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 (
• Supply voltage: 2.4V to 5.5V.
• External resistor, Rosc, selects sampling frequency and duration.
• Mic+/Mic- : differential microphone inputs.
• AGC : automatic gain control for microphone preamp circuit.
•
• When both
• SP+/SP- : Class-D PWM differential speaker drivers.
•
• 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
NORM ) and direct trigger ( MODE ). The analog inputs and the outputs are:
Sampling Frequency 12 kHz 8 kHz 6.4 kHz 5.3 kHz 4 kHz
Rosc 53.3 KΩ 80 KΩ 100 KΩ 120 KΩ 160 KΩ
FT : feed-through the AnaIn signal to the speaker outputs while AnaIn is converted from MIC+.

2.1. Address trigger operational mode
• While in NORM mode, flexible message duration is defined by start address and end
address.
Utilize four start addresses ( S0 , S1 , S2 & S3 ) and four end addresses ( E0 , E1 , E2 & E3 ) to
•
specific the message duration.
•
REC : Level-hold or Edge-trigger (toggle on-off) recording from start to end addresses.
PLAYE : Edge-trigger playback from start to end addresses and stops at EOM marker, if EOM
•
is prior to end address. Toggle on-off.
• PLAYL : Level-hold playback from start to end addresses. Also, if constantly Low, device will
loop playback from start to end addresses.
2.2. Direct trigger operational mode
• While
adapt various (1 to 8) fixed equal message configurations for random access and pre-defines
the fixed message duration accordingly.
• The control pins are:
• The record or playback operation is pre-defined by the
• Each message can be randomly accessed via its message control pin (
desired operation is facilitated accordingly.
