Address/Mode Inputs: The Address/Mode Inputs have two functions

depending on the level of the two Most Significant Bits (MSB) of the

address pins A7 and A8.

/ M0, M1,

/ 1, 2,

/ 8, 9,

If either or both of the two MSBs are LOW, the inputs are all interpreted

as address bits and are used as the start address for the current record

or playback cycle. The address pins are inputs only and do not output

any internal address information during the operation. Address inputs

M2, M3,

3, 4,

10, 11,

M4, M5, M6

5, 6, 7 12, 13, 14

are latched by the falling edge of CE.

If both MSBs are HIGH, the Address/Mode inputs are interpreted as

Mode bits according to the Operational Mode table on page 12. There

are six operational modes (M0…M6) available as indicated in the table.

It is possible to use multiple operational modes simultaneously.

Operational Modes are sampled on each falling edge of CE, and thus

Operational Modes and direct addressing are mutually exclusive.

AUX IN

No Connect.

Auxiliary Input: The Auxiliary Input is multiplexed through to the output

amplifier and speaker output pins when CE is HIGH, P/R is HIGH,

and playback is currently not active or if the device is in playback

overflow. When cascading multiple ISD2500 devices, the AUX IN pin is

used to connect a playback signal from a following device to the

previous output speaker drivers. For noise considerations, it is

suggested that the auxiliary input not be driven when the storage array

is active.

Ground: The ISD2500 series of devices utilizes separate analog and

digital ground busses. These pins should be connected separately

through a low-impedance path to power supply ground.

Speaker Outputs: All devices in the ISD2500 series include an on-chip

differential speaker driver, capable of driving 50 mW into 16 Ω from

AUX IN (12.2mW from memory).

^[1]The speaker outputs are held at V_SSAlevels during record and power

down. It is therefore not possible to parallel speaker outputs of multiple

ISD2500 devices or the outputs of other speaker drivers.

[2]

A single-end output may be used (including a coupling capacitor

between the SP pin and the speaker). These outputs may be used

individually with the output signal taken from either pin. However, the

use of single-end output results in a 1 to 4 reduction in its output power.

[1]

[2]

Connection of speaker outputs in parallel may cause damage to the device.

Never ground or drive an unused speaker output.
