Rev. 2.1 — 4 September 2012
Preliminary data sheet
1. General description
The LPC4357/53/37/33 are ARM Cortex-M4 based microcontrollers for embedded
applications which include an ARM Cortex-M0 coprocessor, up to 1 MB of flash and
136 kB of on-chip SRAM, 16 kB of EEPROM memory, advanced configurable peripherals
such as the State Configurable Timer (SCT) 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 LPC4357/53/37/33 operate at CPU
frequencies of up to 204 MHz.
The ARM Cortex-M4 is a next generation 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 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,
designed as a replacement for existing 8/16-bit microcontrollers, offers up to 204 MHz
performance with a simple instruction set and reduced code size.
