ISD1800 SERIES

PIN NAME

PIN NO.

I/O

FUNCTION

V_CCA, V_CCD

18, 27

Voltage Supplies: Analog and digital circuits

internal to the I1800 device use separate power

buses to minimize noise on the chip. These power

buses are brought out to separate pins on the

package and should be tied together as close to

the power supply as possible. It is important that

the power supply be decoupled as close as

possible to the package.

ROSC

The Resistor Controlled Oscillator input: This

enables the user to vary the I1800 device record

and playback duration. The resistor connected

between the ROSC pin and V_SS(R2) determines

the sample frequency and the filter upper pass

band for the I1800 device. Please refer to the

table in Duration Section for duration selection.

Feed Through: This mode allows use of the

speaker drivers for external signals. The signal

between the MIC and MIC_REF pins will pass

through the AGC, the filter and the speaker

drivers to the speaker outputs SP+ and SP-. The

input FT controls the feed through mode. To

operate this mode, the control pins REC, PLAYE

and PLAYL are held LOW at V_SS. The pin FT is

held HIGH to V_CC. For normal operation of record,

play and power down, the FT pin is held at V_SS.

The FT pin has a weak pull-down to V_SS.

XCLK

The External Clock input: For the I1800 devices

has an internal pull-down resistor. This pin is used

for test purposes only. Do not bond this pad.

RECLED

Record LED output: The RECLED output is

LOW during a record cycle. It can be used to drive

an LED to provide feedback that a record cycle is

in progress. In addition, RECLED pulses LOW

momentarily when and End-of-Message (EOM) or

end-of-memory marker is encountered in a

playback cycle.

Note: ¹The REC signal is internally debounced on the rising edge to prevent a false re-triggering from a push-

button switch.
