The LPC1830FET100 is an NXP LPC18xx part: a Cortex-M3 at 180 MHz with no on-chip flash and 200 KB SRAM block in a TFBGA100. The contact desk handles decapsulation and the checked archive for the LPC1830FET100 TFBGA100.
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 LPC1830FET100 is on-die flash or SPIFI image first, then the OTP region, then any live RAM, then a second pass.
Peripheral Set
The LPC18xx character of the LPC1830FET100 comes from the HSADC near 80 Msps and the SCT state-configurable timer built in hardware. What makes a LPC1830FET100 more than a generic Cortex-M3 is the HSADC and the SCT, both configured by code in no on-chip flash. The STM32 readout case shows how a cloned board must reconstruct the clock source for the LPC1830FET100.
Flash And Working Memory
The LPC1830FET100 maps no on-chip flash for execution and 200 KB SRAM block for data, with an EMC that can attach off-die SDRAM. Because the LPC1830FET100 includes an external-memory controller, a board may place code or data in off-chip SDRAM through the EMC. A PIC clone example shows how timer configuration lives in a few registers a hex can rebuild.
Where The Read Protection Lives
The LPC1830FET100 guards its array with a code-read-protection bit in the program flash signature and OTP area, a reversible setting. NXP’s CRP on the LPC1830FET100 is a bit in the program flash signature region that blocks debugger reads but never erases the array. The memory-type comparison explains why flash and option regions are archived separately on the TFBGA100.
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 LPC1830FET100 TFBGA100. A related write-up on the LPC1837FET256 covers the rest of this part family.
A second confirming read is offered when a customer wants proof no weak cell moved on the LPC1830FET100 TFBGA100.
Calibration stored in non-volatile memory is recovered alongside the main array of the LPC1830FET100.
Where decapsulation was needed the bare die of the LPC1830FET100 is photographed before the lid is fully removed.
The LPC1830FET100 is photographed next to a scale so the package size is unambiguous in the archive.
The delivery keeps the original protection state of the LPC1830FET100, so a later comparison reuses the same settings.
The report includes the option area or signature contents so the LPC1830FET100 lock can be re-applied if required.
A small reference card travels with the LPC1830FET100 so the bench knows the expected die orientation.
We note the batch code on the TFBGA100 LPC1830FET100, which sometimes explains a quirk in the silicon revision.
The customer receives the files with a short note on reflashing the TFBGA100 without tripping the read lock again.
For a 100-pin LPC1830FET100 the alternate-function pins are decoded from the dump, not guessed from the silk.
We keep the bench notes with the order so the LPC1830FET100 protection level is never lost between reads.
We separate the no on-chip flash from working memory in the archive, since mixing them hides the read lock state.
A LPC1830FET100 that has been partially read elsewhere often arrives with the option area region already corrupted.
We keep the LPC1830FET100 away from strong fields on the bench, since flash can be disturbed by magnets.
The 100-pin LPC1830FET100 is logged against its order code so a repeat job reuses the same bench setup.
A recovered LPC1830FET100 is cross-checked against the order photo so the marking matches the report.
A 100-pin LPC1830FET100 that failed a previous shop usually still yields to a careful second pass.
We confirm the 100-pin count against the marking so the extracted LPC1830FET100 netlist lines up with the board.
The recovered files for the LPC1830FET100 are named by order number, never by the chip marking alone.
The no on-chip flash on the LPC1830FET100 is read at the true addresses, not a relocated image a tool might invent.
A TFBGA100 LPC1830FET100 sent cold in foam reads more reliably than one that travelled powered and warm.
We note any CAN or USB use on the TFBGA100, because the LPC1830FET100 peripheral setup lives in the flash.
