Product details
Frequently asked questions
What is the maximum clock speed of LPC1315FHN33?
The core runs at 72 MHz, which is the maximum clock speed for this ARM Cortex-M3 part.
What is the operating voltage range of LPC1315FHN33?
The supply voltage range is 2V to 3.6V, making it compatible with standard 3.3V logic rails.
Is LPC1315FHN33 pin compatible with LPC1313FHN33?
Both parts share the same 32-HVQFN package and pinout within the LPC13xx family, so they are pin-compatible. The difference is Flash and RAM density — the LPC1313 carries 32 KB Flash / 8 KB RAM, matching the LPC1315's memory map, so a direct swap is feasible for the same firmware image.
