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.

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 Clock (SCL)
The SCL input is used to clock data into the device on the rising edge and to clock data
out of the device on the falling edge.
Serial Data (SDA)
SDA is a bidirectional pin used to transfer addresses, data or control information into the
device or to transfer data out of the device. The output is open drain, performing a wired
AND function with any number of other open drain or open collector devices. The SDA
bus requires a pull-up resistor to
V
CC
.
Write Protection (WP)
WP switched to
V
SS
allows normal read/write operations.
WP switched to
V
CC
protects the entire EEPROM against changes (hardware write
protection).
Additionally write protection is managed by a protection bit associated to each page.
