ISD1916

1. GENERAL DESCRIPTION

Winbond’s ISD1916 ChipCorder^®is a new single-chip multiple-message record/playback series with

dual operating modes (address trigger and direct trigger) with wide operating voltage ranging from

2.4V to 5.5V. The sampling frequency can be selected from 4 to 12 kHz via an external resistor, which

also determines the duration from 10.6 to 32 seconds. The device is designed for mostly standalone

applications, and of course, it can be manipulated by a microcontroller, if necessary.

The two operating modes are address trigger and direct trigger. While in address trigger mode, both

record and playback operations are manipulated according to the start address and end address

specified through the start address and end address pins. However, in direct trigger mode, the device

can configure the memory up to as many as eight equal messages, pending upon the fixed message

configuration settings. With the record or playback feature being pre-selected, each message can be

randomly accessed via its message control pin.

The device has a selectable differential microphone input with AGC feature or single-ended analog

input, AnaIn, under feed-through mode. Its differential Class D PWM speaker driver can directly drive

a typical speaker or buzzer.

2. FEATURES

The ISD1916 is a multiple messages record/playback device with two operational modes: address

trigger (NORM ) and direct trigger (MODE ). The analog inputs and the outputs are:

•

Supply voltage: 2.4V to 5.5V.

External resistor, Rosc, selects sampling frequency and duration.

Sampling Frequency

Rosc

12 kHz

53.3 KΩ

8 kHz

80 KΩ

6.4 kHz

100 KΩ

5.3 kHz

120 KΩ

4 kHz

160 KΩ

•

Mic+/Mic- : differential microphone inputs.

AGC : automatic gain control for microphone preamp circuit.

FT : feed-through the AnaIn signal to the speaker outputs while AnaIn is converted from MIC+.

When both FT and recording are active, device will record AnaIn signal into memory with AnaIn

signal output to speaker simultaneously.

•

SP+/SP- : Class-D PWM differential speaker drivers.

LED : during recording, LED is on.

Automatically power down after each operation cycle.

Playback takes precedence over the recording operation.

y Temperature option: -40°C to +85°C (Industrial)

y Packaging: available in SOIC only
