The LPC43S37JET100 is a Arm Cortex-M4 based microcontroller for embeddedapplications which includes an Arm Cortex-M0 coprocessor, 1 MB of flash and136 kB of on-chip SRAM, 16 kB of EEPROM memory, security features with AES engine,a quad SPI Flash Interface (SPIFI), advanced configurable peripherals such as the StateConfigurable Timer (SCT) and the Serial General Purpose I/O (SGPIO) interface, twoHigh-speed USB controllers, Ethernet, an external memory controller, and multipledigital and analog peripherals. The LPC43S37JET100 operates at CPU frequencies of up to204 MHz.

The Arm Cortex-M4 is a 32-bit core that offers system enhancements such as low powerconsumption, enhanced debug features, and a high level of support block integration. TheArm Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture withseparate local instruction and data buses as well as a third bus for peripherals, andincludes an internal prefetch unit that supports speculative branching. The Arm Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. Ahardware floating-point unit is integrated in the core. The Arm Cortex-M4 withfloating-point unit is often referred to as M4F.

The Arm Cortex-M0 coprocessor is an energy-efficient and easy-to-use 32-bit core whichis upward code- and tool-compatible with the Cortex-M4 core. The Cortex-M0coprocessor, designed as a replacement for existing 8/16-bit microcontrollers, offers up to204 MHz performance with a simple instruction set and reduced code size.
