EM6812

Circuit Connectivity

The EM6812 has the same pin-out in both the SO24 and TSSOP24 pin package.

Minimum connectivity includes the power supply on V_SSand V_DD, a capacitor on Vreg, and de-coupling capacitance on V_DD

Circuit reference terminal (substrate) is on V_SS

The 32kHz Crystal is only needed for systems requiring low frequency Crystal operation.

The integrated supply voltage regulator filters supply noise and allows lowest power peripheral operations. For proper

operation, a capacitor (470nF minimum) must be connected to the regulator’s VREG terminal. This terminal must not be

used for any other outside connection.

Note:

•

ALL circuit IO's (except OscIn) are on V_DDlevel. OscIn terminal is only used in conjunction with an quartz Crystal. The

terminal input voltages must never exceed the Vreg voltage.

•

The quartz crystal should be shielded with V_SSto keep noise away.

When using the Crystal oscillator PA[7] and PA[6] should preferably used as static inputs only to avoid noise coupling

on the OscIn and OscOut high impedance inputs.
