MSM6679AL-110 Voice Recognition Processor
Typical Configurations
1.
2.
3.
The MSM6679AL-110 supports 32 Kbytes of RAM, and up to 64 Kbytes of ROM (EPROM or
Flash) per bank in separate memory spaces.
For accessing the ROM and RAM address spaces, the MSM6679AL-110 provides the separate
Write RAM (WRRAM) and Read RAM (RDRAM) signals. The RDRAM signals connect directly
to Output Enable (OE) control signal inputs on the RAM and ROM, respectively. The WRRAM
signal connects directly to the Write Enable (WE) control signal input on the RAM.

Application
Phrase chaining features usually permit much longer overall playback durations; not
including external speech synthesizer.
SD recognition vocabularies are volatile in these configurations.
Per download. Vocabulary swapping by host permits unlimited vocabulary size.
