NSAM266SC CompactSPEECH^TMDigital Speech

Processor with Caller-ID Support

General Description

The NSAM266SC is a member of National Semiconductor’s

CompactSPEECH Digital Speech Processor family. This

processor provides Digital Answering Machine (DAM) func-

tionality to embedded systems.

The CompactSPEECH firmware implements voice compres-

sion and decompression, tone detection and generation,

message storage management, speech synthesis for time-

and-day stamp, and supports user-defined voice prompts in

various languages.

The CompactSPEECH interfaces with National Semicon-

ductor’s NM29A040 and NM29A080 Serial Flash memory

devices to provide a cost-effective solution for DAM and

Cordless DAM (CDAM) applications.

The CompactSPEECH Caller ID feature complies with the

Bellcore standard used in the USA. It implements the re-

ceiver side for data transmitted from the central office to the

subscriber.

The CompactSPEECH processor integrates the functions of

a traditional Digital Signal Processing (DSP) chip and the

CR16A, a 16-bit general-purpose RISC core implementation

of the CompactRISC^TMarchitecture. It contains system sup-

port functions such as Interrupt Control Unit. Codec inter-

face, MICROWIRE^TMinterfaces to a microcontroller and

Serial Flash, WATCHDOG^TMtimer, and a Clock Generator.

The CompactSPEECH implements echo-cancellation tech-

niques to support high-quality DTMF tone detection during

message playback.

The CompactSPEECH can synthesize messages in various

languages via the International Vocabulary Support (IVS)

mechanism. The NSAM266SC can store vocabularies on

either Serial Flash, or Expansion ROM memories. DAM

manufacturers can thus create machines that ‘‘speak’’ in

different languages, simply by using other vocabularies. For

more details about IVS, refer to the IVS User’s Manual.

The CompactSPEECH processor operates as a slave pe-

ripheral that is controlled by an external microcontroller via

a serial MICROWIRE interface. In a typical DAM environ-

ment, the microcontroller controls the analog circuits, but-

tons and display, and activates the CompactSPEECH by

sending it commands. The CompactSPEECH processor ex-

ecutes the commands and returns status information to the

microcontroller.
