ADUA1462 Program and Data memory size

Hi,

 

Please let me confirm memory size of the ADAU1462.

 

On the ADI web page and data sheet ( rev.A ), we can find below. Is it correct values ?

http://www.analog.com/media/en/technical-documentation/data-sheets/ADAU1462-1466.pdf 

 

  Page 3 Table1. Product Selection Table
  ADAU1462 Data memory 48(KWords) Prgram Memory 16(Kwords)

 


But on the data sheet ( rev.A ), we can find different values.
The table 58 shows that ADAU1462's program memory size is 8 Kwords
It seems that the Figure 82 for the ADAU1466 illustrates the ADAU1462, but the program memory size is 8K words
It seems that the Figure 83 for the ADAU1462 illustrates the ADAU1466.

 

  Page 88 Table 58. ADAU1462 Memory Map
  Address Range         Length
  0xC000 to 0xCFFF      4096 words
  0xC000 to 0xCFFF      4096 words

On the other hands, on the Sigma Studio ver3.15.2 beta,
when putting the ADAU1462 in the project and build the schematic, we can see following messages.
The data program size is 40 Kwors.
