Memory and protocol values describe the IC. Actual read performance depends on the finished antenna, enclosure, reader and operating environment.
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.
Integration and qualification
Validate the modulation, bit rate and identifier format with the installed low frequency reader. NFC phones do not read 125 kHz credentials. For programmed formats, agree a sample identifier and confirm how the host system interprets it.
Check key ring attachment, handling and scan orientation. Assess the fob alongside keys and other metal objects under normal use.
Approve an encoded sample in the finished application before volume production. Define acceptance criteria for identification, memory access, printed data and repeated operation.
Define your production requirement.
