5. PIN DESCRIPTION

PIN NAME

PIN NO.

1, 16

I/O

FUNCTION

V_SSD, V_SSA

Ground Supplies: Similar to V_CCAand V_CCD, 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

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

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

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

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.
