Description
The TJ3964GRS-2.5 is an electronic component model in the IC Chips product category. It is a third-generation single-chip highly integrated digital music system solution for audio players and other devices. The chip includes an audio decoder with embedded RAM and ROM, ADPCM record capabilities, and a USB interface for music download and voice recording upload. It also supports various interfaces such as SPDIF, flash memory, LED/LCD, buttons, switches, headphones, microphone, and FM radio input and control. The chip supports WMA and other digital audio standards and can act as a USB mass storage slave device to a personal computer. It features low power consumption, a flexible on-chip DC-DC converter, and support for different battery configurations. The built-in Sigma-Delta D/A includes a headphone driver and the A/D includes inputs for both microphone and analog audio. It provides a highly optimized all-in-one solution for digital audio players.
