Secure Memory
General Description
The MAX66040 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 RF interface (ISO/IEC 14443 Type B, Parts 2-
4) 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 guarantee secure, symmetric authentica-
tion 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. Memory access is
accomplished through the block transmission protocol
(ISO/IEC 14443-4), where requests and responses are
exchanged through I-blocks once a device is in the
ACTIVE state. The data rate can be as high as
847.5kbps. The reader must support a frame size of 26
bytes. The device supports an application family identi-
fier (AFI) and a card identifier (CID). ISO/IEC 14443
functions not supported are chaining, frame-waiting
time extension, and power indication.
