... The ISD1000A Series includes signal conditioning circuits and control functions which enable a com- plete, high-quality Recording and Playback sys- tem in a single device. The ISD1000A is available in two versions, which store voice in 16- or 20-sec- ond arrays. Additional devices may be cascaded Timing ...

... PIN DESCRIPTIONS Voltage Inputs (V To minimize noise, the analog and digital circuits in the ISD1000A Series devices use separate power busses. These voltage busses are brought out to separate pins and should be tied together as close to the supply as possible. In addition, these supplies should be decoupled as close to the package as possible ...

... The CE pin is taken LOW to enable all Playback and Record operations. The address inputs and Playback/Record input (P/R) are latched by the falling edge of CE. When CE is taken HIGH, the ISD1000A is unselected, the P/R is HIGH, and the auxiliary input is directed into the speaker ampli- fier. Playback/Record Input (P/R) The P/R input is latched by the falling edge of the CE pin ...

... EOM, allowing mes- Each CE LOW sages to be played back consecutively. M5 — CE Level Activated The default mode for ISD1000A devices is for edge-activated on Playback and level-acti- vated on Record. The M5 Operational Mode causes the CE pin to be interpreted as level-acti- vated as opposed to edge-activated during Play- back ...
