NXP development kit based on the dual-core LPC4357 microcontroller

January 10, 2013

NXP and element14 present the LPC4357-EVB multimedia evaluation kit, exclusively available from element14. Based on ARM® Cortex™-M4 and Cortex™-M0 processors, the LPC4357-EVB is a high-performance, low-cost solution for developing DSP and MCU applications within a single architecture and development environment.

The LPC4357-EVB is equipped with NXP's dual-core LPC4357 microcontroller. The LPC4357 is an ARM Cortex-M4 based microcontroller for embedded applications and includes an ARM Cortex-M0 coprocessor. It also features 256 Mbit (32 MB) of serial Flash memory from Spansion. The QSPI Flash is connected to the LPC4357’s unique SPI Flash Interface which allows the M4 or M0 core to execute from the QSPI or access large tables of data or images.

The Cortex-M4 processor combines the benefits of a microcontroller with high-performance digital signal processing features such as single-cycle MAC, single instruction multiple data (SIMD) techniques, saturating arithmetic and a floating point unit.

The Cortex-M0 coprocessor off-loads many of the data movement and I/O handling duties that can drain bandwidth from the Cortex-M4 core. The LPC4357 also includes 1 MB Flash memory, 136 KB of data memory, two high-speed USB 2.0 host / OTG / devices and advanced configurable peripherals such as the state configurable timer (SCT), Serial General Purpose I/O (SGPIO), and SPI flash Interface (SPIFI). Other features are Ethernet, LCD, an external memory controller and multiple digital and analog peripherals.
