I2361YYI
The I2361YYI is a playback only digital ChipCorder® based on flash storage. The device features both internal and external flash support, digital de-compression, comprehensive memory management, integrated audio signal path with up to 3 channel concurrent playback. The I2361YYI integrates a Class-D speaker driver capable of delivering 1W power output.
The I2361YYI requires no external clock sources or components to operate. It can operate under SPI mode, or operate in stand-alone by detecting on level transition on its GPIO pins.
The I2361YYI has 2 Mbit non-volatile flash built-in, and supports external NOR serial flash up to 2 Gbit.
