摘要： A card device has a regulator (5), a first internal circuit (6) and a second internal circuit (7), and the regulator supplies, to the second internal circuit, an internal voltage generated by dropping an external voltage (VCC) when the external voltage is high, and exactly supplies the external voltage as the internal voltage to the second internal circuit when the external voltage is low, and the external voltage is supplied as an operating power source to the first internal circuit and a transition to a low consumed power state is carried out if a command is not input for a certain period. The card device stops the operation of the regulator and suppresses the supply of the internal voltage to the second internal circuit in the transition to the low consumed power state. In the low consumed power state, consequently, it is possible to suppress a power consumption in each of the regulator and the second internal circuit in the card device.

摘要： A memory card and a microcomputer with nonvolatile memory wherein operation under two different types of power supply specifications is achieved are provided.A MultiMediaCard includes a flash memory and a controller which controls the operation associated with the flash memory. When the controller judges the level of supply voltage supplied from host equipment, it operates as follows: the controller judges whether detecting point corresponding to the voltage level of 1.8V system has been exceeded. After the judgment of excess, the controller judges whether detecting point corresponding to the voltage level of 3.3V system has been exceeded. When the supply voltage is at the voltage level of 1.8V system, the controller causes the flash memory to operate in the 1.8V-system operation mode without driving regulators or level shifters. When the supply voltage is at the voltage level of 3.3V system, the controller drives the regulators and the level shifters to convert the voltage level and causes the flash memory to operate in the 3.3V-system operation mode.

摘要： Whether an initial command outputted from a host is ‘CMD1’ or ‘CMD55+CMD41’ is detected with an initial command detection portion 8, and the result of detection is set in an SD/MMC register 13. Reset process for hardware and that for firmware are carried out based on the result of detection set in the SD/MMC register 13. Thereafter, a microcomputer 7 sets data indicating in which mode, MultiMedia Card mode or SD mode, the firmware reset process was carried out, in a F/W process SD/MMC register 14. A H/W-F/W mode comparison circuit 15 compares data in the SD/MMC register 13 with data in the F/W process SD/MMC register 14. If these data agree with each other, busy state is released, and command wait state is established. If they disagree with each other, a disagreement occurrence detection signal is outputted to the microcomputer 7, and power-on reset processing is performed again.
