TMS320LC203: Help Identifying Date Code on TMS320LC203PZA Marking

Part Number: TMS320LC203

Tool/software:

Hi TI team,

I need your help verifying the date code (DC) from a batch of TMS320LC203PZA chips.
Please see the attached photo for reference.

The second line of the marking is:
EA-87A704W

Can you confirm if "704" indicates 2007, week 04 as the manufacturing date?

If not, could you explain the correct interpretation of the marking format?

Thank you in advance for your support.

Best regards,

Angela An
