DESCRIPTION
ST75C530 and ST75C540 are two super-inte-
grated devices including DSP, Modem and Audio
Analog Front Ends and memories for Telephony,
Modem and FAXapplications.
These devices can be used for classical applica-
tionsover POTS lines or over Internet.
The super integration technology allows a signifi-
cant cost reduction on bill of materials for equip-
ment like High-End phones, INTERNET phones,
phone-Fax,INTERNET FAX, ...
The devices are used with a host processor
througha Dual Port RAM allowing the use of any
kind of microcontroller (RISC, CISC,General Pur-
pose 8-bit
μ
C, ...).
This is advanceinformation on a new product now in developmentor undergoingevaluation . Detailsare subject to changewithout notice.
The embeddedsoftware includes :
- handsetwith listeninggroup capability,
- full duplex handsfree,
- voicecoder/decoderat 4.8Kbpsforstaticanswer-
ing machine applications and ADPCM 16Kbps,
24Kbps and 32Kbps for high quality message
recording,
- Tone and DTMF generators,
- Tone and DTMF detectors,
- FAXup to 14.4Kbps,
- Data-Modemup to 14.4Kbps(ST75C540 only).
The DSP sofware is extensively user configurable
allowing specific functions to be supported like
Caller Identifier (CLID) and Second Call Waiting
Identifier(SCWID).
The DSP software includes a transparent mode
allowing the host controller to access directly the
modem Analog Front End and the Audio AFE
through the dual Port RAM. This is veryuseful for
hostprocessingmodem solutions (or soft modem)
wherethe modulationandthedemodulation(V.34,
V.90) are done by the applicationmain processor.
In transparent mode, the embedded DSP can be
used simultaneouslywith the samesamples.
The transparentmode foraudioAFEis providedto
play audio files or to recordvoice and/or audio.
