Complete one chip TAD solution
with AFlash and DRAM memory interface
Overview:
The W62410 chip is a digital speech signal processor. The W62410 implements the STREAMTALK
speech compression, voice prompt processing, telephone line signal processing, AFlash and DRAM
memory management and 13 I/O lines all in one chip for a fully digital answering machine. The W62410
acts as a slave processor to its host. The W62410 can be driven through a serial bus or an 8 bit parallel bus
allowing the possibility for both 4 bit and 8 bit micro controllers to be used. Since the W62410 is a slave
to the host, the host is responsible for activating and deactivating all the functions the W62410 provides.
Since there are no moving parts, this all-digital solution results in a very high reliability.
Features:
High quality STREAMTALK
4.8 Kbps
digital speech compression algorithm allowing
16-19 minutes of recording time per each 4
Mbit of memory.
Virtually unlimited number of incoming
messages (ICM) and memo recordings
completely managed by the W62410 chip.
Support for up to eight mailboxes completely
managed by the W62410 chip.
Support for up to 32 outgoing messages
(OGM’s).
STREAMTALK
, natural sounding voice
prompts. Also allows variable pause lengths
between each word for Day/Time stamps and
voice instructions.
Variable speed playback without change of the
speakers pitch (50%-200%).
A very fast forward playback at 400% without
change of the speakers pitch.
DTMF generation and detection with near-end
echo cancellation for enhanced performance.
Extended DTMF support (generates and
detects A, B, C, and D tones).
