LPC43S50FET256: 32-bit ARM Cortex-M4/M0 flashless MCU with security features; 264 kB SRAM; Ethernet; two HS USBs; LCD

The LPC43S50FET256 is a ARM Cortex-M4 based microcontroller for embedded applications which includes an ARM Cortex-M0 coprocessor, 264 kB of SRAM, security features with AES engine, 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 LPC43S50FET256 operates 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 unit 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 LPC43Sx0, the Cortex-M0 coprocessor hardware multiply is implemented as a 32-cycle iterative multiplier.
