Notes
1. A 3rd overtone crystal of 48 MHz must be used in combination with a filter connected to the oscillator output (XTAL2),
3. Use for calculation of the power-on reset set-up time the C
More information about the firmware, descriptors and configurations can be obtained from several application notes.

2. Strongly depends on the external decoupling capacitor connected to V
4. The audio information from the USB interface is fed directly to the ADAC.
APPLICATION INFORMATION
The UDA1331H can only be used in combination with an external (E)PROM. This (E)PROM can be connected to the
port pins (P0 and P2) of the UDA1331H and must contain the firmware for the microcontroller. The UDA1331H will be
delivered with standard USB compliant firmware.
