UPD77112 - 16-BIT FIXED-POINT DIGITAL SIGNAL PROCESSORS

Datasheet Summary

Description

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 batterypowered mobile terminals such as PDAs and cellular phones.

Both mask ROM and RAM models are available.

Features

  • z Instruction cycle (operating clock) µPD77110 : 15.3 ns MIN (65 MHz MAX) 13.3 ns MIN (75 MHz MAX) (Operating voltage and ambient temperature are limited. ) µPD77111 : 13.3 ns MIN (75 MHz MAX) µPD77112 : 13.3 ns MIN (75 MHz MAX) z Memory.
  • Internal instruction memory µPD77110 : RAM 35.5K words × 32 bits µPD77111 : RAM 1K words × 32 bits Mask ROM 31.75K words × 32 bits µPD77112 : RAM 1K words × 32 bits Mask ROM 31.75K words × 32 bits.
  • Data memory µPD77110 : RAM 24K words × 16.
