I3810YYI is a high-performance Digital ChipCorder^® device designed for external SPI flash-based audio playback with 3-channel mixing.

I3810YYI can be operated under SPI mode, I²C mode, or GPIO trigger mode. Audio playback sources include external SPI flash, I²S interface, or direct SPI data from the MCU. With 28-bit flash space addressing, it can support up to 2Gbit NOR flash. With multiple compression algorithms, it can support sample rates up to 48kHz.

A built-in high-efficiency, filter-free Class-D amplifier delivers up to 3.0W with 4Ω or 1.7W with 8Ω based on 5 V speaker power supply.
