FLASH STORAGE

One of the benefits of Winbond’s ChipCorder technology is the use of on-chip nonvolatile memory,

which provides zero-power message storage. A 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 digital

messages and over 100,000 times (typically) for analog messages.

Memory space can be allocated to either digital or analog storage, when recording. The system micro

controller stores this information in the Message Address Table.

MICROCONTROLLER INTERFACE

The ISD5216 is controlled through an I

2C 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: the

RAC timing pin and the INT pin for interrupts to the controller. Communications with all of the internal

registers is through the serial bus, as well as digital memory Read and Write operations.

PROGRAMMING

The ISD5216 series is also ideal for playback-only applications, whereas single or multiple messages

may be played back when desired. Playback is controlled through the I

2C port. Once the desired

message configuration is created, duplicates can easily be generated via a Winbond or third-party

programmer. For more information on available application tools and programmers, please see the

Winbond web site at http://www.winbond-usa.com/.

AUDIO PATHS

The ISD5216 has extremely powerful audio routing functionality where all audio signals can be routed

and multiplexed to multiple destinations. A few examples are

Simultaneous recording of microphone input and CODEC DAC output for recording both parties

of a phone call.
