The numerical specifications here refer to ATA5577C. They do not establish that every product described as T5577 uses the same silicon revision. Confirm the complete IC part number in the approved order.
Select the modulation, data rate and block configuration for the installed reader. Password mode and locking are not equivalent to cryptographic challenge response authentication.
Reserve the password block when calculating application data capacity. Verify programmed data before applying irreversible block locks.
