摘要： An integrated circuit device provides a choice of external pins (connections) that may be user selectable for coupling an external filter/stabilization capacitor to an internal voltage regulator. However, connecting the output of a internal voltage regulator to an uncharged external filter/stabilization capacitor (or to a capacitor charged to a different voltage level than the internal regulation voltage) through a low impedance path can cause the regulator output voltage to sag/spike if the internal voltage regulator tries to charge/discharge the capacitor up/down to equilibrium with the regulator output voltage. To minimize this potential sag/spike, the voltage on the external filter/stabilization capacitor may be adjusted in a controlled manner to substantially the same voltage as the voltage on the output of the internal voltage regulator, and then the internal voltage regulator is operationally coupled through a low impedance to the external regulator filter/stabilization capacitor.

摘要： An internal voltage regulator in an integrated circuit device is always active upon initial start-up and/or power-on-reset operations. The internal voltage regulator protects the low voltage core logic circuits of the integrated circuit device from excessively high voltages that may be present in a particular application. In addition, nonvolatile memory may be part of and operational with the low voltage core logic circuits for storing device operating parameters. Therefore, the internal voltage regulator also protects the low voltage nonvolatile memory from excessive high voltages. Once the integrated circuit device has stabilized and all logic circuits therein are fully function, a bit(s) in the nonvolatile memory may be read to determine if the internal voltage regulator should remain active, e.g., how power operation with a high voltage source, or be placed into a bypass mode for low power operation when the integrated circuit device is powered by a low voltage.
摘要翻译： 初始启动和/或上电复位操作时，集成电路器件中的内部稳压器始终有效。 内部电压调节器保护集成电路器件的低电压核心逻辑电路免受可能存在于特定应用中的过高的电压。 此外，非易失性存储器可以是用于存储设备操作参数的低压核心逻辑电路的一部分并且可操作。 因此，内部稳压器也可以保护低压非易失性存储器免受过高的高压。 一旦集成电路器件已经稳定并且其中的所有逻辑电路都完全功能，则可以读取非易失性存储器中的位以确定内部电压调节器是否应保持有效，例如，如何使用高电压源进行功率操作， 或者当集成电路器件由低电压供电时，将其置于旁路模式以进行低功耗操作。

摘要： A processor device has a data memory with a linear address space, the data memory being accessible through a plurality of memory banks. At least a subset of the memory banks are organized such that each memory bank of the subset has at least a first and second memory area, wherein no consecutive memory block is formed by the second memory areas of a plurality of consecutive memory banks.
