HB28H016/D032/B064/B128MM2
Access Time
Parameter
Synchronous access delay cycles
Synchronous access delay
Asynchronous access delay
Memory access time
Note:
In the CSD are two fields to code the asynchronous and the synchronous access delay time:
• TAAC, asynchronous access delay
• NSAC, maximum number of cycles for receiving and interpreting of a command frame
The value for the CSD field NSAC is calculated from N
and rounding up to the next integer:
• NSAC = 0x01
The value for the CSD field TAAC is 1 ms:
• TAAC = 0x0E
For more details on NSAC and TAAC CSD-entries refer to Chapter “Card Specific Data (CSD)”.

Number Representations
• decimal numbers: 1234, no special characters
• hexadecimal numbers: 0xAB, leading 0x, each digit represents 4 bits.
• binary numbers (single bit): ‘0’.
• binary number (unsigned bit vector): “100100”.
• 1k is equal to 1024.
• 1M is equal to 1k * 1k, except the card capacity. In the card capacity, 1M is equal to 10
• 1G is equal to 1M * 1k
