DESCRIPTION The members of the ST133x family are principally designed for use in prepaid telephone card applications. They consist of 272 bits of EEPROM, with associated hard-wired 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 program2/3
ming, and in a byte-wise fashion for internal erasing. An on-chip address counter provides an internal address space of up to 512 bits. Each chip has an identification data area, counters (with an anti-tearing mechanism for reliable usage in open readers), a post validation certificate, an issuer area (ST1331/36) or an authentication secret key area (ST1333/35), and a user area. The
ST1331, ST1333, ST1335, ST1336
validation certificate allows the recognition of the circuit by the appropriate security module. The anti-tearing mechanism guards against extra, spurious count signals being executed when the card is unexpectedly extracted, while an operation is underway, in an open reader. Each device works in two distinct configurations: - Issuer Configuration: for the card manufacturer. Customised data can be written to the chip, to initialise it before release to the end user - User Configuration: for the end user of the card, with restricted access to the chip Three options can be chosen on ordering: - The anti-tearing mechanism can be disconnected. In this case, the anti-tearing flag area from bit 288d to bit 319d is unused (see Figure 2 on the previous page). - The user area, from bit 320d to bit 375d, can be defined as "not erasable" in the User Configuration. - The reload mechanism can be activated. In this case, erasing a bit in the reload counter refreshes the certificate (CER). EXTERNAL COMMANDS The device recognises four commands issued via the external pins: - RESET: to reset the internal address register to 000d - READ: to increment the internal address register and read the data bit at the new address - COMPARE: to allow comparison of the presented code against the internal transport code - PROGRAM: to program the bit at the current address These commands are encoded either as a five- or six-contact protocol, according to the device type: - Five-contact protocol used by ST1335 and ST1336, using VCC, GND, I/O, CLK, RST - Six-contact protocol used by ST1331 and ST1333, using the additional B contact.
