摘要：A circuit and method for programming and control of an integrated circuitincludes a control pin receiving an applied input voltage selected from a set of
predetermined programming voltages and an on-chip control voltage decode circuit toselect one of multiple programming states for the integrated circuit based on the
applied input voltage. In one embodiment, an off-chip voltage divider is used to establishthe set of predetermined programming voltages. The on-chip control voltage decodecircuit includes a voltage divider to generate comparison voltage levels for detecting thevoltage level of the input voltage for selecting the desired programming state. Thecomparison voltage levels include voltages having voltage values that are midwaybetween pairs of adjacent programming voltages. The voltage decode circuit includes acontrol circuit receiving comparison results from comparators and generating an outputcontrol signal for selecting the desired digital state based on the comparison results.
