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.
