1.General descriptionThe LPC1769/68/67/66/65/64/63 are ARM Cortex-M3 based microcontrollers forembedded applications featuring a high level of integration and low power consumption.The ARM Cortex-M3 is a next generation core that offers system enhancements such asenhanced debug features and a higher level of support block integration.The LPC1768/67/66/65/64/63 operate at CPU frequencies of up to 100 MHz. TheLPC1769 operates at CPU frequencies of up to 120 MHz. The ARM Cortex-M3 CPUincorporates a 3-stage pipeline and uses a Harvard architecture with separate localinstruction and data buses as well as a third bus for peripherals. The ARM Cortex-M3CPU also includes an internal prefetch unit that supports speculative branching.The peripheral complement of the LPC1769/68/67/66/65/64/63 includes up to 512 kB offlash memory, up to 64 kB of data memory, Ethernet MAC, USB Device/Host/OTGinterface, 8-channel general purpose DMA controller, 4 UARTs, 2 CAN channels, 2 SSPcontrollers, SPI interface, 3 I2C-bus interfaces, 2-input plus 2-output I2S-bus interface,8-channel 12-bit ADC, 10-bit DAC, motor control PWM, Quadrature Encoder interface,four general purpose timers, 6-output general purpose PWM, ultra-low power Real-TimeClock (RTC) with separate battery supply, and up to 70 general purpose I/O pins.The LPC1769/68/67/66/65/64/63 are pin-compatible to the 100-pin LPC236xARM7-based microcontroller series.2.Features and benefits ARM Cortex-M3 processor, running at frequencies of up to 100 MHz(LPC1768/67/66/65/64/63) or of up to 120 MHz (LPC1769).
