µPD77210, 77213
16-BIT FIXED-POINT DIGITAL SIGNAL PROCESSOR
The µPD77210 and 77213 are 16-bit fixed-point digital signal processors (DSP).
Compared with the existing members of the µPD77111 Family, the µPD77210 Family consumes less power and is
ideal for battery-driven mobile terminal applications such as PDAs and cellular telephones. The µP77210 Family is
DSP is also compatible with the µPD77111 Family at the binary level.
The µPD77210 Family consists of the µPD77210 and 77213. Unless otherwise specified, the µPD77210 Family
refers to the entire family. If there are some differences in function or operation among family products, they are
described under their respective names.
The functions of the µPD77210 Family are described in detail in the following user’s manuals. Refer to these
manuals when designing your system.
