Rev. 1 — 17 September 2012

Objective data sheet

1. General description

The LPC408x/7x is an ARM Cortex-M4 based digital signal controller for embedded

applications requiring a high level of integration and low power dissipation.

The ARM Cortex-M4 is a next generation core that offers system enhancements such as

low power consumption, enhanced debug features, and a high level of support block

integration. The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard

architecture with separate local instruction and data buses as well as a third bus for

peripherals, and includes an internal prefetch unit that supports speculative branching.

The ARM Cortex-M4 supports single-cycle digital signal processing and SIMD

instructions. A hardware floating-point processor is integrated in the core for several

versions of the part.

The LPC408x/7x adds a specialized flash memory accelerator to accomplish optimal

performance when executing code from flash. The LPC408x/7x is targeted to operate at

up to 120 MHz CPU frequency.

The peripheral complement of the LPC408x/7x includes up to 512 kB of flash program

memory, up to 96 kB of SRAM data memory, up to 4032 byte of EEPROM data memory,

External Memory controller (EMC), LCD, Ethernet, USB Device/Host/OTG, an SPI Flash

Interface (SPIFI), a General Purpose DMA controller, five UARTs, three SSP controllers,

three I²C-bus interfaces, a Quadrature Encoder Interface, four general purpose timers,

two general purpose PWMs with six outputs each and one motor control PWM, an

ultra-low power RTC with separate battery supply and event recorder, a windowed

watchdog timer, a CRC calculation engine and up to 165 general purpose I/O pins.

The analog peripherals include one eight-channel 12-bit ADC, two analog comparators,

and a DAC.

The pinout of LPC408x/7x is intended to allow pin function compatibility with the

LPC24xx/23xx as well as the LPC178x/7x families.

2. Features and benefits

 Functional replacement for LPC23xx/24xx and LPC178x/7x family devices.

 ARM Cortex-M4 core:

 ARM Cortex-M4 processor, running at frequencies of up to 120 MHz.

 ARM Cortex-M4 built-in Memory Protection Unit (MPU) supporting eight regions.

 ARM Cortex-M4 built-in Nested Vectored Interrupt Controller (NVIC).

 Hardware floating-point unit (not all versions).

 Non-maskable Interrupt (NMI) input.
