If the message lasts longer than 20 seconds, recording will terminate automatically after the last available memory cell is written. Playback Mode Edge-Activated Playback always starts from the beginning of the message. It is designed to be used as a building block in other projects where a.

The IC consists of a stereo modulator for generating stereo apr301 signals and a FM transmitter More information. Pins 23 and 27 have internal pull-up resistors. Download datasheet Kb Share this page. Current consumption is vatasheet less than 1uA. It encodes data and address pins into a serial coded waveform suitable. When pins are connected as shown in this example,the operating modes are as follows: Help me write a code for APR voice recorder.

VO1 General Description The TS is a low power audio amplifier, it integrated circuit intended primarily for telephone. B No part of this document may be reproduced, stored in a retrieval system, or transmitted in any form or by any means, mechanical.



Placement Features More datsheet. The gain is internally set to 20 to keep external part count. When pins are connected as shown in this example,the operating modes are as follows: The gain is internally set to 20 to keep external part count More information. Video signal switcher for AV amplifiers ideo signal switcher for A amplifiers BA The BA is a video signal switch that contains two five-channel analog multiplexers and wide-band 6dB amplifiers.

Record Mode Level-Activated A single voice message of up to 20 seconds can be recorded. What part of circuit are you having problem?

Single message of 20 to 30 seconds, with external resistor selection. The display level range is 9mVrms to mVrms Typ. It is capable of 18 functions and a total of 75 commands. Figure 4 shows the same application using external microphone biasing instead of the microphone amplifier on the APR device, thus bypassing the preamplifier portion of the chip function.

Hi people, I am planning to make an home appliance control using mobile phone project just for a hobby. C monolithic integrated circuit. I am doing a mini project on voice guider for old people using apr ,,i am tryng to record voice using microphone in apr ,but the busy pin dagasheet always glows and there is no beep sound from the speaker when we try to start recording,,what should i do??


Flash non-volatile memory cells,each of which can typically store more than voltage. The APR device offers true single-chip solid-state storage capability and requires no software or microcont-roller support. The A version is recommended for 5V designs and the B version More information.

Figure 2 shows the functional block diagram for the APR device. The A version is recommended for 5V designs and the B version.
