APR6016 Datasheet PDF
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. Each memory cell can typically store voltage.
A0] bits according to the following binary values APR Follow Summary Starts a record operation from the sector address specified. The APR is ideal for use in cellular and cordless phones, telephone answering devices, personal digital assistants, personal voice ecorders,and voice pagers.
Starts a record operation from the current sector address. APR devices can be cascaded for longer duration recording or greater digital storage. The APR is ideal for use in cellular.

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. Both blocks are optional. Absolute Maximum Ratings Stresses greater than those listed in Table 4 may cause permanent damage to the device.
Device control is accomplished through an industry standard SPI interface that allows a microcontroller to manage message recording and playback. The following two columns represent the actual binary information contained in the 20 bit data stream. Erase should not be done before recording voice signals into a sector.
This allows the APR voice to reproduce audio. Copy your embed code and put on your site: APR datasheet and specification datasheet. Four additional buffer bits must be clocked into the device following the stored data An incomplete read is defined as a read with less than clock cycles. The last seven bits are random data and should be ignored Erase must be done before storing digital data in a sector This flag is cleared http: The Overflow flag is set overflow has not occurred.
Device status and silicon ID are described in the next two sections. The following five bits represent the product family. You must not erase a sector before recording voice signals into it Up to 16 minutes of audio recording and playback can be accommodated. These signals can simplify message management significantly depending on the message management scheme used. It also contains the status register used for examining the current status of the APR The default power up condition for the APR is to use the internal oscillator at sampling frequency of 6.
This circuit decodes all the SPI signals and generates all the internal control signals. The next four bits represent the device code. APR datasheet and specification datasheet Download datasheet. Elcodis is a trademark of Elcodis Company Ltd. Up to 16 minutes of. A max- imum of 30K bits of digital data can be stored.
This flexible arrangement allows for the widest variety of messaging options. All other trademarks are the property of their respective owners. All bits must be stored. Device status, Silicon ID and user stored data. Several vendors supply integrated speaker amplifiers that can be used for this purpose. When the first sector The name of the OpCode appears in the left hand column.
The APR device code is binary as shown in Figure An interrupt is generated http: For more information see the section entitled Recording Audio Data. Some commands have limits on which command can follow them. The APR is ideal for use datasheeet cellular and cordless phones, telephone answering devices, personal digital assistants, personal voice recorders, and voice pag- ers. Erases all data contained in specified sector.
