UPD77110 Datasheet (NEC) - 16-BIT FIXED-POINT DIGITAL SIGNAL PROCESSORS

UPD77110, 16-BIT FIXED-POINT DIGITAL SIGNAL PROCESSORS

The µPD77110, 77111, and 77112 are 16-bit fixed-point digital signal processors (DSPs).

Compared with the µPD77016 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.
