The LPC1813JBD144 is an NXP LPC18xx part: a Cortex-M3 at 180 MHz with 512 KB of flash and 104 KB runtime memory in a LQFP144. The recovery service reads the LPC1813JBD144 physically and preserves its protection state.
Flash And Working Memory
The LPC1813JBD144 maps 512 KB of flash for execution and 104 KB runtime memory for data, with an EMC that can attach off-die SDRAM. Because the LPC1813JBD144 includes an external-memory controller, a board may place code or data in off-chip SDRAM through the EMC. The RX563 extraction case shows a larger RX part with the same debug-ID convention.
Where The Read Protection Lives
The LPC1813JBD144 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 LPC1813JBD144 is a bit in the code flash signature region that blocks debugger reads but never erases the array. A bypass overview explains holding a steady rail and reading twice on 5 V silicon.
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 LPC1813JBD144 LQFP144. A sibling page on the related LPC1815JET100 covers the same group from a different package angle.
Peripheral Set
The LPC18xx character of the LPC1813JBD144 comes from the HSADC near 80 Msps and the SCT state-configurable timer built in hardware. What makes a LPC1813JBD144 more than a generic Cortex-M3 is the HSADC and the SCT, both configured by code in 512 KB of flash. A PIC clone note shows the timing source is reconstructed from evidence, not the hex alone.
Bench Routine
We read 512 KB of 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 LPC1813JBD144 is on-die flash or SPIFI image first, then the OTP region, then any live RAM, then a second pass.
A LQFP144 LPC1813JBD144 that locked mid-project is common; the code array is intact, only the debug path is closed.
The Cortex-M3 clocked at 180 MHz clock source is noted for the LPC1813JBD144, because a clone with the wrong PLL will not start.
For the LQFP144 LPC1813JBD144 we confirm the pin one mapping against the data sheet before closing the job.
A second confirming read is offered when a customer wants proof no weak cell moved on the LPC1813JBD144 LQFP144.
A recovered LPC1813JBD144 is cross-checked against the order photo so the marking matches the report.
The 512 KB of flash on the LPC1813JBD144 is read at the true addresses, not a relocated image a tool might invent.
The Cortex-M3 clocked at 180 MHz on the LPC1813JBD144 is documented in the cover report so a replacement part boots identically.
The report includes the option or signature contents so the LPC1813JBD144 lock can be re-applied if required.
Where the LPC1813JBD144 arrived with corroded pins, we clean the LQFP144 before the first bench attempt.
Photographs of the 144-pin board are filed with the cover report so the LPC1813JBD144 package can be audited later.
We record the supply rail used on the LQFP144, because the LPC1813JBD144 flash timing is sensitive to voltage.
We note any CAN or USB use on the LQFP144, because the LPC1813JBD144 peripheral setup lives in the flash.
Calibration stored in non-volatile memory is recovered alongside the main array of the LPC1813JBD144.
We keep the LPC1813JBD144 away from strong fields on the bench, since flash can be disturbed by magnets.
Most LPC1813JBD144 jobs arrive with no compiler project, only the physical part and a failed recovery attempt.
We archive a checksum per region so a future read of the LPC1813JBD144 can be compared byte for byte.
Where decapsulation was needed the bare die of the LPC1813JBD144 is photographed before the lid is fully removed.
The Cortex-M3 clocked at 180 MHz on the LPC1813JBD144 runs the captured code in place, so the cover report notes the boot setup for a spare LQFP144.
The 104 KB runtime memory on the LPC1813JBD144 is captured live only when the assembly still comes up on power.
Where a live LQFP144 board is supplied we trace the serial lines before removing power from the LPC1813JBD144.
The customer gets a plain summary with the LPC1813JBD144 files, written for a non-engineer to follow.
