Part Number: TMS320F28375D

Hi,

Customer would like to know a way to recognize a package type (BGA or QFP) by S/W, e.g. a register access.

Yoshita-san,

Yes the PIN_COUNT field(bits 10-8) in the PARTIDL register has the pin information for the device. This can be found in the device TRM here: http://www.ti.com/lit/spruhm8 page 262. This should also be a documented field in the driver LIB. Note this register is only accessible through CPU1 on a dual core device.

This register is located at 0x5D0008 with bit description below:

Best,
Matthew

Hi Matthew,

Let me confirm one thing just in case.
Customer is worried about the change of meaning of PIN_COUNT for 5, 6 and 7 in the future.
Is the current fixed value (meaning) unchanged in the future?

Yoshita-san,
The current value is fixed for the F2837xD/F2837xS/F2807x devices. If this bit field is supported on a different device(like F28004x) then the bits could have different meanings. However, the PARTNO bitfield in the PARTIDH register(offset 0xA) would tell the FW the family the device belongs to to limit that scope.

Best,
Matthew
