LPC4300系列ARM双核微控制器产品数据手册

The LPC4350/30/20/10 are ARM Cortex-M4 based microcontrollers for embedded
applications. The ARM Cortex-M4 is a next generation core that offers system
enhancements such as low power consumption, enhanced debug features, and a high
level of support block integration.
The LPC4350/30/20/10 operate at CPU frequencies of up to 150 MHz. The ARM
Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture with
separate local instruction and data buses as well as a third bus for peripherals, and
includes an internal prefetch unit that supports speculative branching. The ARM
Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A
hardware floating-point processor is integrated in the core.
The LPC4350/30/20/10 include an ARM Cortex-M0 coprocessor, up to 264 kB of data
memory, advanced configurable peripherals such as the State Configurable Timer (SCT)
and the Serial General Purpose I/O (SGPIO) interface, two High-speed USB controllers,
Ethernet, LCD, an external memory controller, and multiple digital and analog peripherals
