atmel at88sc0808ca [ summary datasheet ] 5204fs ? crypto ? 1 2 /11 3 1. description the atmel at88sc0808ca member of the atmel cryptomemory ? family is a high - perfor mance se cure memory providing 8 kbit of user memory with advanced security and cryptographic features built in. the user memory is divided into eight 128- byte zones, each of which may be individually set with different security access rights or effectively combine d together to provide space for one to eight data files. the at88sc0808ca features an enhanced command set that allows direct communication with microcontroller hardware two - wi re interface thereby allowing for faster firmware development with reduced code space requirements . 1.1 smart card applications the at88sc0808ca provides high security, low cost, and ease of implementation without the need for a microprocessor operating system. the embedded cryptographic engine provides for dynamic, symmetric - mutual authe ntication between the device and host, as well as performing stream encryption for all data and passwords exchanged between the device and host. up to four unique key sets may be used for these operations. the at88sc0808ca offers the ability to communicate with virtually any smart card reader using the asynchronous t = 0 protocol (gemplus patent) defined in iso 7816 - 3 . 1.2 embedded applications through dynamic, symmetric - mutual authentication, data encryption, and the use of cryptographic message authentication codes (mac), the at88sc0808ca provides a secure place for storage of sensitive information within a system. with its tamper detection circuits, this information rem ains safe even under attack. a two - wire serial interf ace running at speeds up to 1.0 mhz pro vides fast and efficient communications with up to 15 individually addressable devices. the at88sc0808ca is available in industry standard 8 - lead packages with the same familiar pin configuration as atmel at24cxxx serial eeprom devices . note: does not apply to either the tssop or the ultra thin mini - map pinouts figure 1 -1. block diagram random generator authentication, encryption and certification unit eeprom answer to reset data transfer password verification reset block asynchronous iso interface synchronous interface power management v cc gnd scl/clk s d a/io rst

(etu) and is equal to 372/ f . when using the synchronous protocol, data clock ing is done on the positive edge of the clock when writing to the device and on the negative edge of the clock when reading from the device. 3.3 reset (rst) the at88sc0808ca provides an iso 7816 - 3 compliant asynchronous answer -to - reset (atr) sequence. upon act ivation of the reset sequence, the device outputs bytes contained in the 64 - bit atr register. an internal pull - up on the rst input pad allows the device to operate in synchronous mode without bonding rst. the at88sc0808ca does not support an atr sequence i n the synchronous mode of operation . 3.4 serial data (sda/io) the sda/io pin is bidirectional for serial data transfer. this pin is open - drain driven and may be wired with any number of other open - drain or open - collector devices. an external pull - up resistor s hould be connected between sda/io and v cc . the value of this resistor and the system capacitance loading the sda/io bus will determine the rise time of sda/io. this rise ti me will determine the maximum frequency during read operations. low value pull - up re sistors will allow higher frequency operations while drawing higher average power supply current. sda/io information applies to both asynchronous and synchronous protocols .

