The LPC43S30FET100 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, an external memory controller,
and multiple digital and analog peripherals. The LPC43S30FET100 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.
