ISO 15693-Compliant Secure Memory
General Description
The MAX66140 combines 1024 bits of user EEPROM
with secure hash algorithm (SHA-1) challenge-and-
response authentication (ISO/IEC 10118-3 SHA-1), a
64-bit unique identifier (UID), one 64-bit secret, and a
13.56MHz ISO 15693 RF interface in a single chip. The
memory is organized as 16 blocks of 8 bytes plus three
more blocks—one for the secret and two for data and
control registers. Except for the secret, each block has
a user-readable write-cycle counter. Four adjacent user
EEPROM blocks form a memory page (pages 0 to 3).
The integrated SHA-1 engine provides a Message
Authentication Code (MAC) using data from the
EEPROM of the device and the 64-bit secret to guaran-
tee secure, symmetric authentication for both reading
and writing to the device. Memory protection features
are write protection and EPROM emulation, which the
user can set for each individual memory page. Page 3
can also be read protected for enhanced authentication
strength. The MAX66140 supports all ISO 15693-
defined data rates, modulation indices, subcarrier
modes, the selected state, application family identifier
(AFI), data storage format identifier (DSFID), and the
Option_flag bit for read operations. Memory write
access (except for AFI, DSFID, and the corresponding
lock bytes) is accomplished through custom com-
mands using a write buffer with readback and copy-to-
memory function.
