1. Introduction
The LPCXpresso™ family of boards provides a powerful and flexible development
system for NXP's LPC Cortex®-M family of MCUs. They can be used with a wide range
of development tools, including NXP’s MCUXpresso IDE. The LPCXpresso54608
(OM13092), LPCXpresso54618 (board provided as part of the OM13094 CAN-FD Kit),
LPCXpresso54628 (OM13098), LPCXpresso54018 (OM40003) and LPCXpresso54S018
(LPC54S018-EVK) boards share the same design and have been developed by NXP to
enable evaluation of and prototyping with the LPC546x8/540xx/54S0xx families of MCUs.
There is no functional difference between these boards except the (1) functionality of the
LPC546x8/540xx/54S0xx device installed, and (2) that the LPC54618 board included in
the OM13094 and LPC54S018 board do not include the LCD panel. The
LPCXpresso54018 and LPCXpresso54S018 also use the same board design and
components, but have different booting behavior due to differences in their boot ROMs
and have different internal pull up resistor behavior at reset. All boards use a BGA180
package.
Note that the LPCXpresso54628 board features an LPC54628 device which has a
superset of functionality compared to the LPC54608 and LPC54618. This means code
written for the LPC54608 and LPC54618 can run unchanged on the LPC54628. The
LPC54628 is capable of running at up to 220MHz, but requires a different power library
(from the MCUXpresso SDK) than the other devices in order to run at this clock speed.
The LPCXpresso54018/54S018 boards features and LPC54018 or LPC54S018 MCU
which can operate at up to 180MHz. These MCUs also include CAN-FD support. While
most of the peripherals are identical between LPC540xx, LPC54S0xx and LPC546x8
devices, a different SDK is required for each family.
The schematics show that the board was designed for either 1.8 V or 3.3 V build
configurations, but all production boards are built in the 3.3 V configuration.
