Product data sheet
1. General description
The LPC4350/30/20/10 are ARM Cortex-M4 based microcontrollers for embedded
applications which include an ARM Cortex-M0 coprocessor, up to 264 kB of SRAM,
advanced configurable peripherals such as the State Configurable Timer/PWM
(SCTimer/PWM) 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. The LPC4350/30/20/10 operate at CPU frequencies of up to 204
The ARM Cortex-M4 is a 32-bit core that offers system enhancements such as low power
consumption, enhanced debug features, and a high level of support block integration. 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 ARM Cortex-M0 coprocessor is an energy-efficient and easy-to-use 32-bit core which
is code- and tool-compatible with the Cortex-M4 core. The Cortex-M0 coprocessor offers
up to 204 MHz performance with a simple instruction set and reduced code size. In
LPC43x0, the Cortex-M0 coprocessor hardware multiply is implemented as a 32-cycle
See Section 17 “References” for additional documentation.
