Data Sheet

V1.2, 2002-12

Preliminary

1) Digital supply voltages applied to the TC1765 must be static regulated voltages which allow a typical voltage

swing of

±10%.

2) Voltage overshoot to 6.5 V is permissible, provided that the pulse duration is less than 100

µs and the

cumulated summary of the pulses does not exceed 1 hour.

3) Voltage overshoot to 4 V is permissible, provided that the pulse duration is less than 100

µs and the cumulated

summary of the pulses does not exceed 1 hour.

4) In order to minimize the danger of latch-up conditions, these 2.5 V V

DD power supply pins should be kept at

the same voltage level during normal operating mode. This condition is typically achieved by generating the

2.5 V power supplies from a single voltage source. The condition is also valid in normal operating mode if a

separate stand-by power supply

VDDSBRAM is used.

5) The minimum voltage at pin V

DDSBRAM during TC1765 power down mode is 1.8 V in order to keep the contents

of SBRAM valid. The core power supply

VDD must be below the standby power supply VDD < VDDSBRAM +

0.3 V.

6) The value of V

AREF is permitted to be within the range of VSSA - 0.05 V < VAREF < VDDM + 0.05 V. The value

specified for the total unadjusted error (TUE) is not guaranteed while the

VAREF is out of the specified range.

7) The value of V

AGND is permitted to be within the range of VSSA - 0.05 V < VAGND < VDDM + 0.05 V. The value

specified for the total unadjusted error (TUE) is not guaranteed while the

VAGND is out of the specified range.

8) Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin

exceeds the specified range (i.e.

VOV > VDD + 0.5 V or VOV < VSS - 0.5 V). The absolute sum of input overload

currents on all port pins may not exceed 50 mA. The supply voltage must remain within the specified limits.

9) Not 100% tested, guaranteed by design and characterization.

10) Applicable for analog inputs.

11) Applicable for digital inputs.
