6 / 26 page I1800 SERIES 6. PIN DESCRIPTION PIN NAME PIN NO. I/O FUNCTION VSSD, VSSA 1, 16 Ground Supplies: Similar to VCCA and VCCD, the analog and digital circuits internal to the I1800 device use separate ground buses to minimize noise. These pins should be tied together as close as possible to the device. REC 1 2 I Record: The REC input is an active-HIGH record signal. The device records whenever REC is HIGH. This pin must remain HIGH for the duration of the recording. REC takes precedence over either playback (PLAYL or PLAYE) signal. If REC is pulled HIGH during a playback cycle, the playback immediately ceases and recording begins. A record cycle is completed when REC is pulled LOW. An End-of-Message (EOM) marker is internally recorded, enabling a subsequent playback cycle to terminate appropriately. The device automatically powers down to standby mode when REC goes LOW. This pin has an internal pull-down device. Holding this pin HIGH will increase standby current consumption. PLAYE 3 I Playback, Edge-activated: When a HIGH-going transition is detected on this input pin, a playback cycle begins. Playback continues until an End-of- Message (EOM) marker is encountered or the end of the memory space is reached. Upon completion of the playback cycle, the device automatically powers down into standby mode. Taking PLAYE LOW during a playback cycle will not terminate the current cycle. This pin has an internal pull-down device. Holding this pin HIGH will increase standby current consumption. PLAYL 4 I Playback, Level-activated: When this input pin level transits from LOW to HIGH, a playback cycle is initiated. Playback continues until PLAYL is pulled LOW or an End-of-Message (EOM) marker is detected, or the end of the memory space is reached. The device automatically powers down to standby mode upon completion of the playback cycle. This pin has an internal pull-down device. Holding this pin HIGH will increase standby current consumption. NC 5, 6, 7, 8, 9, 11, 14, 20, 21, 22, 23, 24 Not Connected. - 6 - |
