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.
