General description

The LPC1768/66/65/64 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 LPC1768/66/65/64 operate at CPU frequencies of up to 100 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 LPC1768/66/65/64 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 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, 4 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 LPC1768/66/65/64 are pin-compatible to the 100-pin LPC236x ARM7-based

microcontroller series.

Features

I ARM Cortex-M3 processor, running at frequencies of up to 100 MHz. A Memory

Protection Unit (MPU) supporting eight regions is included.

I ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).

I Up to 512 kB on-chip ﬂash programming memory. Enhanced ﬂash memory accelerator

enables high-speed 100 MHz operation with zero wait states.

I In-System Programming (ISP) and In-Application Programming (IAP) via on-chip

bootloader software.

I On-chip SRAM includes:

N 32/16 kB of SRAM on the CPU with local code/data bus for high-performance CPU

access.

N Two/one 16 kB SRAM blocks with separate access paths for higher throughput.

These SRAM blocks may be used for Ethernet (LPC1768/66/64 only), USB, and

DMA memory, as well as for general purpose CPU instruction and data storage.
