Product details

100 MHz Cortex-M3 — what it means for throughput

The LPC1768UKJ: At 100 MHz, this core executes single-cycle multiply and hardware divide, so control loops and protocol stacks (Ethernet TCP/IP, CANopen) run without a co-processor.

Connectivity and peripherals at a glance

The peripheral set includes CANbus, Ethernet, I²C, SPI, UART/USART, USB OTG, and IrDA — enough to talk to most fieldbus interfaces, sensors, and displays. The motor-control PWM and I²S audio interface extend its reach into servo drives and audio processing.

Frequently asked questions

What is LPC1768UKJ's listed speed?

The core runs at 100 MHz, which is the maximum clock for this Cortex-M3 implementation in the LPC17xx series.

What compliance documentation does NXP provide for LPC1768UKJ?

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 and IEC certifications are not listed for this component; check the NXP compliance portal for the latest declarations.
