Frequently asked questions
Does the ROMless LPC43S70FET100E require an external flash chip for boot?
Yes. The part has no internal program memory (ROMless designation,), so every board must include an external SPI or QSPI flash device. This is a mandatory BOM addition, not optional — plan the boot-memory slot and pinout alongside the MCU.
Can I substitute a flash-equipped LPC43xx variant for the LPC43S70FET100E?
Only if pinout and peripheral mapping match your board. The base product LPC43S70 exists in both ROMless and flash-equipped versions — confirm the exact suffix before treating any variant as a drop-in swap. The ROMless part requires external boot memory that the flash version does not.
What is the operating temperature range of the LPC43S70FET100E?
-40°C to 85°C ambient. This covers standard industrial control environments but is not the extended -40°C to 125°C grade found in some LPC43xx automotive variants. Confirm your enclosure thermal model before deployment in poorly ventilated panels.
