120 MHz, 32-bit

Microcontrollers with

Cortex-M3™ core,

LPC1700 series

Cortex-M3 based microcontrollers with

Ethernet, USB, CAN and 12-bit ADC

The LPC1700 series of low power cost-effective Cortex-M3 microcontrollers feature best-

in-class peripheral support such as Ethernet, USB 2.0 Host/OTG/Device, and CAN 2.0B.

Operating at speeds up to 120 MHz, they have up to 512 KB of FLASH, up to 64 KB of

SRAM, 12-bit A/D and 10-bit D/A converters as well as an internal RC oscillator.

Key Features

} ARM Cortex-M3 core

- Three I²C-bus interfaces with one supporting fast mode

plus (1 Mbit/s data rates)

- I²S interface for digital audio

- Up to 120 MHz operation

- Nested Vectored Interrupt Controller for fast

deterministic interrupts

} Analog Peripherals

- 12-bit Analog-to-Digital Converter with eight channels

- 10-bit Digital-to-Analog Converter

} Other Peripherals

- Wakeup Interrupt Controller allows automatic wake

from any priority interrupt

- Memory Protection Unit

- Real-Time Clock operating at < 1 uA

- Eight channel General Purpose DMA controller

- Up to 70 General Purpose I/O

- Four reduced power modes: Sleep, Deep-sleep,

Power-down and Deep power-down

} Memories

- Motor control PWM and Quadrature Encoder Interface to

support three-phase motors

- Up to 512 KB Flash memory

- Up to 64 KB SRAM

- Four 32-bit general purpose timers/counters

- 4 MHz internal RC oscillator trimmed to 1 % accuracy

} Serial Peripherals

- 10/100 Ethernet MAC

- USB 2.0 full-speed device/Host/ OTG controller

with on-chip PHY

The NXP LPC1700 series uses a low power, cost effective

Cortex-M3 core that operates at up to 120 MHz. Each device

has up to 512 KB of Flash and up to 64 KB of SRAM. The

LPC1700 series features a multi-layer AHB bus that allows

high-bandwidth peripherals such as Ethernet and USB to run

simultaneously, without impacting performance.

- Four UARTs with fractional baud rate generation,

RS-485. modem control I/O, and IrDA

- Two CAN 2.0B controllers

- Three SSP/SPI controllers

The LPC176x devices are available in an LQFP100 package

while the LPC175x MCUs are offered in an LQFP80 package.

The LPC1700 series is pin compatible with the popular

NXP LPC2300 series of ARM7 microcontrollers, allowing

designers to compare the M3 and ARM7 cores in the same

socket and simply choose the microcontroller that is best for

their application. With its wide array of peripherals and high

performance, the LPC1700 is ideal for e-Metering, lighting,

industrial networking, alarm systems, white goods and motor

control applications.
