The PIC16F1778 tops the 28-pin tier of the 177x family: 28 KB of flash, 2048 bytes of SRAM and twenty-five I/O lines around an analogue array built in threes – three op amps and six comparators feeding a seventeen-channel 10-bit ADC, three DACs at each resolution, and a matching set of ramp generators behind three complementary output generators. Twenty-eight kilobytes on a mid-range core hosts a complete power product: control loops, a communication protocol, a boot flow and a parameter store. When protection is engaged, our crack locked PIC16F1778 source code service recovers it from hardware you own.

Reading a 28 KB image with structure

An image this size rewards structured handling: vector placement, the boot flow’s accepted-command set, the communication protocol’s framing and the analogue constants each occupy identifiable regions, and a capture that flattens them loses information the owner will need later. Our crack locked PIC16F1778 source code delivery therefore includes a region map – which sectors hold the boot flow, where parameter tables sit, which constants drive the analogue interconnect – alongside the raw image and its per-sector checksums. The verification fixture runs the clone and donor through communication sessions and load transients in parallel before anything ships. Protection is the family’s configuration-word scheme: engaged, it refuses every external read; clearing it means the bulk erase that destroys the array, so that sequence never runs. The 128-byte high-endurance flash block is captured with the rest, since products of this complexity commonly keep cycle counters or identity data there. Bench discipline is in the how the MCU memory works guide, and the commercial boundary in the semiconductor chip hardware security overview.

Anatomy of a 28 KB image is worth summarising for the teams who inherit our captures. In the supplies and chargers we typically see, the first sectors hold the vector table and boot acceptance logic, the middle block the control-loop and protocol code, and the upper region parameter tables plus a small logging area; the high-endurance block rides outside all of it. That anatomy drives the capture order as well as the report: sectors are checksummed individually precisely so a later partial re-read can be reconciled without re-capturing everything. Customers using the image for re-design receive the region map in machine-readable form alongside the annotated version.

Communication-session verification on this part runs both directions. The fixture plays recorded donor sessions to the clone and records the clone’s responses, then plays the clone’s traffic back against the donor – asymmetries in either direction indicate framing or timing constants that differ from the original. Supplies and chargers talk to host systems that were rarely documented by the original vendor, so the transcripts we deliver are frequently the first complete record of the product’s protocol that the owner has ever held, and they double as regression fixtures for future firmware work.

Duplication

Duplication runs on our MCU flash EEPROM data cloning line: each 28-pin blank is programmed with the image plus its configuration words and high-endurance block, then read back and compared before it leaves the bench, and bounded-scope work follows the partial microcontroller chip cloning framework.

Protocol documentation is often the most durable part of a recovery’s value. Long after the replacement parts are programmed, the transcripts and framing notes from our communication verification keep serving as the product’s interface specification – for host-software updates, second-source tooling or audit questions. We format those notes so they can be handed to a software team without a hardware background, which is a small extra step that customers tell us outlives the original recovery many times over.

Family links

The 40/44-pin members are on the PIC16F1777 chip page, the 28-pin 7 KB and 14 KB siblings on the PIC16F1773 binary and PIC16F1776 MCU recoveries, and the 171x 28-pin 28 KB predecessor on the PIC16F1718 firmware page.

Region maps from this family have also proven useful during failure analysis: when a returned unit misbehaves, knowing which sectors hold parameters versus code lets a diagnostician focus probes quickly instead of disassembling blind. The map travels with the image in both annotated and machine-readable form for exactly that reason.

Scope and next step

Every engagement starts with proof of ownership or authorisation, recorded with the work order. Send the locked PIC16F1778 – or the board it controls – and we will confirm the package and fee, then return the recovered source with its region map and per-sector integrity proof.
