Nuvoton Claims First One Battery Speech IC Solution

The operation voltage of N584Lxxx ranges from 1.0 to 1.8V that is suitable for one battery application. Meanwhile, a 4bit uC is built-in to implement multi-tasking applications and provides 8 I/O pins via Ultra I/O™ function to drive LEDs with high resolution fading effect as well. 2 I/O of them have higher sink capability to drive external LEDs directly without extra amplify component to save BOM cost. N584Lxxx also provides carrier of 38KHz for IR application.

For voice output, N584Lxxx offers a PWM with 9-bit resolution to drive speaker directly. In addition, via 5-bit MDPCM algorithm makes tone have more exquisite quality. N584Lxxx also provides dual tone melody and mixer device to playback voice and melody simultaneously.

N584Lxxx series has three items with different durations (20sec, 30 sec, 40 sec) for various demands, including N584L020, N584L030 and N584L040. Besides, Nuvoton provides complete development tools with source level debugging as well as high level language to help customers develop new projects in a more efficient way.
