DESCRIPTION
The members of the ST1335D/36D/55D family are
principally designed for use in prepaid Phonecard
applications. Each is a 272-bit EEPROM device,
with associated security logic and special fuses to
control memory access. The memory is arranged
as a matrix of 34 x 8 cells, accessed in a serial bit-
wise fashion for reading and programming, and in
a byte-wise fashion for internal erasing. An on-chip

The anti-tearing mechanism guards against mis-
counts occurring when the card is prematurely
extracted, while an operation is underway, in an
open reader.

MODES
The device works in two distinct modes of
operation:
– Issuer Mode: for the card manufacturer.
allowing custom data to be written to the device,
to initialize it before release to the end user.

– User Mode: for the end user of the card, with
restricted, and controlled access to the device.
Before delivery, from ST to the card issuer, the
device is placed in the Issuer Mode. This operation
is performed by blowing the “test fuse”.

OPTIONS
Three options are available when ordering the
device:
address counter provides an internal address
space of up to 512 bits.
– The
anti-tearing
mechanism
can
be
Each member of the ST1335D/36D/55D family
has an identification data area, unit-counters (with
an anti-tearing mechanism for reliable usage in
open readers), a post validation certificate, an
issuer area (ST1336D) or an authentication secret
key area (ST1335D/55D), and a user area. This is
summarized in Figure 3.
The validation certificate allows the recognition of
the device by the appropriate security module.
When the 8 times reloadable option is activated,
the certificate and the reload counter (address 64d
to 71d) can be used to allow the recognition of the
circuit by the appropriate security module. This will
allow the development of a reloadable card as the
certificate value is refreshed each time the reload
counter is incremented.
disconnected. In this case, the anti-tearing flag
area from bit 288d to bit 319d is unused (Figure
3).
– The user area, from bit 320d to bit 375d, can be
defined as “not erasable” in the User Mode.
– The reload mechanism can be activated. In this
case, erasing a bit in the reload counter
refreshes the certificate (CER). At this time, the
certificate can be programmed with a new
value.
