The LPC1810FBD144 is an NXP LPC18xx part: a Cortex-M3 at 180 MHz with no on-chip flash and 200 KB of SRAM in a LQFP144. Our recovery desk handles the LQFP144 capture and returns a verified image.
Bench Routine
We read no on-chip flash (or the SPIFI device on flashless parts), the OTP and signature area, then a live RAM image, then re-check. The capture order on the LPC1810FBD144 is on-die flash or SPIFI image first, then the OTP region, then any live RAM, then a second pass.
Flash And Working Memory
The LPC1810FBD144 maps no on-chip flash for execution and 200 KB of SRAM for data, with an EMC that can attach off-die SDRAM. Because the LPC1810FBD144 includes an external-memory controller, a board may place code or data in off-chip SDRAM through the EMC. The RX24T hex note documents a 64-pin cousin with the same debug-ID convention.
Where The Read Protection Lives
The LPC1810FBD144 guards its array with a code-read-protection bit in the code flash signature and OTP area, a reversible setting. NXP’s CRP on the LPC1810FBD144 is a bit in the code flash signature region that blocks debugger reads but never erases the array. A bypass methodology covers the non-destructive approach for a LPC1810FBD144 in detail.
Reporting And Hand-Off
Delivery is one Intel HEX at the true addresses, a binary per region, and a report listing the CRP state and boot source. Customers get an Intel HEX merging all regions at real addresses, separate binaries, and a short report for the LPC1810FBD144 LQFP144. The LPC1812JET100 note is the matching entry for another member of the LPC1810FBD144 line.
Peripheral Set
The LPC18xx character of the LPC1810FBD144 comes from the HSADC near 80 Msps and the SCT state-configurable timer built in hardware. What makes a LPC1810FBD144 more than a generic Cortex-M3 is the HSADC and the SCT, both configured by code in no on-chip flash. The LPC2378 MiniBus note is a contrast where external bus carried part of the image.
For a 144-pin LPC1810FBD144 the alternate-function pins are decoded from the dump, not guessed from the silk.
We keep the capture bench notes with the order so the LPC1810FBD144 protection level is never lost between reads.
Where a live LQFP144 board is supplied we trace the serial lines before removing power from the LPC1810FBD144.
We note the batch code on the LQFP144 LPC1810FBD144, which sometimes explains a quirk in the silicon revision.
Where a bootloader stage exists that region is captured in full for the LPC1810FBD144, the usual third-party omission.
We separate the no on-chip flash from working memory in the archive, since mixing them hides the code lock state.
Where decapsulation was needed the bare die of the LPC1810FBD144 is photographed before the lid is fully removed.
The 144-pin LPC1810FBD144 is logged against its order code so a repeat job reuses the same bench setup.
Our report flags any external memory the LQFP144 board carried, since the LPC1810FBD144 image may span parts.
The delivery keeps the original protection state of the LPC1810FBD144, so a later comparison reuses the same settings.
A 144-pin LPC1810FBD144 that failed a previous shop usually still yields to a careful second pass.
We store the LQFP144 board in anti-static foam until the read is done and the files are handed over.
The Cortex-M3 at 180 megahertz on the LPC1810FBD144 runs the recovered code in place, so the report notes the boot setup for a spare LQFP144.
We keep the original oscillator value in the report, since a wrong crystal stops a rebuilt 144-pin board.
The customer gets a plain summary with the LPC1810FBD144 files, written for a non-engineer to follow.
The no on-chip flash on the LPC1810FBD144 is read at the true addresses, not a relocated image a tool might invent.
The customer receives the files with a short note on reflashing the LQFP144 without tripping the code lock again.
A second confirming read is offered when a customer wants proof no weak cell moved on the LPC1810FBD144 LQFP144.
For the LQFP144 LPC1810FBD144 we confirm the pin one mapping against the data sheet before closing the job.
The LQFP144 outline of the LPC1810FBD144 matches other group members, so the marking confirms the exact die fitted.
Our turnaround notes record the socket used, because the LQFP144 LPC1810FBD144 rarely sits in a standard adapter.
