1.General descriptionThe LPC408x/7x is an ARM Cortex-M4 based digital signal controller for embeddedapplications requiring a high level of integration and low power dissipation.The ARM Cortex-M4 is a next generation core that offers system enhancements such aslow power consumption, enhanced debug features, and a high level of support blockintegration. The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvardarchitecture with separate local instruction and data buses as well as a third bus forperipherals, and includes an internal prefetch unit that supports speculative branching.The ARM Cortex-M4 supports single-cycle digital signal processing and SIMDinstructions. A hardware floating-point processor is integrated in the core for severalversions of the part.The LPC408x/7x adds a specialized flash memory accelerator to accomplish optimalperformance when executing code from flash. The LPC408x/7x is targeted to operate atup to 120 MHz CPU frequency.The peripheral complement of the LPC408x/7x includes up to 512 kB of flash programmemory, 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 FlashInterface (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, anultra-low power RTC with separate battery supply and event recorder, a windowedwatchdog 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 theLPC24xx/23xx as well as the LPC178x/7x families.2.Features and benefits Functional replacement for LPC23xx/24xx and LPC178x/7x family devices.
