Serial Programming Bus
Reference and programmable counters can be
programmed by the 3-wire-bus (Clock, Data and Enable).
After setting enable signal to high condition, the data
status is transfered bit by bit on the rising edge of the clock
signal into the shift register, starting with the MSB-bit.
After the Enable signal returns to low condition the
programmed information is loaded according to the
addressbits (last three bits) into the addressed latch.
Additional leading bits are ignored and there is no check
made the 3-wire-bus remains active and the IC can be
programmed.
Data is entered with the most significant bit first. The
leading bits deliver the divider or control information.
The trailing three bits are the address field. There are six
different addresses used. The trailing address bits are
decoded upon the falling edge of the Enable signal. the
internal Loadpulse is beginning with the falling edge of
the Enable signal and ending with the falling edge of the
Clock signal. Therefore a minimum holdtime
clock-enable tHCE is required.

To operate the software power down mode the following condition must be set: HXP = 0; power up and power down
will be set by SPDX = 1 (on) and SPDX = 0 (off).
To operate the hardware power down mode the following condition must be set: HXP = 1; SPDX = 1; power up and
power down will be set by high and low state at the hardware power down pins 9/14.
High current of charge pump synthesizer 1 is active when 5I = 1 and if 5IP = 1 the charge pump current control input
pin 1 is in high state.

Ozone Depleting Substances Policy Statement
It is the policy of TEMIC TELEFUNKEN microelectronic GmbH to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems
with respect to their impact on the health and safety of our employees and the public, as well as their impact on
the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as
ozone depleting substances ( ODSs).
The Montreal Protocol ( 1987) and its London Amendments ( 1990) intend to severely restrict the use of ODSs and
forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban
on these substances.
TEMIC TELEFUNKEN microelectronic GmbH semiconductor division has been able to use its policy of
continuous improvements to eliminate the use of ODSs listed in the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively
2 . Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency ( EPA) in the USA
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C ( transitional substances ) respectively.
TEMIC can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain
such substances.
We reserve the right to make changes to improve technical design and may do so without further notice.
Parameters can vary in different applications. All operating parameters must be validated for each customer
application by the customer. Should the buyer use TEMIC products for any unintended or unauthorized
application, the buyer shall indemnify TEMIC against all claims, costs, damages, and expenses, arising out of,
directly or indirectly, any claim of personal damage, injury or death associated with such unintended or
unauthorized use.
