2 Introduction
Thank you for buying Embedded Artists’ LPC4357 Developer’s Kit based on NXP’s ARM dual-core
Cortex-M4/M0 LPC4357 microcontroller.
This document is a User’s Guide that describes the LPC4357 OEM Board and the OEM Base Board
hardware design, which together form the LPC4357 Developer’s Kit.
2.1 Features
Embedded Artists’ LPC4357 OEM Board lets you get up-and-running quickly. The small form factor
OEM board offers many unique features that ease your learning curve and program development. The
board has been designed for OEM applications with volume discount available.
NXP's ARM dual-core Cortex-M4/M0 LPC4357 microcontroller in BGA package, with 1 MByte
program FLASH and 136 KByte SRAM
16 MBit QSPI flash on SPIFI interface
External FLASH memories: 128 MB NAND FLASH
External data memory: 32 MB SDRAM (32-bit databus width)
12.0000 MHz crystal for maximum execution speed and standard serial bit rates, including
CAN and USB requirements
32.768kHz RTC crystal
100/10M Ethernet PHY/interface based on SMSC LAN8720
Buffered 32-bit data bus for external expansion
1 Kbit E2PROM with EUI-48™ number (for Ethernet MAC address)
200 pos expansion connector (SODIMM-200 format, 0.6mm pitch)
Most LPC4357 pins available (see LPC4357 OEM Board datasheet for details)
+3.3V only powering
Onboard reset generation
Compact SODIMM format: 68 x 50 mm
Eight layer PCB design for best EMC performance, with controlled impedance and length
matched routing for critical signals
There is an accompanying OEM Base Board that can be used for initial prototyping work. The features
of the board are:
Interfaces and Connectors
200 pos, 0.6mm pitch SODIMM connector for OEM Board
LCD expansion connector with control signals for touch screen interface
Expansion connector with all OEM Board signals
Ethernet connector (RJ45)
CAN interface & connector (provision for second CAN interface, but not mounted)
USB1: OTG or Host interface & connector
