DESCRIPTION
The
μ
PD77110, 77111, and 77112 are 16-bit fixed-point digital signal processors (DSPs).
Compared with the
μ
PD77016 family, these DSPs have improved power consumption and are ideal for battery-
powered mobile terminals such as PDAs and cellular phones.
Both mask ROM and RAM models are available.
For details of the functions of these DSPs, refer to the following User’s Manuals:
