Description

The A TSAM2193 provides a single-chip, low-cost MIDI sound system. Equipped with a serial and a parallel MIDI input, it provides state-of-the-art sound synthesis using a full GM sound set together with a range of compatible effects. Its low power consump- tion makes it ideal for all battery-powered applications such as portable Karaoke or any other device using MIDI synthesis. The ATSAM2193-G has the same functionality as the ATSAM2193 but is presented in a TFBGA44 package. Figure 1. Typical Hardware Configuration

2695A–DRMSD–06/03 Recommended Board Layout Like all HCMOS high integration ICs, the following simple rules of board layout are man- datory for reliable operation:  GND, VC3, VC2 Distribution and Decouplings All GND, VC3, VC2 pins should be connected. A GND plane is strongly recommended below the ATSAM2193 and ATSAM2193-G. The board GND + VC2 distribution should be in grid form. Recommended VC2 decoupling is 0.1 µF at each corner of the IC with an additional 10 µF between pins 42 and 44 for the ATSAM2193 and between pins G6 and F7 for the ATSAM2193-G. VC3 requires a single 0.1 uF decoupling.  Crystal, LFT The paths between the crystal, the crystal compensation capacitors, the LFT filter R-C- R and the device should be short and shielded. The ground return from the compensa- tion capacitors and LFT filter should be the GND plane from the device.  Analog Section A specific AGND ground plane should be provided, which is connected to the GND ground by a single trace. No digital signals should cross the AGND plane. Refer to the Codec vendor recommended layout for correct implementation of the ana- log section.
