LPCXpresso55S69/55S28 Development Boards
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, Keil uVISION and IAR Embedded
Workbench. The LPCXpresso55S69 board (order code LPC55S69-EVK) and
LPCXpresso55S28 board (order code LPC55S28-EVK) are the evaluation and
development platforms for the LPC55S6x and LPC55S2x/LPC552x families of MCUs
respectively.
See https://www.nxp.com/demoboard/LPC55S69-EVK or
https://www.nxp.com/demoboard/LPC55S69-EVK for more information on these boards,
including tutorial videos, development software and board hardware design files. Both
board designs are identical except for the LPC target MCU fitted; the information in this
manual applies to both board types unless otherwise noted. The abbreviation LPC55Sxx
is used to collectively refer to the LPC55S69 or LPC55S28 device on these boards. Note:
the schematics for this board indicate components that are not installed by default
with a red cross.
The LPCXpresso55S69 and LPCXpresso55S28 boards include the following features:
• LPC55S69 Dual Cortex-M33 core processor or LPC55S28 Cortex-M33 processor
