Abstract: An integrated device for adjusting dimming of LEDs includes a law memory storing a switching control law for LEDs. A modulated-clock generator coupled to an output of the law memory generates a modulated-clock signal having a parameter that varies according to the stored switching control law. A count stage coupled to an output of the modulated-clock generator generates a variable-frequency count signal. A comparator has an input coupled to an output of the count stage and compares the count signal with a setting value to generate a control signal for a LED channel that switches when the count signal reaches the setting value.

Abstract: Transmitter device including a modulator apparatus for the generation of a modulated digital signal in a remote control system. The modulated signal is defined by at least one characteristic quantity correlated to an information to transmit. The modulator apparatus is characterized by including a finite states machine for generating a modulating digital signal to combine with a carrier signal and obtain the modulated signal. The finite states machine generates the modulating signal on the basis of digital data corresponding to said at least one characteristic quantity.

Abstract: In order to manage, in the interrupt stage, a memory stack associated with a microcontroller according to a Program Counter signal and to a Condition Code Register signal that can be contained in respective registers, a first part of memory stack is provided which comprises a register for the Program Counter signal, and a second part of memory stack consisting of a bank of memory elements equal in number to the number of bits of the Condition Code Register signal for the number of the interrupts of the microcontroller. The two parts of stack are made to function in parallel by respective stack-pointer signals.

Abstract: A low area architecture for embedded programming flash memory portions in microcontrollers is based on substitution of the ROM/RAM/CORE functionality with a digital ISP controller implemented in a finite state machine and a standard interface. After connecting ports of the embedded programming flash memory portion and releasing a RESET pin, the microcontroller enters a particular operating mode and is managed by the digital ISP controller instead of the CORE. The ROM is not required to set up the microcontroller, and as a consequence, transfer of the boot program from the ROM to the RAM is not requested for subsequent execution.
