32-bit ARM Cortex-M3 MCU; up to 512 kB flash and 64 kB
SRAM with Ethernet, USB 2.0 Host/Device/OTG, CAN

General description
The LPC1758/56/54/52/51 are ARM Cortex-M3 based microcontrollers for embedded　applications featuring a high level of integration and low power consumption. The ARM　Cortex-M3 is a next generation core that offers system enhancements such as enhanced　debug features and a higher level of support block integration.The LPC1758/56/54/52/51 operate at CPU frequencies of up to 100 MHz. The ARM　Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with　separate local instruction and data buses as well as a third bus for peripherals. The ARM　Cortex-M3 CPU also includes an internal prefetch unit that supports speculative　branching.

The peripheral complement of the LPC1758/56/54/52/51 includes up to 512 kB of flash　memory, up to 64 kB of data memory, Ethernet MAC, USB Device/Host/OTG interface,8-channel general purpose DMA controller, 4 UARTs, 2 CAN channels, 2 SSP controllers,SPI interface, 3 I2C-bus interfaces, 2-input plus 2-output I2S-bus interface, 6 channel　12-bit ADC, 10-bit DAC, motor control PWM, Quadrature Encoder interface, 4 general　purpose timers, 6-output general purpose PWM, ultra-low power Real-Time Clock (RTC)　with separate battery supply, and up to 52 general purpose I/O pins.
