Preface
Thank you for choosing Toshiba semiconductor products. This is the 2000 edition of the databook for
the TMPR3911/12 32-bit TX System RISC microprocessor.
This databook is designed to be easily understood by engineers who are designing the Toshiba
TMPR3911/12 RISC microprocessor into their products for the first time. No special knowledge of this
device is assumed – the contents includes basic information about the microprocessor and the
application fields in which it is used. In addition, complete technical specifications are given,
facilitating incorporation of the device into any given user application.
Toshiba are continually updating technical publications. Any comments and suggestions regarding any
Toshiba document are most welcome and will be taken into account when subsequent editions are
prepared. To receive updates to the information in this databook, or for additional information about the
products described in it, please contact your nearest Toshiba office or authorized Toshiba dealer.
