The Overflow flag is set overflow has not occurred. APR devices can be cascaded for longer duration recording or greater digital storage. These specifications represent a stress rating only. This circuit decodes all the SPI signals and generates all the internal control signals.
Download datasheet Kb Share this page. All bits must be stored. You must not erase a sector before recording voice signals into it This flexible arrangement allows for the widest variety of. Several vendors supply integrated speaker amplifiers that can be used for this purpose. An interrupt is generated http: The default power up condition for the APR is to use the internal oscillator at sampling frequency of 6.
Four additional buffer bits must be clocked into the device following the stored data The name of the OpCode appears in the left hand column. An incomplete read is defined as a read with less than clock cycles. Each memory cell can typically store voltage.
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.
Starts a record operation from the current sector address. These bits will not be stored in the array and must be considered don’t care bits.

Erase should not be done before recording voice signals into a sector. Up to 16 minutes of. The last seven bits are random data and should be ignored The following five bits represent the product family.
When the first sector It also contains the status register used for examining the current status of the APR Device control is accomplished. The next four bits represent the device code. The APR is ideal for use in cellular. There are four random don’t care bits following the bits of user data. Device control is accomplished through an industry standard SPI interface that allows aprr6016 microcontroller to manage message recording and playback.

The APR is ideal for use in cellular and cordless phones, telephone answering devices, personal digital assistants, personal voice ecorders,and voice pagers. A microphone amplifier and AGC are recommended. This flexible arrangement allows for the widest variety of messaging options. Elcodis is a trademark of Elcodis Company Ltd. Both blocks are optional. This flag is cleared http: Absolute Maximum Ratings Stresses greater than those listed in Table 4 may cause permanent damage to the device.
Up to 16 minutes of audio recording and playback can be accommodated. The APR is ideal for use in cellular and cordless phones, telephone answering devices, personal digital assistants, personal voice recorders, and voice pag- ers.
All other trademarks are the property of their respective owners. A max- imum of 30K bits of digital data can be stored. This flexible arrangement allows for the widest variety of messaging options. Device status and silicon ID are described in the next two sections.
Device status, Silicon ID and user stored data. Erases all data contained in specified sector. The following two columns represent the actual binary information contained in the 20 bit data stream. APR datasheet and specification datasheet Download datasheet.

Erase must be done before storing digital data in a dataasheet Some commands have limits on which command can follow them. 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. Copy your embed code and put on your site: Each memory cell can typically store voltage levels. The APR device code is binary as shown in Figure APR datasheet and specification datasheet.
This allows the APR voice to reproduce audio. SPI interface that allows a microcontroller to manage message recording and playback. SPI interface section paragraph.
