The LPC1759FBD80K is a high-performance 32-bit microcontroller from NXP's LPC17xx series, featuring an ARM Cortex-M3 core with a maximum operating frequency of 120MHz. It comes in an 80-LQFP (12×12mm) package, with the suffix "K" indicating tray packaging. Memory resources include 512KB on-chip Flash and 64KB SRAM, supporting ISP/IAP in-system/ in-application programming. It integrates an 8-channel general-purpose DMA to reduce CPU load. With high peripheral integration, it includes a 10/100 Ethernet MAC, USB2.0 Full-Speed Host/Device/OTG, and dual CAN2.0B interfaces. It offers multiple UART/I2C/SSP/SPI/I2S communication interfaces. Analog peripherals include a 12-bit high-speed ADC and a 10-bit DAC. Dedicated motor-control PWM, a quadrature encoder interface, an independent RTC, and multiple general-purpose timers are also integrated, along with 52 configurable GPIOs. Operating voltage ranges from 2.4V to 3.6V, with an industrial temperature range of -40℃ to +85℃. It supports multi-level low-power modes, power-on reset, watchdog, and other system functions. It is widely used in high-performance embedded applications requiring multi-bus interconnectivity, such as industrial gateways, Ethernet IoT devices, USB industrial peripherals, CAN bus devices, audio processing, and multi-axis motor control.
