The NXP LPC1769FBD100K is a 32-bit ARM Cortex-M3 microcontroller running at 120 MHz, with 512 KB of Flash and 64 KB of SRAM. It targets industrial control, motor drive, and communication gateway applications where Ethernet, USB OTG, and CANbus are needed on a single chip. The 100-LQFP package gives you 70 I/O lines and the full peripheral set without needing a BGA reflow. The 120 MHz core clock is the highest in the LPC17xx family, so bus timing for tight control loops and protocol stacks (TCP/IP, CANopen) closes with margin. The 512 KB Flash holds a full RTOS plus application code; 64 KB SRAM handles packet buffers and stack without external memory.
Temperature grade and environment
Rated -40°C to 85°C ambient.
Analog and control peripherals
Eight 12-bit SAR ADC channels and one 10-bit DAC cover analog feedback for current sensing or set-point generation. The motor control PWM includes dead-time insertion and fault input, so it drives a 3-phase inverter bridge directly from the timer block.
