NXP Semiconductors LPC1778 & LPC1788 32-bit Microcontrollers

NXP Semiconductors LPC1778 and LPC1788 32-bit Microcontrollers are Arm® Cortex®-M3 MCUs ideal for for embedded applications requiring a high level of integration and low power dissipation. 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 LPC1778 and LPC1788 MCUs add a specialized flash memory accelerator to accomplish optimal performance when executing code from flash. These devices operate at up to 120MHz CPU frequency.

The peripheral complement of the LPC1778 and LPC1788 MCUs includes up to 512kB of flash program memory, up to 96kB 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 the LPC1778 and LPC1788 MCUs is intended to allow pin function compatibility with the LPC24xx and LPC23xx.
