CryptoAuthentication Host Security Chip

Atmel Corporation 

4.7.

PauseShort

Forces the chip into a busy mode for a period of t PAUSE. During execution of this command the chip will ignore all

activity on the IO signal. This command is used to prevent bus conflicts in a system that also includes one or more

AT88SA100S or AT88SA102S client chips sharing the same signal wire.

Notes

1

After a delay of t PAUSE, the AT88SA10HSS will return a value of 0 in response to a

transmit flag.

5. Pinout

There are three pins on the chip.

Name

Description

1

Signal

IO channel to the system, open drain output. It is expected that an external pull-up 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 VSS.

2

VCC

Power supply, 2.5 – 5.5V. This pin should be bypassed with a high quality 0.1μF capacitor

close to this pin with a short trace to VSS. Refer to Applications Notes on Atmel’s website for

more details.

3

VSS

Connect to system ground.
