    UM11158 NXP Semiconductors LPCXpresso55S69 Development Board 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 LPCXpresso55S69 board (order code LPC55S69-EVK) is the evaluation and development platform for the LPC556x family of MCUs.

    UM11158 NXP Semiconductors LPCXpresso55S69 Development Board The Link2 Debug Probe on the board will have been programmed with CMSIS-DSP firmware during manufacture, but can also be updated with J-link OB for LPC-Link2. To start the board with this firmware running, ensure J4 is not installed as power is connected, so the Link2 Debug Probe boots from internal flash.

    UM11158 NXP Semiconductors LPCXpresso55S69 Development Board 4. On-board (Link2) Debug probe This section describes the features provided by the on-board Link2 Debug Probe, including how to use this to debug an exernal target. The Link2 Debug Probe is implemented using an LPC432x MCU (circuit reference U2), which provides a high speed USB port interface to the host computer that runs the development tools.

    UM11158 NXP Semiconductors LPCXpresso55S69 Development Board 4.1 Link2 boot LED LED DS2 is the Link2 MCU BOOT0_LED indicator. This LED reflects the state of Link2 MCU pin P1_1. When the boot process fails, DS2 will toggle at a 1 Hz rate for 60 seconds.

  • Page 14: Board Power

    UM11158 NXP Semiconductors LPCXpresso55S69 Development Board 5. Board Power The LPCXpresso55S69 board requires +5V input to power the on-board voltage low dropout linear regulators, of which there are 3, all available from Torex Semiconductor. The Link2 Debug probe has a 2.5V regulator (U10) which draws power from USB connector P6 (“Debug Link”) only.

  • Page 15: Usart Header

    UM11158 NXP Semiconductors LPCXpresso55S69 Development Board The Board can only be configured to support one of these ports as a host at a time (this is a limitation of the board, not the LPC55S69). When either port is used as a host, power must be supplied to the board via the +5V power only micro B USB port.

    UM11158 NXP Semiconductors LPCXpresso55S69 Development Board SDIO port 1 of the LPC55S69 is routed to the expansion connector to provide access to this interface. Note that the power enable signal used for this SDIO interface is not one of the port pins that supports in SD1_POWER_EN function; this because all port pins that support this function are required for other features of the board.
