5. PIN DESCRIPTION

PIN NAME

PIN #

FUNCTION

SOIC /

PDIP

Slave Select: This input, when LOW, will select the ISD4004 device.

MOSI

Master Out Slave IN: This is the serial input to the ISD4004 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 of the ISD4004 device. This

output goes into a high-impedance state if the device is not selected.

V_SSA/ V_SSD

11, 12, Ground: The ISD4004 series utilizes separate analog and digital ground

23 / 4

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_SSthrough the substrate. For chip-on-board design, the die attach area

must be connected to V_SSor left floating.

Not connected

AUD OUT ^[1]

AM CAP

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

AutoMute™ Feature: The AutoMute feature only applies for playback

operation and helps to minimize noise (with 6 dB of attenuation) when there

is no signal (i.e. during periods of silence). A 1 µF capacitor to ground is

recommended to connect to the AM CAP pin.

This capacitor becomes a part of an internal peak detector which senses the

signal amplitude. This peak level is compared to an internally set threshold

to determine the AutoMute trip point. For large signals, the AutoMute

attenuation is set to 0 dB automatically but 6 dB of attenuation occurs for

silence. The 1 µF capacitor also affects the rate at which the AutoMute

feature changes with the signal amplitude (or the attack time).

The AutoMute feature can be disabled by connecting the AM CAP pin

directly to V_CCA..

[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 built-in 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.
