The NXP LPC1752FBD80K is a 32-bit ARM Cortex-M3 microcontroller from the LPC17xx series, clocked at 100 MHz with 64 KB of Flash program memory and 16 KB of SRAM. It carries 52 GPIOs, a 6-channel 12-bit SAR ADC, and a peripheral set built for industrial control: CANbus, USB, I²C, SPI, UART, and SSP. The internal oscillator and brown-out detect reduce external component count on a two-layer board. This is the 80-pin LQFP variant in a 12x12 mm body, rated for -40 to 85°C operation on a 2.4 to 3.6 V supply.
100 MHz Cortex-M3 — what it buys you on the bus
100 MHz core speed on the ARM Cortex-M3 gives single-cycle multiply and hardware divide, plus a 3-stage pipeline with branch speculation. For a control loop with CAN messaging and a sensor read over SPI, that headroom means the ADC interrupt doesn't push the protocol stack past its jitter budget. The 16 KB SRAM is the tighter resource — USB with double-buffered endpoints or a CANopen stack with several PDOs will eat into that quickly; plan the buffer allocation early.
CANbus, USB, I²C, SPI, UART, and SSP cover the common industrial interfaces. The motor control PWM and the DMA controller let this part drive a small BLDC or stepper without an external motion controller. Six 12-bit SAR ADC channels sample at rates adequate for current-sense and temperature monitoring in a motor-drive application.
