On-chip connectivity includes CANbus, USB OTG, multiple SPI/I²C/UART interfaces, and an external bus interface (EBI/EMI) for expanding memory or connecting FPGAs. The 49 GPIOs are enough for a mid-complexity control board with a local display, keypad, and a handful of sensors. The internal oscillator keeps the BOM lean for applications that do not require a precision external clock source. Data converters: a 4-channel 10-bit ADC and a single 10-bit DAC.

Frequently asked questions
What is LPC4325JET100551's listed speed?
The core runs at 204 MHz, shared between the Cortex-M4 and Cortex-M0. That clock rate gives the M4 enough headroom for DSP loops and protocol processing while the M0 handles time-critical I/O or safety tasks.
What compliance documentation does NXP provide for LPC4325JET100551?
NXP provides RoHS and REACH compliance declarations for this part. The 100-TFBGA package is lead-free and meets the current EU directive requirements. UL or IEC certification is not listed in the standard documentation set.
