The LPC178x/7x is an ARM Cortex-M3 based microcontroller for embedded applications requiring a high level of integration and low power dissipation.
The Cortex-M3 is a next generation core that offers better performance than the ARM7 at the same clock rate and other system enhancements such as modernized debug features and a higher level of support block integration. The Cortex-M3 CPU incorporates a 3-stage pipeline and has a Harvard architecture with separate local instruction and data buses, as well as a third bus with slightly lower performance for peripherals. The Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branches.
The LPC178x/7x adds a specialized flash memory accelerator to accomplish optimal performance when executing code from flash. The LPC178x/7x operates at up to 120 MHz CPU frequency.
The peripheral complement of the LPC178x/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 (LPC178x only), Ethernet, USB Device/Host/OTG, a General Purpose DMA controller, five UARTs, three SSP controllers, three I2C-bus interfaces, one eight-channel, 12-bit ADC, a 10-bit DAC, 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, up to 165 general purpose I/O pins, and more.
