The LPC178x/7x is an ARM Cortex-M3 d microcontroller for ded 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 is targeted to operate 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. The pinout of LPC178x/7x is intended to allow
pin function compatibility with the LPC24xx and LPC23xx
