AS39513 − Detailed Description

OSCTRIM[7:0] – Real-time oscillator trim setting. This value is

mapped directly to osc_trim_o[7:0]. See the description of the

Real-Time Oscillator for more information.

ROSTRIM[7:0] – High-speed ring oscillator trim setting. This

value is mapped directly to ros_trim_o[4:0]. See the description

of the High-Speed Oscillator for more information.

LKALL – Lock all memory. If set, this bit will prevent all

Measurement EEPROM from being written directly through

RFID commands. Logging events will still be able to write to the

Measurement memory.

0 = Lock setting depends on individual block lock bits.

1 = Lock all EEPROM Measurement areas from RFID writes.

V0TRIM[4:0] – Main voltage trim setting for the trimmed

reference.

TSENTRIM[3:0] – Temperature sensor bandgap slope trim. This

value is mapped directly to tsen_trim_o[3:0]. See the

description of the Temperature Sensor for more information.

DSF_LK – Lock the data storage format identifier. This bit can

be set through the Lock DSFID command.

0 = The Write DSFID command can change the DSFID value.

1 = The Write DSFID command cannot change the DSFID value.

AFI_LK – Lock the application family identifier. This bit can be

set through the Lock AFI command.

0 = The Write AFI command can change the AFI value.

1 = The Write AFI command cannot change the AFI value.

CHIPREV[7:0] – The chip revision identifier. This value can be

read through the Get System Info RFID command.

8’h11 = AS39513 v2.0.

UID[63:0] – The unique RFID identifier. This value can be read

through the Get System Info RFID command.
