1. OVERVIEW  
1.1 SPEECH/SOUND QUALITY  
The ISD5116 ChipCorder product can be configured via software to operate at 4.0, 5.3, 6.4 and 8.0 kHz  
sampling frequencies, allowing the user a choice of speech quality options. Increasing the duration  
decreases the sampling frequency and bandwidth, which affects sound quality. The table in the following  
section compares filter pass band and product durations.  
1.2 DURATION  
To meet end-system requirements, the ISD5116 device is a single-chip solution, which provides from 8 to  
16 minutes of voice record and playback, depending on the sample rates defined by customer software.

1.3 FLASH STORAGE  
One of the benefits of ISD’s ChipCorder technology is the use of on-chip nonvolatile memory, which  
provides zero-power message storage. The message is retained for up to 100 years (typically) without  
power. In addition, the device can be re-recorded over 10,000 times (typically) for the digital messages  
and over 100,000 times (typically) for the analog messages.  
A new feature has been added that allows memory space in the ISD5116 to be allocated to either digital  
or analog storage when recorded. The fact that a section has been assigned digital or analog data is  
stored in the Message Address Table by the system microcontroller when the recording is made.  
1.4 MICROCONTROLLER INTERFACE  
The ISD5116 is controlled through an I2C 2-wire interface. This synchronous serial port allows  
commands, configurations, address data, and digital data to be loaded to the device, while allowing  
status, digital data and current address information to be read back from the device. In addition to the  
serial interface, two other pins can be connected to the microcontroller for enhanced interface. These are  
the RAC timing pin and the INT pin for interrupts to the controller. Communications with all the internal  
registers are through the serial bus, as well as digital memory Read and Write operations.  
1.5 PROGRAMMING  
The ISD5116 series is also ideal for playback-only applications, where single or multiple messages may  
be played back when desired. Playback is controlled through the I2C interface. Once the desired message  
configuration is created, duplicates can easily be generated via a third-party programmer. For more
