LPC1788FBD208

1. General description

The LPC178x/7x is an ARM Cortex-M3 based microcontroller for embedded applications

requiring a high level of integration and low power dissipation.

The ARM 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 ARM 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 ARM 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, 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 analog peripherals include one eight-channel 12-bit ADC and a 10-bit DAC.

The pinout of LPC178x/7x is intended to allow pin function compatibility with the LPC24xx

and LPC23xx.
