NOTES:

All parameters apply to both commercial and industrial temperature operation unless otherwise noted.

All voltages are referenced to ground.

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

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

Idle mode IIDLE is measured with all output pins disconnected; XTAL1 driven with tCLKR, tCLKF =

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

Stop mode ISTOP is measured with all output pins disconnected; PORT0 = VCC; XTAL2 not

connected; RST = MSEL = XTAL1 = VSS.

Pin capacitance is measured with a test frequency - 1 MHz, tA = 25°C.

ICCO1 is the maximum average operating current that can be drawn from VCCO in normal operation.

ILI is the current drawn from VLI input when VCC = 0V and VCCO is disconnected. Battery-backed

mode: 2.5V

£ VBAT £ 4.0; VCC £ VBAT; VSDI should be £ VILS for IBAT max.

VCCO2 is measured with VCC < VLI, and a maximum load of 10 µA on VCCO.

Crystal start-up 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 a worst case specification on

this time.

10.

SDI is deglitched to prevent accidental destruction. The pulse must be longer than tSPR to pass the

deglitcher, but SDI is not guaranteed unless it is longer than tSPA.

11.

VIHS minimum is 2.0V or VCCO, whichever is lower.

12.

This parameter applies to industrial temperature operation.

13.

pin operation is specified with VBAT

³ 3.0V.
