LPC435x/3x/2x/1x  
32-bit ARM Cortex-M4/M0 MCU; up to 1 MB flash and 136 kB  
SRAM; Ethernet, two High-speed USB, LCD, EMC  
Rev. 5.3 — 15 March 2016  
Product data sheet  
1. General description  
The LPC435X_3X_2X_1X are ARM Cortex-M4 based microcontrollers with Floating Point  
Unit (FPU) for embedded applications which include an ARM Cortex-M0 coprocessor, up  
to 1 MB of flash and 136 kB of on-chip SRAM, 16 kB of EEPROM memory, two  
high-speed USB controllers, Ethernet, LCD, an external memory controller, a quad SPI  
Flash Interface (SPIFI) that supports execute-in-place, advanced configurable peripherals  
such as the State Configurable Timer (SCTimer/PWM) and the Serial General Purpose  
I/O (SGPIO) interface, and multiple digital and analog peripherals. The  
LPC435X_3X_2X_1X operate at CPU frequencies of up to 204 MHz.  
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 into the core.  
The ARM Cortex-M0 coprocessor is an energy-efficient and easy-to-use 32-bit core,  
which is upward code- and tool-compatible with the Cortex-M4 core. It is ideal for handling  
control or peripheral handling to free up the Cortex-M4 for real-time processing. The  
Cortex-M0 coprocessor offers up to 204 MHz performance with a simple instruction set  
and reduced code size. In LPC43xx, the Cortex-M0 coprocessor hardware multiply is  
implemented as a 32-cycle iterative multiplier.  
For additional documentation related to the LPC43xx parts, see Section 17.  
2. Features and benefits
