I5216 SERIES
Advanced Information
PRELIMINARY
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.
A new feature has been added that allows for the allocation of memory space in the I5216, to either
digital or analog storage, when recording. When making a recording, if a section is assigned for digital
or analog data storage, the system microcontroller stores this information in the Message Address
Table.
MICROCONTROLLER INTERFACE
The I5216 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 I5216 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 Winbond or third-party programmer.

APPLICATIONS
The I5216 is a single chip solution for voice and analog storage that also includes the capability to
store digital information in the memory array. The array may be divided between analog and digital
storage, as the user chooses, when configuring the device.
Looking at the block diagram on the following page, one can see that the I5216 may be very easily
designed into a cellular phone. Placing the device between the microphone and the existing baseband
chip takes care of the transmit path. The SDI/SDIO of the baseband chip is connected to the SDIO/SDI
of the I5216. Two pins are needed for the I²C digital control and digital information for storage.
