FLASH STORAGE
One of the benefits of Nuvoton’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 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: 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 I2C port. Once the desired
message configuration is created, duplicates can easily be generated via a Nuvoton or third-party
programmer. For more information on available application tools and programmers, please see the
Nuvoton web site at http://www.Nuvoton-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.
