NOTES:

1. All voltages are referenced to ground.

2. Maximum operating ICC is measured with all output pins disconnected; XTAL1 driven with tCLKR,

tCLKF = 10ns, VIL = 0.5V; XTAL2 disconnected; EA = RST = PORT0 = VCC.

3. Idle mode ICC is measured with all output pins disconnected; XTAL1 driven at 12MHz with tCLKR,

tCLKF = 10ns, VIL = 0.5V; XTAL2 disconnected; EA = PORT0 = VCC, RST = VSS.

4. Stop mode ICC is measured with all output pins disconnected; EA = PORT0 = VCC; XTAL2 not

connected; RST = VSS.

5. Crystal startup time is the time required to get the mass of the crystal into vibrational motion from the

time that power is first applied to the circuit until the first clock pulse is produced by the on-chip

oscillator. The user should check with the crystal vendor for the worst-case spec on this time.

6. Assumes VLI = 3.3V maximum.

7. ILI is the current drawn from VLI when VCC = 0V and VCCO is disconnected.

8. I CCO = 10

mA.
