LPC51 in NXP LPC Family
The LPC51 series by NXP Semiconductors is a family of high-efficiency, power-optimized microcontrollers based on the ARM Cortex-M0+ core. Designed as a bridge between entry-level 8/16-bit MCUs and high-performance 32-bit platforms, the family focuses on maximizing processing throughput per milliwatt. Operating at speeds up to 100MHz, these devices provide a scalable solution for power-constrained embedded systems that require robust connectivity options like USB and high-speed serial peripherals without the overhead of more complex multi-core architectures.
Variants in This Sub-Family
Variants within the LPC51 sub-family primarily differ based on integrated flash memory capacity and SRAM density, ranging from 128KB to 256KB of flash. Package options also vary significantly, including LQFP48, LQFP64, and smaller VFBGA options to suit different PCB footprint requirements. Some specific models, like the LPC51U68, emphasize USB connectivity, while others focus on pin-constrained general-purpose I/O and specific serial interface counts through the flexible Flexcomm peripheral system.
