Multimedia Evaluation Board with LPC4357
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 Cortex-M4/M0 based LPC4357 microcontroller. The LPC4357 is an ARM Cortex-M4 based microcontroller for embedded applications which include 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 the bandwidth of the Cortex-M4 core. TheLPC4357 also includes 1 MB Flash memory, 136 kB of data memory, two High Speed USB 2.0 Host/OTG/Devices, advanced configurable peripherals such as the State Configurable Timer (SCT), Serial General Purpose I/O (SGPIO), and SPI Flash Interface (SPIFI) as well as Ethernet, LCD, an external memory controller and multiple digital and analog peripherals.
