LPC4357 Developer’s Kit - User’s Guide Page 6 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. -
Page 7: Esd Precaution
Never touch directly on the LPC4357 OEM Board and in general as little as possible on the OEM Base Board. The push-buttons on the OEM Base Board have grounded shields to minimize the effect of ESD. Note that Embedded Artists does not replace boards that have been damaged by ESD. Copyright 2013 © Embedded Artists AB... -

Also, do not apply pressure on the flex cables connecting the LCD/touch screen. These are relatively sensitive and can be damaged if too much pressure is applied to them. Note that Embedded Artists does not replace boards where the LCD has been improperly handled. -
Page 9: Other Products From Embedded Artists
Page 9 Other Products from Embedded Artists Embedded Artists have a broad range of LPC1000/2000/3000/4000 based boards that are very low cost and developed for prototyping / development as well as for OEM applications. Modifications for OEM applications can be done easily, even for modest production volumes. Contact Embedded Artists for further information about design and production services. -

Note that the NAND flash is connected after the memory bus buffers, i.e., on the same side as the LPC4357 OEM Board expansion signals. This is to allow flexibility in NAND flash usage and reduce loading on memory bus that is directly connected to the SDRAM. Copyright 2013 © Embedded Artists AB... -

Page 13: Board Options
The LPC4357 OEM Board contains a small E2PROM, 24AA02E48 from Microchip that can be accessed via I2C. The chip contains a globally unique 48-bit number (EUI-48™) that can be used as Ethernet MAC address. See the 24AA02E48 datasheet for details. Copyright 2013 © Embedded Artists AB... -
Page 14: Oem Base Board Design
The OEM Base Board has been designed to be flexible. Most options can be controlled via jumpers but some options might need soldering. Note that modifications to the board are done at own risk and void all warranties. Copyright 2013 © Embedded Artists AB... -

Note that J4 has gathered all needed signals for expanding the memory bus (16-bit bus expansion). J4 is the expansion connector closest to the board edge. For 32-bit memory bus expansion, J3 is also needed (for the upper 16 bits of the databus). Copyright 2013 © Embedded Artists AB... -

The Serial Expansion Connector is a standardized serial interface connector that is included on many boards from Embedded Artists, including the OEM Base Board. The purpose is to provide a simple expansion connector for smaller expansion modules. Such modules are typically sensors of different kinds and communication modules, but can also be smaller displays. - Page 25 This is pin 13 of J15. It is suggested to short pin 27 and 29 of J3 in order to connect LPC4357 pin PC_11 to this signal – to get GPIO functionality on this pin. Copyright 2013 © Embedded Artists AB...

Remove R163 Figure 35 – Identifying R163 Note that R163 has been removed on all boards shipped out from Embedded Artists after May 15, 2012. Since there is a transition period, and stock at distributors, there is no guarantee that the resistor has been removed on boards delivered after this date. -

All LCD boards supplied from Embedded Artists use the LCD Expansion Connector. There is also an option to connect custom displays via the LCD Expansion Connector, J26. - Page 58 Signal SPI_LCD_DC is typically used for this. Few displays allow for read back of internal control registers via SPI. Only write transfers are typically supported. Copyright 2012 © Embedded Artists AB...

It is strongly advised to read through the list of tests and actions that can be done before contacting Embedded Artists. The different tests can help determine if there is a problem with the board, or not. For return policy, please read Embedded Artists’ General Terms and Conditions http://www.embeddedartists.com/shop/... -

(in case an application is running). It is recommended to download one of the precompiled sample applications from the LPC4357 Developer’s Kit support page on the Embedded Artists web site. How to download is explained in next section. The sample application s_sdram.hex has for example a known current consumption range. The valid range is 650-900m V (which corresponds to 130-180mA). -
