1. GENERAL DESCRIPTION
Winbond’s ISD14B20 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 ISD14B20 is a multiple messages record/playback device with two operational modes: address
trigger (
) and direct trigger (
NORM
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
12 kHz
Rosc
53.3 K
Mic+/Mic- : differential microphone inputs.
8 kHz
80 K
6.4 kHz
100 K
5.3 kHz
120 K
4 kHz
160 K
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.

Packaging: die only
LED
: during recording, LED is on.
Automatically power down after each operation cycle.
Playback takes precedence over the recording operation.
