1. General description
The LPC1769/68/67/66/65/64/63 are ARM Cortex-M3 based microcontrollers for
embedded 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 as
enhanced 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. The
LPC1769 operates at CPU frequencies of up to 120 MHz. 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 branching.
The peripheral complement of the LPC1769/68/67/66/65/64/63 includes up to 512 kB of
flash memory, up to 64 kB of data memory, Ethernet MAC, USB Device/Host/OTG
interface, 8-channel general purpose DMA controller, 4 UARTs, 2 CAN channels, 2 SSP
controllers, SPI interface, 3 I
2
C-bus interfaces, 2-input plus 2-output I
2
S-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-Time
Clock (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 LPC236x Arm7-based
microcontroller series.
