LPC1751FBD80K - 100MHz Cortex-M3 32KB MCU | NXP
The NXP LPC1751FBD80K is a 32-bit ARM Cortex-M3 microcontroller operating up to 100 MHz, with 32 KB of flash memory and 8 KB of data memory, in an 80-pin LQFP package measuring 12 x 12 mm. Its integrated peripherals include USB Device, an 8-channel DMA controller, four UARTs, one CAN channel, two SSP channels, one SPI, two I2C, and an 8-channel 12-bit ADC.
A microcontroller is a programmable system-on-chip that combines a processor core, nonvolatile program memory, data memory, and peripherals in one package. The LPC1751 belongs to the ARM Cortex-M3 microcontroller -> embedded processor -> semiconductor hierarchy. Its combination of deterministic peripheral access, USB connectivity, serial interfaces, and motor-control resources makes it suitable for compact embedded control systems.
Key features include 100 MHz operation, 32 KB flash, 8 KB SRAM, a 12-bit ADC, USB Device connectivity, and extensive serial communications. The NXP product listing identifies four general-purpose timer blocks, motor-control PWM, and a quadrature encoder interface. These resources allow one controller to coordinate analog measurements, communications, motion functions, and general-purpose timing.
The ARM Cortex-M3 architecture provides a 32-bit processing environment while retaining low-power embedded operation. The integrated peripherals reduce the number of external devices required for USB, CAN, UART, SPI, I2C, ADC, DMA, and PWM functions. Designers must still validate clock, voltage, pin-multiplexing, and peripheral-configuration requirements against the manufacturer datasheet before finalizing a PCB or firmware design.
Typical applications include industrial control equipment, USB-connected data acquisition, motor and encoder control, serial gateways, instrumentation, and embedded communications systems. The ADC supports analog sensing, while CAN and multiple serial interfaces support communication with sensors, actuators, and external controllers.
A key design consideration is firmware and peripheral migration: changing the MCU, bootloader, pin mux, clock tree, or USB implementation may require software changes even when the replacement offers similar features. Validate the 80-LQFP footprint, exposed electrical requirements, and toolchain support before committing to a design.
This product record combines verified manufacturer and distributor information with practical selection guidance, interface context, design notes, and procurement-oriented references. It distinguishes LPC1751FBD80K from a generic 32-bit MCU by focusing on its 100 MHz Cortex-M3 core, 32 KB flash, 8 KB SRAM, USB, CAN, serial interfaces, ADC, DMA, motor-control PWM, and quadrature encoder capabilities.
