ISD4002 SERIES

6. PIN DESCRIPTION

PIN NAME

PIN NO.

FUNCTION

SOIC /

PDIP

TSOP

Slave Select: This input, when LOW, will select the

ISD4002 device.

MOSI

Master Out Slave IN: This is the serial input to the

ISD4002 device when it is configured as slave. The master

microcontroller places data on the MOSI line one half-cycle

before the rising edge of SCLK for clocking into the device.

MISO

Master In Slave Out: This is the serial output (open drain)

of the ISD4002 device. This output goes into a high-

impedance state if the device is not selected.

Ground: The ISD4002 series utilizes separate analog and

digital ground busses. The analog ground (V_SSA) pins

should be tied together as close as possible and connected

through a low-impedance path to power supply ground.

The digital ground (V_SSD) pin should be connected through

a separate low-impedance path to power supply ground.

These ground paths should be large enough to ensure that

the impedance between the V_SSApins and the V_SSDpin is

less than 3 Ω. The backside of the die is connected to V_SS

through the substrate. For chip-on-board design, the die

attach area must be connected to V_SSor left floating.

Not connected

AUD OUT ^[1]

Audio Output: This pin provides an audio output of the

stored data and is recommended be AC coupled. It is

capable of driving a 5 KΩ impedance R_EXT

[1]

The AUD OUT pin is always at 1.2 volts when the device is powered up. When in playback, the output buffer

connected to this pin can drive a load as small as 5 KΩ. When in record, a resistor connects AUD OUT to the

internal 1.2-volt analog ground supply. This resistor is approximately 850 KΩ, but will vary somewhat according to

the sample rate of the device. This relatively high impedance allows this pin to be connected to an audio bus

without loading it down.
