8 / 46 page ![]() MSM6679AL-110 Voice Recognition Processor ¡ Semiconductor 6 PIN DESCRIPTIONS Pin # Pin Name Signal Type Description 1 NC (do not connect) 2 Reserved. These pins are reserved for future used and must be left open. 3 RESOUT Output MSM665x Reaet. This pin provides a reset signal for an external speech synthesis engine. 4 STROBE Output MSM665x Strobe. This output provides the LOAD signal for an external speech synthesizer. 5 BUSY Input MSM665x Busy. When using an external MSM665x device, this pin monitors the MSM665x BUSY signal and connects directly to the MSM665x BUSY signal output. 6 SI Output MSM665x Serial Clock. This MSM6679AL-110 output connects to the MSM665x SI input. The SI pin is the MSM665x serial clock input pin. 7 SD Output MSM665x Serial Data. This MSM6679AL-110 output connects to the MSM665x SD input. The SD pin is the MSM665x serial data input pin. 8 NC (do not connect) Reserved. These pins are reserved for future use and must be left open. 9 10 VOICEOUT1 Output Voice Out. This pin is the PWM output for speech synthesis, voice sample playback, and voice prompts. An external integrator must be used to convert this to an analog signal. 11 NC (do not connect) Reserved. This pin is reserved for future use and must be left open. 12 NAR Input MSM665x Next Address Request. This pin signals to the MSM6679AL-110 that the external speech synthesis engine is ready for another command. 13 VDD Digital Power Power. 14 GND Digital Ground Ground. 15 NC Input Reserved. These pins are reserved for future use and must be tied to VDD. 16 17 18 NC (do not connect) Reserved. This pin is reserved for future use and must be left open. 19 NC Input Reserved. This pin is reserved for future use and must be tied to VDD. 20 PDC Input Power down release. Power down mode is released by both edge of PDC signal. |
