ABSTRACT:
Apparatus for detecting electrostatic discharge events that may affect operation of a calculator and for suspending the operation of an internal calculator chip before the discharge can corrupt the chip's operation. The apparatus includes an edge detector that detects the discharge event and generates a signal to timer circuitry. The timer circuitry in response generates a signal for a predetermined time to WAIT circuitry which suspends operation of the calculator chip before its calculations can be corrupted. The predetermined time is long enough for the electrostatic discharge to dissipate sufficiently so that it can no longer corrupt the calculations. After the predetermined time passes, the calculator chip resumes its operation to complete its calculations.
