The following two columns represent the actual binary information contained in the 20 bit data stream. 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.
This flexible arrangement allows for the widest variety of messaging options. For more information see the section entitled Recording Audio Data. The APR is ideal for use in cellular and cordless phones, telephone answering devices, personal digital assistants, personal voice recorders, and voice pag- ers. APR datasheet and specification datasheet Download datasheet.
This allows the APR voice to reproduce audio. All bits must be stored. Up to 16 minutes of audio recording and playback can be accommodated.
All other trademarks are the property of their respective owners. A0] bits according to the following binary values APR Follow Summary Starts a record operation from the sector address specified. Both blocks are optional. Device control is accomplished through an industry standard SPI interface that allows a microcontroller to manage message recording and playback. The APR device code is binary as shown in Apr60116 Absolute Apt6016 Ratings Stresses greater than those listed in Table 4 may cause permanent damage to the device.

Erase dataseet be done before storing digital data in a sector The Overflow flag is set overflow has not occurred. Device status, Silicon ID and user stored data. Starts a record operation from the current sector address. APR datasheet and specification datasheet. The name of the OpCode appears in the left hand column. There are four random don’t care bits following the bits of user data.
This flexible arrangement allows for the widest variety of messaging apt6016. Each memory cell can typically store voltage levels. The last seven bits are random data and should be ignored The next four bits represent the device code. The APR is ideal for use in cellular and cordless phones, telephone answering devices, personal digital assistants, personal voice ecorders,and voice pagers.
APR devices can be cascaded for longer duration recording or greater digital storage. SPI interface section paragraph. A microphone amplifier and AGC are recommended.
The default power up condition for the APR is to use the internal oscillator at sampling frequency of 6. An interrupt is generated http: The following five bits represent the product family. A max- imum of 30K bits of digital data can be stored.
These bits will not be stored in the array and must be considered don’t care bits. SPI interface that allows a microcontroller to manage message recording and datashfet.
These specifications represent a stress rating only. This circuit decodes all the SPI signals and generates all the internal control signals.

Device control is accomplished. It also contains the status register used for examining the current status of the APR Device status and silicon ID are described in the next two sections. Some commands have limits on which command can follow them. You must not erase a sector before recording voice signals into it 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.
Up to 16 minutes of. This flag is cleared http: Erases all data contained in specified sector. When the first sector This flexible arrangement allows for the widest variety of.
