Output Parameters Name Size Notes Success 1 Upon successful execution, a value of zero will be returned by AT88SA102S. Atmel AT88SA102S [DATASHEET] 8584H−CRYPTO−9/2012 19 6.6 PauseLong Forces the chip into the pause state until the watchdog timer expires, after which it will automatically enter into the sleep state. During execution of this command and while in the pause state the chip will ignore all activity on the IO signal. This command is used to prevent bus conflicts in a system that also includes other AT88SA102S chips or a CryptoAuthentication host chip sharing the same signal wire. Table 6-13. Input Parameters Name Size Notes Opcode PAUSELONG 1 0x01 Param1 Selector 1 Which chip to put into the pause state, 0x00 for all AT88SA102S chips Param2 Zero 2 Must be 0x0000 Data Ignored 0 The Selector parameter provides a mechanism to select which device will pause if there are multiple devices on the bus: • • If the selector parameter is 0x00, then every AT88SA102S chip receiving this command will go into the pause state and no chip will return a success code. If any of the bits of the selector parameter are set, then the chip will read the values of Fuse[84-87] and go into the pause state only if those fuse values match the least significant 4-bits of the selector parameter. If the chip does not go into the pause state, it returns an error code of 0x0F. Otherwise it goes into the pause state and never returns any code.

It is expected that an external pullup resistor will be provided to pull this signal up to VCC for proper communications. When the chip is not in use this pin can be pulled to either VCC or GND. 8 2 VCC Power supply, 2.7 – 5.25 V. This pin should be bypassed with a high quality 0.1µF capacitor close to this pin with a short trace to GND Additional applications information at www.atmel.com 4 3 GND Connect to system ground 1,2,3,6,7 -- NC Not connected Atmel AT88SA102S [DATASHEET] 8584H−CRYPTO−9/2012 21 Packaging Information 3TS1 – 3-lead Shrink SOT 3 GND E1 CL E Signal SDA VCC 1 L1 8. 2 e1 End View Top View b A2 SEATING PLANE e A A1 D Side View Notes: 1. Dimension D does not include mold flash, protrusions or gate burrs. Mold flash, protrusions or gate burrs shall not exceed 0.25mm per end. Dimension E1 does not include interlead flash or protrusion. Interlead flash or protrusion shall not exceed 0.25mm per side. 2. The package top may be smaller than the package bottom. Dimensions D and E1 are determined at the outermost extremes of the plastic body exclusive of mold flash, tie bar burrs, gate burrs and interlead flash, but including any mismatch between the top and bottom of the plastic body. 3. These dimensions apply to the flat section of the lead between 0.08 mm and 0.15mm from the lead tip. This drawing is for general information only.
