UPD77P25 - Digital Signal Processor

This page provides the datasheet information for the UPD77P25, a member of the UPD77C25 Digital Signal Processor family.

Datasheet Summary

Description

The uP077C25/uP077P25 signal processing interface (SPI) chips are significant upgrades to the uP07720 - the original member of NEC's family of digital signal processors.

Oesignated the "SPI PLUS" (SPI+), these chips execute instructions twice as fast as the 7720/77C20.

Features

  • ) that can occur during one 122 ns instruction cycle. (On competitive OSP chips such operations raquire separata instructions). For a typical DSP filter.
