LPCXpresso824-MAX max. current draw

can anyone advise max. current draw for this board

Question relating to:

Last updated: 31 Mar 2019
LPCXpresso824-MAX from NXP is an mbed enabled platform which combines the advantages of the mbed ecosystem and Arduino form factor.

Enzo,

I have opened this issue with NXP and will let you know when i have more information.

Regards,

Enzo,

Thanks for your patience i have received the following reply from NXP

Quote:

Unfortunately we do not perform power consumption measurements for our development platforms, these measurements are only performed to the MCU under specific testing conditions and different frequencies, this information can be found on the chapter 11.4 in the datasheet:

http://cache.nxp.com/documents/data_sheet/LPC82X.pdf

The only testing results we have for the LPCXpresso824-MAX Board are the following, which are the typical low power mode currents at room temperature for an unmodified Max slave board:

  • If you have changed the solder jumper SJ9 on the Max board so that TARGET_RX-P0_18 is connected to LINK_TX, you can connect the terminal emulator to the MBED serial port instead of using a USB-to-UART cable, but the currents you measure will be higher than the following, which were measured at room temperature on one unmodified board.
  • - Sleep mode = 1.276 mA
  • - Deep Sleep mode = 157 uA
  • - Power-down mode = 1.94 uA
  • - Deep Power-down mode = 0.165 uA

In short max current measurements are not supplied, is there any other way i could help you?

I only saw two APIs from power management, is there any more APIs available for following modes?

- Sleep mode = 1.276 mA - Deep Sleep mode = 157 uA - Power-down mode = 1.94 uA - Deep Power-down mode = 0.165 uA
