Packing
Please use the recycling operators known to you. We can also help you – get in touch with your nearest sales office. By agreement we will
take packing material back, if it is sorted. You must bear the costs of transport.
For packing material that is returned to us unsorted or which we are not obliged to accept, we shall have to invoice you for any costs in-
curred.
Components used in life-support devices or systems must be expressly authorized for such purpose!

1 A critical component is a component used in a life-support device or system whose failure can reasonably be expected to cause the
failure of that life-support device or system, or to affect its safety or effectiveness of that device or system.
2 Life support devices or systems are intended (a) to be implanted in the human body, or (b) to support and/or maintain and sustain hu-
man life. If they fail, it is reasonable to assume that the health of the user may be endangered.

Pin Description
Serial Input (SI)
The SI pin is an input and used to clock all instructions, byte addresses and data into the
device. Input data is latched on the rising edge of the serial clock.
Serial Output (SO)
The SO pin is an output and used to shift data out of the device. Data is clocked out by
the falling edge of the serial clock.
Serial Clock (SCK)
The SCK pin is an input and used to synchronize the communication between the master
and the EEPROM.
Chip Select (CS)
The CS pin is an input and used to enable or disable the device. When the CS pin is low,
the device is enabled. When the CS pin is high, the device is disabled and, if no internal
programming cycle is in process, forced into the standby mode.
After power up, a high-to-low transition of the CS pin is required prior to the start of any
operation.
A low-to-high transition of the CS pin after a valid write or erase command starts an
internal programming cycle. Independent of the CS pin an already started programming
cycle will be finished and then the device forced into the standby mode. When the device
is deselected, SO goes to the high impedance state, allowing multiple parts to share the
same SPI bus.
