The LPC4357 is a member of the LPC43xx family of products with the following performance features. The LPC43xx is an ARM Cortex-M4 microcontroller for embedded applications, which includes an ARM Cortex-M0 coprocessor, up to 1 MB of flash, up to 264 KB of SRAM, advanced configurable peripherals such as State Configurable Timer (SCT) and Serial General Purpose I/O (SGPIO) interfaces, 2 high-speed USB controllers, Ethernet, LCD, external memory controller, and a variety of analog and digital peripherals. The LPC43xx operates at CPU frequencies up to 204 MHz. The ARM Cortex-M4 is a new generation of 32-bit cores that provides system enhancements such as low power consumption, enhanced debugging capabilities, and a high level of support block integration. The ARM Cortex-M4 CPU uses a 3-stage pipeline, adopts a Harvard architecture, has independent local instruction and data buses and a third bus for peripherals, includes an internal prefetch unit, and supports speculative branches. The ARM Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. The core integrates a hardware floating point processor. The ARM Cortex-M0 coprocessor is an energy efficient and easy to use 32-bit core that is code and tool compatible with the Cortex-M4 core. With a simple instruction set and reduced code size, the Cortex-M0 coprocessor is designed as a replacement for existing 16-bit multi-function microcontrollers and provides performance up to 204 MHz.
