8.9 Get_UID() command
Command code = 0Bh
On receiving the Get_UID command, the SRI512 returns its 8 UID bytes. UID bytes are
transmitted with the least significant byte first, and each byte is transmitted with the least
significant bit first.
The SRI512 must have received a Select() command and be switched to Selected state
before any Get_UID() command can be accepted. All Get_UID() commands sent to the
SRI512 before a Select() command is issued, are ignored.

Request parameter:
● No parameter
Figure 48. Get_UID response format
Response parameters:
● UID 0: Less significant UID byte
● UID 1 to UID 6: UID bytes
● UID 7: Most significant UID byte.

Unique Identifier (UID)
Members of the SRI512 family are uniquely identified by a 64-bit Unique Identifier (UID).
This is used for addressing each SRI512 device uniquely after the anticollision loop. The
UID complies with ISO/IEC 15963 and ISO/IEC 7816-6. It is a read-only code, and
comprises (as summarized in Figure 49):
● an 8-bit prefix, with the most significant bits set to D0h
● an 8-bit IC manufacturer code (ISO/IEC 7816-6/AM1) set to 02h (for
STMicroelectronics)
● a 6-bit IC code set to 00 0110b = 6d for SRI512
● a 42-bit unique serial number

8.10 Power-on state
After power-on, the SRI512 is in the following state:
● It is in the low-power state.
● It is in Ready state.
● It shows highest impedance with respect to the reader antenna field.
● It will not respond to any command except Initiate().

SRI512 Maximum rating
Doc ID 13263 Rev 5 39/47
9 Maximum rating
Stressing the device above the rating listed in the absolute maximum ratings table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
