Product details
Overview
LPC1768FET100,551 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller in a 100-ball TFBGA package, operating at up to 100 MHz with 512 kB flash, 64 kB SRAM, dual CAN 2.0B interfaces, USB 2.0 Host/Device/OTG, and Ethernet MAC - deployed in industrial motor control and networked white goods.
For engineers reviewing the LPC1768FET100,551 datasheet, LPC1768FET100,551 pinout, LPC1768FET100,551 application, or LPC1768FET100,551 equivalent, key selection criteria include TFBGA100 footprint compatibility, 100 MHz real-time deterministic execution, integrated Ethernet+USB+CAN for multi-protocol edge nodes, and support for I2S audio and 12-bit ADC-driven sensor fusion.
Technical Context
The LPC1768FET100,551 implements a Harvard-architecture Cortex-M3 core with 3-stage pipeline, integrated MPU supporting eight memory regions, and NVIC for low-latency interrupt handling. Its AHB multilayer matrix enables concurrent CPU, GPDMA, Ethernet, and USB access without arbitration delay.
Peripheral integration includes a dedicated GPDMA controller servicing UARTs, SSP, I2S, ADC, DAC, and timers; split APB buses reduce CPU-DMA contention; and clock generation supports independent peripheral dividers for dynamic power scaling across Sleep, Deep-sleep, Power-down, and Deep power-down modes.
