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.
