Note:

1.

Changing the sample rate (by changing the crystal frequency) will change the maximum delay

available through the DRAM proportionally. Low sample rates require more refresh instructions.

2.

XtalIn, XtalOut are special pins designed to be connected to a crystal. XtalOut is a relatively weak pin

(about 0.2 mA) and should not be used to drive external circuits. Instead of using a crystal, XtalIn

3.

All other voltages are relative to Gnd.

4.

Bypass (pin 14) must never exceed 3.6V
