Hello,
- I-TCM is the Instruction Tightly Coupled Memory and it contains the interrupt handlers and a few library APIs.
- FX2LP has got a fixed memory map unlike FX3 and it can be seen from the EZ-USB TRM.

Hello,
The .map file that is generated as part of the project build contains the memory configuration for the FX3 firmware.

Hello,
Please view below the memory allotment for your firmware file.
Code memory size - 180kB
Data memory size - 32kB
This information is present as part of the *.ld file that comes with the FX3 SDK in the following path.
C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\fw_build\fx3_fw
