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. The 512 KB Flash is enough for a full RTOS plus application image; the 64 KB RAM handles moderate data buffering — if your application needs larger frame buffers or a heavy GUI, plan for external SRAM or a part with more RAM.
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. Brown-out detect, POR, and a watchdog timer are built in, so external supervisory ICs are optional for non-safety-critical designs.
