Dear Customer:
Please be advised that ZiLOG is in the process of changing the current Z80S183/Z80L183 die
revision "B" for the Mixed Signal 180. The new Z80S183/Z80L183 die revision “C” is fully
compatible with the existing Z80S183/Z80L183 with the exception of the following improvements.
1. Improved Sleep Mode current of less than 1.7 mA @ 5V less than 700µA @ 3V.
2. All modes of the Watch Dog Timer are functional.
3. The CPU ID Register at location 3Dh is changed from 00h to 02h to reflect the new die.
All Z80S183/Z80L183 have a date code in the lower left corner of the package and follow the
yyww convention, where yy is the year and ww is the week. The improved die will be
stamped date code later than 0025. If you wish to receive qualification samples of the new
product, contact the ZiLOG field sales office serving your area.
Sincerely,
Mike Burgdorf
Director
