Abstract
A data processing apparatus supplied a first voltage from outside, includes a CPU, a first voltage generating circuit, a second voltage generating circuit, a clock generating circuit, and, a nonvolatile memory which can be accessed by the CPU. The first voltage generating circuit generates a second voltage, a voltage level of which is lower than that of the first voltage. The clock generating circuit is supplied the second voltage from the first voltage generating circuit and generates a clock signal, and the second voltage generating circuit is supplied the second voltage from the first voltage generating circuit and the clock signal from the clock generating circuit, and generates a second voltage, a voltage level of which is higher than that of the first voltage, for supplying to the nonvolatile memory.
