Page 3: Introduction
UM11057 NXP Semiconductors User Manual 1. Introduction The LPCXpresso-MAX family of boards provides a powerful and flexible development system for NXP's low end Cortex-M0+ MCUs. They can be used with a range of development tools, including the MCUXpresso IDE toolchain. The LPCXpresso845MAX board is developed by NXP to enable evaluation of and prototyping with the LPC84x family of MCUs. -

Page 8: Debug Probe
UM11057 NXP Semiconductors User Manual 4. Debug Probe The on-board LPC11U35 provides CMSIS-DAP debug probe functionality, plus a virtual comm port (VCOM) capability via PIO1_16 and PIO1_17 of the LPC845 target. This functionality bridges the LPC845 serial port via USB, so that PC applications such as TeraTerm and PuTTY can communicate directly with the target. -

Page 10: Pmod Connector
UM11057 NXP Semiconductors User Manual Note that the default ports for ISP boot are connected to J1 (I2C) J2 (USART). The Arduino power connector (J5) pin 2 (IOREF) and pin 3 (+3V3) are routed to the 3.3V regulator output. J5 pin 5 (5V) is routed to the 5V supply from USB. J5 pin 8 (VIN) can also be connected to this 5V supply by closing solder jumper SJ16 (this connection is required by some Arduino shields). -
Page 11: Power Measurement
UM11057 NXP Semiconductors User Manual 6. Power measurement JP2 is provided to enable supply current to the LPC845 to be measured by placing an ammeter in line with JP2 pins. By default this jumper is bypassed by solder jumper (SJ6). -
Page 12: Speaker Driver
UM11057 NXP Semiconductors User Manual 7.4 Speaker driver The LPC845 DACOUT output PIO0_29 is route to an IS31AP4991 speaker driver (see Integrated Silicon Solutions web site for datasheet). This device can drive 8 to 32 ohm speakers; a 32 ohm speaker is supplied with the board and resistors have been selected to provide a reasonable volume level for musical tones. -
