The APR is ideal for use in cellular and cordless phones, telephone answering devices, personal digital assistants, personal voice ecorders,and voice pagers. Copy your embed code and put on your site: Absolute Maximum Ratings Stresses greater than those listed in Table 4 may cause permanent damage to the device.
APR Aplus Integrated circuits Inc., APR Datasheet
For more information see the section entitled Recording Audio Data. The default power up condition for the APR is to use the internal oscillator at sampling frequency of 6. This allows the APR voice to reproduce audio signals in their natural form, eliminating the need for enco- ding and compression which can introduce distortion. APLUS Integrated achieves this high level of storage capabi- lity by using a proprietary analog multi-level storage te chnol – logy i mplemented in an advanced non-volatile Flash memory process.
The APR is ideal for use in cellular. Each memory cell can typically store voltage. A microphone amplifier and AGC are recommended.
Four additional buffer bits must be clocked into the device following the stored data All bits must be stored. It also contains the status register used for examining the current status of the APR This flag is cleared http: Device control is accomplished. The name of the OpCode appears in the left hand column.
Recording & Playback Voice IC
These signals can simplify message management significantly depending on the message management scheme used. The last seven bits are random data and should be ignored The following five bits represent the product family.
Both blocks are optional. Up to 16 minutes of audio recording and playback can be accommodated. A0] bits according to the following binary values APR Follow Summary Starts a record operation from the sector address specified. APR datasheet and specification datasheet. Starts a record operation from the current sector address. SPI interface that allows a microcontroller to manage message recording and playback.
An incomplete read is defined as a read with less than clock cycles.
The APR is ideal for use in cellular and cordless phones, telephone answering devices, personal digital assistants, personal voice recorders, and voice pag- ers. Erases all data contained in specified sector. The Overflow flag is set overflow has not occurred. Some commands have limits on which command can follow them. APR devices can be cascaded for longer duration recording or greater digital storage.
Device status, Silicon ID and user stored data. This circuit decodes all the SPI signals and generates all the internal control signals. Datasgeet are four random don’t care bits following the bits of user data. Download datasheet Kb Share this page. You must not erase a sector before recording voice signals into it This flexible arrangement allows for the widest variety of.
Aapr6016 max- imum of 30K bits of digital data can be stored. Erase must be done before storing digital data in a sector Several vendors supply integrated speaker amplifiers that can be used for this purpose. Dqtasheet is a trademark of Elcodis Company Ltd. SPI interface section paragraph. When the first sector The APR device code is binary as shown in Figure The following two columns represent the actual binary information contained in the 20 bit data stream.
This flexible arrangement allows for the widest variety of messaging options. An interrupt is generated http: Each memory cell can typically store voltage levels.
Erase should not be done before recording voice signals into a sector. This flexible dwtasheet allows for the widest variety of messaging options.
The next four bits represent the device code. This allows the APR voice to reproduce audio. These bits will not be stored in the array and must be considered don’t care bits. These specifications represent a stress rating only.
Device status and silicon ID are described in the next two sections. APR datasheet and specification datasheet Download datasheet. Device control is accomplished through an industry standard SPI interface that allows a microcontroller to manage message recording and playback.
