摘要： A controller offers various security modes for protecting program code and data stored in memory and ensuring that the protection is effective during all normal operating conditions of the controller. The controller includes configuration settings that segment program memory into a boot segment, a secure segment and a general segment, each with a particular level of security including no enhanced protection. The boot code segment (BS) is the most secure and may be used to store a secure boot loader. The secure code segment (SS) is useful for storing proprietary algorithms from third parties, such as algorithms for separating ambient noise from speech in speech recognition applications. The general code segment (GS) has the least security. The controller is configured to prevent program flow changes that would result in program code stored in high security segments from being accessed by program code stored in lower security segments. In addition, the processor may be configured to have associated secure data portions of both program memory, such as flash memory, and random access memory (RAM) corresponding to the BS, SS and GS. Attempts to read data from or write data to the program memory or RAM associated with a higher security level from a lower security level are prevented from occurring.

摘要： A microcontroller and associated EPROM program memory are fabricated in a single semiconductor chip. The microcontroller device is adapted to be programmed using digital command words or other bit patterns applied as inputs after installation of the device in circuit with a system to be controlled by the device, and to have its programming pins isolated from the system to avoid effects on system operation while the programming is taking place. The in-circuit programming uses considerably less than the total number of input/output (I/O) pins of the device, which in total are fewer than the number of bits in a command word. This is achieved with a serial/parallel programming interface between the pins and the program memory, and by applying the data in serial fashion to the interface where it is latched and loaded in parallel in the memory. Input data to the device may alternatively be entered in parallel to the interface in bytes of width less than the total number of I/O pins of the device.

摘要： A semiconductor microcontroller includes the capability to perform analog to digital conversions of an analog signal representative of a variable parameter indicative of the need to exercise a control function. While the analog to digital conversions are being performed, the microcontroller processor can be placed in a sleep mode which eliminates noise arising from switching activities of the processor as a source of inaccuracy in the conversion process. At the end of the conversion, the analog to digital converter can either shut itself down or wake up the processor. Alternatively, the converter may shut itself down in response to a different user selected control signal.

摘要： A processor architecture scheme which allows for encoding multiple addressing modes and which has multiple sources for generating a bank address value. The processor architecture scheme has a Central Processing Unit (CPU) for executing an instruction set. A data memory is coupled to the CPU. The data memory is used for storing and transferring data to and from the CPU. The data memory is divided into a plurality of banks wherein one of the plurality of banks is a dedicated bank for general and special purpose registers. A selection circuit is coupled to the data memory. The selection circuit is used for selecting one of the multiple sources for generating the bank address value. A bank select register is coupled to the selection circuit. The bank select register is used for supplying a bank address value for an instruction to be executed in a direct short addressing mode. An instruction register is coupled to the selection circuit for supplying a bank address values for an instruction to be executed in a direct long addressing mode and for supplying a register address within a bank for the instruction to be executed in a direct short addressing mode.

摘要： A successive approximation register analog-to-digital converter (SAR ADC) having a sample, hold and convert amplifier circuit may be configured for either a single channel SAR ADC or a multiple channel SAR ADC. Switches or metal connection options, e.g., bit configurable or metal mask configurable, respectively, may be used to configure a common capacitor area, a portion of which may be used as a reconfigurable charge-redistribution digital-to-analog converter (CDAC) of the SAR ADC as either a single channel sample, hold and convert 12-bit capacitor configuration or a four channel sample, hold and convert 10-bit capacitor configuration. All other parts of the SAR ADC circuitry may be substantially the same for either configuration, e.g., the resistive digital-to-analog converter (RDAC), successive approximation register (SAR), ADC controller, sample, hold and convert switches, comparator, etc, may be substantially the same for either the single or multiple channel SAR ADC configurations.

摘要： A microcontroller fabricated on a semiconductor chip is adapted, when operating, to execute programs and instructions and, in response, to generate control signals to selectively control external apparatus. A clock generates timing signals to control the timing of the microcontroller execution and operation. An on-chip program memory has space avilable for storing a program to be executed by the microcontroller in sequential steps in successive address locations of the program memory. An instruction stored in unerasable memory on the chip initiates self-programming of the program memory with the program to be executed by the microcontroller by enabling a pointer timed by the clock to alternately read addresses containing steps of the program to be executed from off-chip memories and to write same into successive addresses of the on-chip program memory by incrementing the latter addresses with each step to be written therein.

摘要： A microcontroller is adapted, when operating, to execute programs and instructions and, in response, to generate control signals to selectively control external apparatus. The microcontroller includes a power supply for supplying power to the overall device within a predetermined range suitable for its operation, and a clock for supplying a clock frequency to the microcontroller with a stability suitable for precise timing and counting within the device. The microcontroller is selectively reset to prevent it from executing programs and instructions for purposes of generating the control signals, and is maintained in the reset condition despite initiation of a removal from the reset condition, until the power supplied by the power supply is in a predetermined range and the clock frequency supplied by the clock is stable. In this way, no execution by the microcontroller is permitted until device stability is achieved, to prevent errors in execution. In the disclosed embodiment, the reset condition is maintained by a power-up timer and an oscillator start-up timer, each timer having a programmable timeout interval to end the reset condition only when the timeout intervals of both timers have expired.
