LPC1751FBD80 - Brand New NXP Semiconductors Microcontrollers
-
Description
The LPC1759/58/56/54/52/51 are microcontrollers from NXP Semiconductors with an ARM Cortex-M3 processor. These microcontrollers are designed for embedded applications and feature low power consumption. The ARM Cortex-M3 processor provides system enhancements such as improved debugging features and a higher level of support block integration. The LPC1758/56/57/54/52/51 operate at CPU frequencies of up to 100 MHz and the LPC1759 operates at CPU frequencies of up to 120 MHz. These microcontrollers have a built-in Memory Protection Unit (MPU) and Nested Vectored Interrupt Controller (NVIC) for better performance. The LPC1759/58/56/54/52/51 have a wide range of peripherals, including Ethernet MAC, USB Device/Host/OTG interface, General Purpose DMA controller, UARTs, CAN channels, SSP controllers, SPI interface, I2C-bus interfaces, I2S-bus interface, ADC, DAC, motor control PWM, Quadrature Encoder interface, general-purpose timers, general-purpose PWM, ultra-low power Real-Time Clock (RTC), and general-purpose I/O pins.
