The PIC16F18324 is the 7 KB step of the PIC16F183 family on a 14-pin package, with 512 bytes of SRAM, a 256-byte data EEPROM and a richer peripheral set that adds four Configurable Logic Cells and a Data Signal Modulator. When that code is locked, our unlock protected PIC16F18324 chip service recovers the firmware from hardware you own without erasing the original.

Protection on the 7 KB device

Security sits in the configuration words, exactly as on the other PIC16F183 parts. Enabling code protection blocks external reads of the flash, and Microchip’s guidance is that clearing it requires a bulk erase. A careful unlock protected PIC16F18324 chip recovery reads the array while the data remains, avoiding that destructive path and keeping the confirmed-good firmware intact through the whole operation.

Reading with the right sequence

After confirming the 14-pin package and powering within 1.8 to 5.5 V, we use ICSP to learn the exact protect state before any read. We take the 7 KB program space, the EEPROM block and the config words in a single non-destructive read, then bind them with a checksum. The same approach protects the crack secured PIC16F18323 source code work at the 3.5 KB tier, and the decrypt encrypted PIC16F18326 software recovery at the 28 KB top end, because the read order is what prevents data loss.

Peripheral-aware extraction

Because the PIC16F18324 adds more CLC and DSM resources, we note their configuration where it affects reconstruction of the application. For related family behaviour, our extract microcontroller PIC16F1509T flash memory firmware reference describes how these blocks behave during a read, and the microcontroller internal storage structure analysis explains the memory map we work against when planning the capture.

Reconstructing the CLC and DSM logic

The four Configurable Logic Cells and the Data Signal Modulator are what make the PIC16F18324 interesting, and they are configured through special function registers that sit alongside the program. When we recover the part we capture those registers as part of the image, so the custom combinational and modulated outputs the designer built in silicon are preserved in the clone. Missing that step is a common reason amateur copies misbehave: the code runs but the glue logic between peripherals is wrong. By treating the CLC and DSM setup as data to be recovered rather than ignored, we return a device whose behaviour matches the original across the whole chip, not just in the flash array.

Proving the clone by behaviour, not bytes alone

A checksum proves the image matches the silicon, but the strongest assurance is watching the recovered firmware run. For the PIC16F18324 we often mount a freshly programmed part on a simple bench fixture so the CLC outputs, the DSM modulated signal and the EEPROM-backed settings can be exercised exactly as the original board drove them. Comparing those outputs against the donor device confirms that the glue logic and the program behave as one, which is the standard a replacement part has to meet. Where a customer supplies the end-product board, we run the same comparison in circuit, checking that the clone starts, communicates and shuts down like the original. Only after that behavioural pass does the recovery report get signed off, so what reaches you is a part we have seen working rather than a file we merely believe is complete.

Applications of the mid-memory part

The 7 KB device suits brushless motor control, LED drivers and analogue front-ends where the extra CLC and DSM blocks earn their place. Those designs are locked for IP reasons and later need recovery when the design house has moved on, so a verified image is the fastest route back to production.

Framing the work

The unlock microcontroller embedded memory guide explains the principles we follow. We apply them only to devices you own or are entitled to service, and we keep a record of that entitlement for every job, then duplicate through our MCU flash EEPROM data cloning service once the verification report is complete.

Contact

Send the locked PIC16F18324 and we will confirm the package, quote a fixed fee, and return the hex file with integrity proof. The recovered image can then be cloned into new components through the same pipeline we run across the PIC16F183 line.
