TR83100CF

The TR83100CF is one kind of voice storage controller,it is designed in advanced CMOS technology for use in voice storage applications.Incorporating all blocks required in the digitization,storage and playback of voice signals, TR83100CF interfaces directly to a microphone for voice input and a speaker for voice playback with minimal external components.An on-board compression and decompression engine works in conjuction with a memory controller to allow the voice data to be stored in parallel flash memory.A sophisticated message management scheme allows a voice recorder to be implemented by simply connecting suitable memory.

Features of the TR83100CF are:(1)single chip voice controller;(2)message management;(3)flash memory interface-parallel;(4)intelligent power management;(5)over 14 minutes of speech storage in 8 Mbit flash;(6)ADPCM compression/decompression;(7)provides audio and LED feedback to user;(8)customizable.It can be used in voice memo recorders,dictaphones;automatic call distribution system;cell phone answering machines and electronic information tags;electronic organizers.

The absolute maximum ratings of the TR83100CF can be summarized as:(1)supply voltage:-0.5 to 6.5 V;(2)input voltage:-0.5 to Vdd+0.5 V;(3)output voltage:-0.5 to Vdd+0.5 V;(4)storage temperature:-40 to 125.But the recommender DC operating conditions of it are:(1)supply voltage(VDD):4.5 to 5.5 V;(2)supply voltage(AVD):4.75 to 5.25 V;(3)ambient temperature:0 to 70.
