3 Hardware Details
This chapter will give you an overview of the product hardware system
by introducing the CPU and interfaces used on the EDM1070xx.
3.1 CPU Introduction
The EDM1070xx uses NXP’s LPC4357FET256 / LPC1857FET256 – a lowpower high- performance-price-ratio MCU based on ARM-32bit CortexM4/M0 / ARM-32bit Cortex-M3. The LPC4357FET256 is the latest
processor from NXP built with asymmetric dual-core digital signal
controller architecture based on the ARM Cortex-M4 and Cortex-M0
processors, which provides DSP and MCU application developers with a
signal architecture and development environment. The family of the
processors works at 204MHz and integrates on-chip high-speed memory
and abundant peripheral interfaces.
3.2 Interface Introduction
The EDM1070xx provides many different on-board interfaces such as
RS232, Ethernet, USB Host/Device, TF card and LCD interfaces. This
section will give you a brief introduction for each of these interfaces.

Appendix 1: ESD Precautions &
Proper Handling Procedures
Please note that the board comes without any case/box and all
components are exposed. Therefore, extra attention must be paid to
ESD
(electrostatic
discharge)
precautions.
To
effectively
prevent
electrostatic damage, please follow the steps below:

Avoid
carpets
in
cool,
dry
areas.
Leave
development kits in their anti-static packaging
until ready to be installed.

Dissipate static electricity before handling any system components
(development kits) by touching a grounded metal object, such as
the system unit unpainted metal chassis.

If possible, use antistatic devices, such as wrist straps and floor
mats.

Always hold an evaluation board by its edges. Avoid touching the
contacts and components on the board.

Take care when connecting or disconnecting cables. A damaged
cable can cause a short in the electrical circuit.

Prevent damage to the connectors by aligning connector pins
before you connect the cable. Misaligned connector pins can cause
damage to system components at power-on.

When disconnecting a cable, always pull on the cable connector or
strain-relief loop, not on the cable itself.
Warning:
 This is a class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate
measures.
