General description
The LPC4370 are ARM Cortex-M4 based microcontrollers for embedded applications
which include an ARM Cortex-M0 coprocessor and an ARM Cortex-M0 subsystem for
managing peripherals, 282 kB of SRAM, advanced configurable peripherals such as the
State Configurable Timer (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, including a high-speed 12-bit ADC. The
LPC4370 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 in the core.
The LPC4370 include an application ARM Cortex-M0 coprocessor and a second ARM
Cortex-M0 subsystem for managing the SGPIO and SPI peripherals. The ARM Cortex-M0
core is an energy-efficient and easy-to-use 32-bit core which is code- and tool-compatible
with the Cortex-M4 core. Both Cortex-M0 cores offer up to 204 MHz performance with a
simple instruction set and reduced code size. In LPC43x0, the Cortex-M0 coprocessor
hardware multiply is implemented as a 32-cycle iterative multiplier.
