Frequently asked questions
Is there a pin-compatible alternative within the NXP LPC43xx family?
The NXP LPC43xx series shares a common pinout footprint across several density options; qualification of a alternate within the same package and supply family requires confirmation against the target design's Flash/RAM budget and interface requirements.
What supply voltage does the LPC4337JET256Y require?
The part operates on a 2.2V to 3.6V supply rail — the lower rail ceiling relative to a 3.3V nominal design means the board-level LDO or DC-DC rail feeding VCC must stay within that window under all load conditions.
What is the LPC4337JET256Y's clock speed?
The LPC4337JET256Y is rated at 204MHz on the ARM Cortex-M4 core, with the Cortex-M0 co-processor capable of running at the same system clock frequency for peripheral management tasks.
