TEA7091
DESCRIPTION
The TEA7091 is a Telephone set Analog Front
End (TAFE) interface intended for use in conjunc-
tion with a microcontroller.
In this configuration the TEA7091 provides a
worldwide mid-range telephone set with loudhear-
ing on board and melody ringer on loudspeaker.
Repertory dialer (memory on MCU) and various
features (HOLD, Tone/Pulse, Flash, MUTE, ad-
justable Ringer and Loudhearing levels..) are pro-
grammable by MCU.
Also high-range telephone set can be built around
TEA7091 by adding Handsfree controller
(TEA7540), Electronic Hook Switch and upgraded
PINS CONNECTION (Top views)
MCU (ST family) with LCD driver.
The concept using TAFE + Microcontroller is
called BICHIP approach.
The benefits of this concept are:
– Saving of external components.
– Easy upgrade of the features (extra memories,
LCD driver, Answering machine or Cordless in-
terface..) through microcontroller.
– Replacement of configuration switches (PABX
/Public, Tone/Pulse...) by EEPROM settings.
This also induces reliability and cost improve-
ment.
