IWR1443BOOST: used pins for connecting MSP432 to IWR1443boost

feng tang

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1443

Anyone know the used pins for connecting MSP432 to IWR1443boost with ES3 chip in level sensing demo? We try to reduce the connector size to minimize the used pins.

Thanks,

Hello Feng,

I am updating the Altium schematic from TIDEP91, it will be available tomorrow.

I am including a general IO block diagram for now.

Hi Joe,

Once you update the schematic, could you create a PDF file of it? We cannot read VSD file, we use Orcad.

Thanks,

Hello Feng,

The zip file contains the EXCEL comparing the BP/LP connections IWR1443BOOST and the MSP432R401 EVM. There is a PDF of the Altium schematic, the schematic sheets, the Altium project file.

Hi Joe,

Are you able to create a PDF file for the ES3 schematic? I am not able to open the SCHDOC files, The PDF file that in the zip file is from 2016, and it not for the ES3 EVM board.

Thanks,

Hello Feng,

Your initial question was about connectivity for TIDEP 0091, this is in the ZIP file I sent yesterday, there is a PDF of this combined schematic, Altium schematic and project files, and an EXCEL of the connectivity for the MSP432R401 and IWR1443 BOOST EVM.

The IWr1443 ES2 vs new ES3 device can use the same schematic. The orderable part number will change next month.

The hardware for RevB(Altium) and RevA(Cadence) is in the new updated link: (same zip files new content)

Hi Joe,
Thanks! I noticed you update the schematic through ES1 schematic.
Can you explain what these pins are exactly do? (what kind of the control and the communication that they do?)
AR_CSn1
AR_MOSI1
AR_MISO1
MCU_SOP0
MCU_SOP2
AR_HOSTINST1
If we remove the temperature sensor, can we remove ar_SCL and AR_SDA?

Thanks,

Hello Feng,
AR_CS1, AR_MOSI1, AR_MISO1, AR_SPICLK, AR_CSn1, AR_HOSTINST1 are part of the 4 wire SPI slave, and Host Interrupt (from Slave )
interface, these are needed for higher speed Host Processor communication, and are used in TIDEP-91.

AR_SCL and AR_SDA are not needed at the mmwave IWR1443, they are needed for PMIC programming from MSP430 Host. You need pullups from appropriate 3.3v supply.

MCU_SOP0, MCU_SOP2 - can be reduced to just MCU_SOP2, for remote QSPI flashing, with Control UART Tx, Control UART Rx, and
AR_NRESET force from Host Processor.

You can remove the temperature probe.

Hi Joe,
Thanks! Do you mean if we use sop2 jump for flash, then we do not need MCU_SOP2? I do not see you mark AR_SPICLK for using in TIDEP-91, can I remove this from the connector pin and tie to a pull up?

Thanks,

Hello Feng,

You can either use MCU_SOP2 as a signal, or directly connect to SOP2. SOP0=1 - for Flashing mode.

SOP2=0 - functional

SOP2=1 - flashing

SPI needs 5 signals

SPI_CLK (driven from MSP430)

SPI_CSn (driven from MSP430)

SPI_MISO (driven from IWr1443)

SPI_MOSI (driven from MSP430)

HOST_INTERRUPT (driven from IWR1443)

IWR1443

MSP432
