The PIC16F15245 tops the 20-pin tier of the 152xx family: 14 KB of flash, 1024 bytes of SRAM and eighteen I/O lines, with the same 32 MHz enhanced mid-range core and memory access partition as its siblings. Fourteen kilobytes accommodates a bootloader plus a real application, so this package often carries both in a carefully provisioned layout. When protection is engaged, our unlock protected PIC16F15245 flash service recovers the full image from hardware you own.

Reading a provisioned part correctly

Provisioning is where this generation differs from older PIC16 parts. Code protection can close the application block while the boot block stays writable for updates, and the storage area flash block can be locked or open independently. The configuration words therefore read like a policy document: they tell you what the manufacturer intended to protect. An unlock protected PIC16F15245 flash job interprets that policy, reads every recoverable region in place, and treats the bulk erase as the one path that must never run, because it destroys the very image the owner needs.

Boot plus application in one capture

Recovering both regions in a single consistent pass matters more here than on smaller parts, because a bootloader and its application share assumptions about vector placement and update framing that only make sense together. We capture the three blocks in one session, checksum each, and verify that the boot block’s accepted-command set still matches what the application expects – a check that has caught provisioned parts whose storage area was reflashed with parameters from a different variant. The report lists each block separately so your team can re-issue updates through the boot block without re-programming the application. Handling discipline for partitioned arrays is set out in the how the MCU memory works guide, and duplication runs through the MCU flash EEPROM data cloning pipeline with read-back proof on every part.

Vectors, framing and cross-block assumptions

A bootloader and its application agree on things neither documents explicitly: where the reset vector lands, how update records are framed, which storage-area checksum scheme both sides trust. Recovery work on this part therefore includes an explicit reconciliation pass – we read the boot block’s verification routine and the application’s update writer, and confirm the assumptions match on both sides. Mismatched donors are rare but real, usually the residue of a factory rework or a partial field campaign, and they produce images that flash correctly and never update again. The reconciliation result goes into the report as a short table, so your team knows the update path has been exercised rather than assumed.

Re-issuing updates without re-programming

Because the boot block survives application updates, a properly recovered image lets the owner keep the manufacturer’s own update channel alive. We verify that channel end to end on the bench: a blank clone is programmed, booted, and taken through one full update cycle using the boot block’s own protocol before delivery. The exercise proves the framing table, the erase boundaries and the final-jump logic in one pass, and it leaves the customer with a documented, repeatable update procedure instead of a chip they are afraid to touch. Fleets that inherited this capability from our deliveries have retired their programming fixtures entirely – updates now ride the original channel the factory built.

Why auditors ask for block-level checksums

For customers in regulated industries, the recovery is only half the deliverable – the other half is evidence that the recovery did what it claims. Block-level checksums, read twice and recorded, let an auditor confirm the image corresponds to the donor without re-running the job. Our reports are formatted so those checks can be recomputed with ordinary tools, no special software required. Quality departments told us the format shaved hours off their validation reviews, and the same structure now ships with every job on this family, not just the regulated ones.

Family and scope

The 7 KB sibling is on the PIC16F15244 microcontroller page, the 28-pin flagship on the PIC16F15255 firmware recovery, and bounded-scope work on the partial microcontroller chip cloning reference. The lawful boundary for all of it is framed in the reverse engineering integrated circuit legitimate foundation article.