atmel at88sc0808ca [ summary datasheet ] 5204fs ? crypto ? 1 2 /11 11 9. security fuses there are three fuses on the device that must be blown during the device personalization process. each fuse locks certain portions of the configuration zone as otp (one - time programmable) memory. fuses are designed for the module manufacturer, card manufacturer and card issuer and should be blown in sequence, although all programming of the device and blowing of the fuses may be performed at one final step . 10. communication security modes communications between the device and host operate in three basic modes. standard mode is the default mode for the device after power - up. authentication mode is activated by a successful authentication sequence. encryption mode is activated by a successful encryption activation following a successful authentication . table 10 -1. communication security modes (1) mode configuration data user data passwords data integrity check standard clear clear clear mdc (1) authentication clear clear encrypted mac (1) encryption clear encrypted encrypted mac (1) note: 1. configuration data include viewable areas of the configuration zone except the passwords: ? m dc: modification detection code ? m ac: message authentication code 11. security options 11.1 anti - tearing in the event of a power loss during a write cycle, the integ rity of the device?s stored data is recoverable. this function is optional: the host may choose to activate the anti - tearing function, depending on application requirements. when anti - tearing is active, write commands take longer to execute, since more wri te cycles are required to complete them, and data is limited to a maximum of eight bytes for each write request. data is written first into a buffer zone in eeprom instead of the intended destination address, but with the same access conditions. the data i s then written in the required location. if this second write cycle is interrupted due to a power loss, the device will automatically recover the data from the system buffer zone at the next power - up. non- volatile buffering of the data is done automaticall y by the device. during power - up in applications using anti - tearing , the host is required to perform ack polling in the event that the device needs to carry out the data recovery process . 11.2 write lock if a user zone is configured in the write lock mode, the lowest address byte of an 8 - byte page constitutes a write access byte for the bytes of that page. example: t he write lock byte at $080 controls the bytes from $081 to $087 figure 11 -1. write lock example address $0 $1 $2 $3 $4 $5 $6 $7 $080 11011001 xxxx xxxx xxxx xxxx xxxx x xxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx locked locked locked
atmel at88sc0808ca [ summary datasheet ] 5204fs ? crypto ? 1 2 /11 12 the write lock byte itself may be locked by writing its least significant (rightmost) bit to ?0?. moreover, when write lock mode is activated, the write lock byte can only be programm ed ? that is, bits written to ?0? cannot return to ?1?. in the write lock configuration, write operations are limited to writing only one byte at a time. attempts to write more than one byte will result in writing of just the first byte into the device. 11.3 pa ssword verification passwords may be used to protect read and/or write access of any user zone. when a valid password is presented, it is memorized and active until power is turned off, unless a new password is presented or rst becomes active. there are ei ght password sets that may be used to protect any user zone. only one password is active at a time. presenting the correct write password also grants read access privileges. 11.4 authentication protocol the access to a user zone may be protected by an authentic ation protocol. any one of four keys may be selected to use with a user zone. authentication success is memorized and active as long as the chip is powered, unless a new authentication is initialized or rst becomes active. if the new authentication reques t is not validated, the card loses its previous authentication which must be presented again to gain access. only the latest request is memorized. figure 11 -2. password and authentication operations device (card) card number verify a compute challenge b challenge b verify rpw data checksum (cs) verify wpw verify cs write data host (reader) compute challenge a challenge a verify b read password (rpw) verify cs write password (wpw) data cs authentication read access write access note: authentication and password verification may be attempted at any t ime and in any order. exceeding corresponding authentication or password attempts trial limit renders subsequent authentication or password verification attempts futile.
atmel at88sc0808ca [ summary datasheet ] 5204fs ? crypto ? 1 2 /11 13 11.5 cryptographic message authentication codes at88sc0808ca implements a data validit y check function in the standard, authentication or encryption modes of operation. in the standard mode, data validity check is done through a modification detection code (mdc), in which the host may read an mdc from the device in order to verify that the data sent was received correctly. in authentication and encryption modes, the data validity check becomes more powerful since it provides a bidirectional data integrity check and data origin authentication capability in the form of a message authenticatio n codes (mac). only the host/device that carried out a valid authentication is capable of computing a valid mac. while operating in the authenticatio n or encryption modes, the use of mac is required. for an ingoing command, if the device calculates a mac d ifferent from the mac transmitted by the host, not only is the command abandoned but the security privilege is revoked. a new authentication and/or encryption activation will be required to reactivate the mac . 11.6 encryption the data exchanged between the devi ce and the host during read, write and verify password commands may be encrypted to ensure data confidentiality. the issuer may choose to require encryption for a user zone by settings made in the configuration memory. any one of four keys may be selected for use with a user zone. in this case, activation of the encryption mode is required in order to read/write data in the zone and only encrypted data will be transmitted. even if not required, the host may still elect to activate encr yption provided the pr oper keys are known . 11.7 supervisor mode enabling this feature allows the holder of one specific password to gain full access to all eight password sets, including th e ability to change passwords. 11.8 modify forbidden no write access is allowed in a user zone prot ected with this feature at any time. the user zone must be written during device personalization prior to blowing the security fuses. 11.9 program only for a user zones protected by this feature, data can only be programmed (bits change from a ?1? to a ?0?), bu t not erased (bits change from a ?0? to a ?1?).
