摘要： A microcontroller unit includes a processor for generating a first control signal to start a comatose mode of operation for the microcontroller unit. Control logic responsive to the first control signal generates an enable signal at a first level and the control logic is further responsive to a second control signal for generating the enable signal at a second level. A voltage regulator generates regulated voltage from an input voltage. The voltage regulator shuts down to provide a zero volt regulated voltage responsive to the enable signal at the first level and powers up to provide a regulated voltage at an operating level responsive to the enable signal at the second level.

摘要： A magnetic stripe card reader for reading a magnetic stripe on a card having at least one track of magnetically stored information stored thereon as a stream of encoded discrete data bits separated by bit times is disclosed. Aa magnetic head is provided for reading the magnetic pulses as the magnetic stripe is passed thereby to output a time varying analog signal. A data converter incorporated on an integrated circuit is then operable for converting the analog signal to a digital time series of digital values. A processor incorporated on the integrated circuit can ten process the digital output of the data converter and is operable to first determine potential bit boundaries and then recover timing information from the digital time series to discriminate the bit times between data bits. The value of each data bit is then determined during each bit time to provide a stream of extracted data bits.
