摘要： A data processing circuit includes a rewritable nonvolatile memory and a controller performing nonvolatile memory control and external interface control. A first detector and a second detector are employed to detect respectively whether the operation of the data processing circuit deviates from a first operating condition and a second operating condition, wherein the second operating condition is severer than the first operating condition. When the first detector detects deviation from the first operating condition, reset is instructed to the controller. When the second detector detects deviation from the second operating condition, the controller backs up an internal state and imposes a restriction on external access to a storage region of the nonvolatile memory. Accordingly, when operation of the microcontroller deviates from specific operating conditions within an operation guarantee range and performance degradation is exhibited, an unauthorized access to the data inside the microcontroller can be suppressed.
摘要翻译：数据处理电路包括可重写非易失性存储器和执行非易失性存储器控制和外部接口控制的控制器。采用第一检测器和第二检测器来检测数据处理电路的操作是否偏离第一操作条件和第二操作条件，其中第二操作条件比第一操作条件更严格。当第一检测器检测到与第一操作条件的偏差时，向控制器指示复位。当第二检测器检测到与第二操作条件的偏差时，控制器备份内部状态并对对非易失性存储器的存储区域的外部访问施加限制。因此，当微控制器的操作在操作保证范围内偏离特定操作条件并且表现出性能下降时，可以抑制对微控制器内的数据的未经授权的访问。

摘要： A mobile communication terminal device whose authentication and settlement functions by noncontact proximity communication can be continuously used even after operating voltage from battery power drops is provided. Only when the supply of required power from a battery is lost, a security controller is controlled into a mode in which it operates with low power consumption and noncontact authentication and settlement functions are ensured by external electromagnetic field power. Thus the noncontact authentication and settlement functions can be used even after the battery remaining capacity is lost by use of a communication function for the principal purpose. Specifically, the following is implemented: when there is the supply of required power from the battery, it is made possible to carry out high-performance, multifunctional authentication and settlement processing making good use of high-speed processing, mass storage, and the like which are the advantages of the security controller essentially driven by battery; and in an anomalous instance in which the battery remaining capacity is lost, it is made possible to carry out minimal authentication and settlement processing.

摘要： The invention facilitates to meet both of the mode of use that finds precedence in frequent rewrite to the nonvolatile memory and data retention during the power supply being cut off, and the mode of use that finds precedence in the data retention characteristic. The controller enables an information storage operation to the nonvolatile memory cells, by means of erase and write processing through boosting of the voltage applied to the nonvolatile memory cells and clamping of the boosted voltage, and performs a selection control that selects the application interval of the boosted voltage applied during the information storage operation and so forth. This selection control enables utilizing the nonvolatile memory cells as temporary rewrite areas, and facilitates to meet both of the mode of use that finds precedence in data retention during the power supply being cut off, and the mode of use that finds precedence in the data retention characteristic.
