... VCC RST Description The AT88SC153 provides 2,048 bits of serial EEPROM memory organized as one configuration zone of 64 bytes and three user zones of 64 bytes each. This device is optimized as a “secure memory” for multiapplication smart card markets, secure iden- tification for electronic data transfer, or components in a system without the requirement of an internal microprocessor ...

... Memory Access AT88SC153 2 The embedded authentication protocol allows the memory and the host to authenticate each other. When this device is used with a host that incorporates a microcontroller (e.g., AT89C51, AT89C2051, AT90S1200), the system provides an “anti-wiretapping” configuration. The device and the host exchange “challenges” issued from a random generator and verify their values through a specific cryptographic function included in each part ...

... When the RST input is pulsed high, the device will output the data programmed into the 32-bit answer-to-reset register. All password and authentication access will be reset. Following a reset, device authentication and password verification sequences must be presented to re-establish user access. AT88SC153 Authentication Random Unit ...

... UAT Programmable Chip Select (CS0–CS3): The four most significant bits (b4–b7) of every command comprise the chip select address. All AT88SC153 devices will respond to the default chip select address of $B (1011). Each device will also respond to a second chip select address programmed into CS0–CS3 of the device configuration register. By pro- gramming each device to a unique chip select address possible to connect devices on the same serial data bus ...

Checksum Authentication Register User Zones Security Operations Write Lock AT88SC153 8 Unlimited Authentication Trials (UAT): If enabled (UAT = “0”), the AAC is disabled, allowing an unlimited number of authentication attempts. The PACs are not affected by the UAT bit. Unlimited Checksum Reads (UCR): If enabled (UCR = “0”), the device will allow an unlimited number of checksums without requiring a new authentication. Supervisor Mode Enable (SME): If enabled (SME = “ ...

... The current password is memorized and active until power is turned off, unless a new password is presented or RST becomes active. Only one password is active at a time. The AT88SC153 requires that the Verify Password command be transmitted twice in sequence to successfully verify a write or read password. (This two-pass method of password verification was implemented in the AT88SC153 to protect the device from attacks on the password security system ...

... Answer-to-reset Verify Password AT88SC153 12 If RST is high during SCL clock pulse, the reset operation occurs according to the ISO 7816-10 synchronous answer-to-reset. The four bytes of the answer-to-reset register are transmitted least significant bit first, on the 32 clock pulses provided on SCL. The values programmed by Atmel are shown in Figure 8 below. ...

... SCL-low time periods (Figure 13 on page 14). Data changes during SCL-high time periods will indicate a start or stop condition as defined below. A high-to-low transition of SDA with SCL high is a start condition that must precede any other command (Figure 12 on page 14). AT88SC153 Q1(1) Q1(7) 13 ...

... The device sends a “0” to acknowledge that it has received each byte. This happens during the ninth clock cycle. The AT88SC153 features a low-power standby mode that is enabled upon power-up and after the receipt of the stop bit and the completion of any internal operations. ...
