资源说明:LPC1700系列数据手册
The LPC17xx is an ARM Cortex-M3 based microcontroller for embedded applications
requiring a high level of integration and low power dissipation. The ARM Cortex-M3 is a
next generation core that offers system enhancements such as modernized debug
features and a higher level of support block integration.
The LPC17xx operates at up to an 100 MHz CPU frequency. The ARM Cortex-M3 CPU
incorporates a 3-stage pipeline and uses a Harvard architecture with separate local
instruction and data buses as well as a third bus for peripherals. The ARM Cortex-M3
CPU also includes an internal prefetch unit that supports speculative branches.
The peripheral complement of the LPC17xx includes up to 512 kB of flash memory, up to
64 kB of data memory, Ethernet MAC, a USB interface that can be configured as either
Host, Device, or OTG, 8 channel general purpose DMA controller, 4 UARTs, 2 CAN
channels, 2 SSP controllers, SPI interface, 3 I
2C interfaces, 2-input plus 2-output I
2S
interface, 8 channel 12-bit ADC, 10-bit DAC, motor control PWM, Quadrature Encoder
interface, 4 general purpose timers, 6-output general purpose PWM, ultra-low power RTC
with separate battery supply, and up to 70 general purpose I/O pins.
