The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. It is one of the most popular timing ICs due to its flexibility and price.
The RL78 was developed to address extremely low power but highly integrated microcontroller applications, to this end the core offered a novel low power mode of operation called “snooze mode” where the ADC or serial interface can be programmed to meet specific conditions to wake the device from the extreme low power STOP mode of 0.52uA.
The Intel 8253 PIT was the original timing device used on IBM PC compatibles.It used a 1.193182 MHz clock signal (one third of the color burst frequency used by NTSC, one twelfth of the system clock crystal oscillator, [1] therefore one quarter of the 4.77 MHz CPU clock) and contains three timers.
FreeRTOS provides methods for multiple threads or tasks, mutexes, semaphores and software timers. A tickless mode is provided for low power applications. Thread priorities are supported. FreeRTOS applications can be statically allocated, but objects can also be dynamically allocated with five schemes of memory management (allocation): allocate ...
In Shutoff mode, with 20–100 nA current consumption, depending on the product, applications have access to GPIO, reset, a real-time counter (RTC), and retention memory. The EFM32 family consists of several sub-families, ranging from the EFM32 Zero Gecko, [ 6 ] based on an ARM Cortex-M0+, [ 3 ] to the higher performing EFM32 Giant Gecko [ 7 ...
A special function register (SFR) is a register within a microcontroller that controls or monitors various aspects of the microcontroller's function. Depending on the processor architecture, this can include, but is not limited to: I/O and peripheral control (such as serial ports or general-purpose IOs) timers; stack pointer
A digital signal controller (DSC) is a hybrid of microcontrollers and digital signal processors (DSPs). Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although they can be programmed using the device's native assembly language.
Board can be cut into two separate boards: LPC-LINK board and target microcontroller board. Power input from 5 V via the USB cable or 5 V external power. If boards are separated, then 3.3 V external power is required for the target microcontroller board. Target microcontroller side: User LED. 12 MHz crystal. Prototype area.
