconstructs it: which pin was scanned in which order, at what sampling interval, and which internal channels fed the offset corrections. Where the scan order interacts with settling time – as it does on high-impedance sensors – we verify the sequence on the bench with signals on two channels simultaneously, because a clone that scans in the wrong order produces plausible-looking but subtly wrong readings that only show up against a reference instrument.

Front-end verification cases

The sensor products built on this part typically compare the clone and donor conversions directly before we release the image. In one batch of temperature-loggers, the donor’s readings tracked a calibrated reference within a tenth of a degree while the first clone attempt drifted by two – traced to a single constant that scaled the internal reference channel. The comparison fixture found it in minutes, and the corrected clone matched the donor across the full range. That is the standard we apply to every analogue-bearing image: bytes equal is necessary, but measurements equal is the delivery criterion.

The internal reference channel

Two of the ADC’s eleven inputs are internal – the fixed voltage reference and a temperature-indicator path – and both are calibrated at the factory with values stored in the device information area. Recovery keeps that area with the image, because the application’s conversions are computed against those stored constants. A clone that drops the information area converts perfectly by its own lights and wrong by the instrument’s, which is the discrepancy our parallel measurement step exists to catch. The report includes the reference values as read, so your engineers can sanity-check any future retuning against what the factory measured.

Duplication

Verified images are programmed into matching 14-pin blanks with configuration words restored and read-back comparison on every unit, through the MCU flash EEPROM data cloning pipeline. The 7 KB sibling is covered on the PIC16F15224 code page, and the 20-pin member of the same datasheet on the PIC16F15243 software recovery.
