The MYD-LPC4357 is a full-featured development board with an NXP LPC4357FET256 ARM Cortex-M4 processor running at 204 MHz. The board integrates all core components, memory, interfaces and tested software source code, enabling you to create a reliable prototype.

The LPC4357 processor has on-chip 1MB Flash, 136KB SRAM for code and data use, two 32KB SRAM blocks with separate bus access, 32KB ROM containing boot code and on-chip software drivers, and 32-bit OTP memory for customer use. The MYD-LPC4357 board adds 32MB SDRAM, 2MB Nor Flash and 4MB SPI Flash. Peripheral interfaces on board include High-speed USB Host/OTG, audio input/output, 10/100Mbps Ethernet, CAN, JTAG, LCD Module, UART, MicroSD and user GPIO pins. The CPU provides a State Configurable Timer, Serial General-Purpose I/O, and SPI Flash Interface.

See the NXP LPC4357FET256 Page for a datasheet and other documentation on the CPU.
