The AT90SCR100H-ALR microcontroller is an 8-bit microcontroller device developed and produced by Atmel Corporation. Its core technologies include single-chip real-time clock technology, low power consumption technology, timing and control mode and so on. Integrated with up to 4 16-bit timer/counters, 4 UARTs, SPI, I2C, CAN and LIN, 8/16-bit A/D converters and a Pulse Width Modulation module, the microcontroller is widely used in numerous embedded control applications such as automotive, consumer, industrial, instrumentation, medical, wireless and other industries.The working principle of the AT90SCR100H-ALR microcontroller is based on the AVR architecture which uses a Harvard type architecture in which instruction and data are separately transferred between the two major bus lines. It operates on a single cycle basis with each instruction taking only one clock cycle and each data read/write operation taking the same number of cycles. In addition, the microcontroller is based on AVR RISC instruction set which simplifies the program logic and makes complex operations easier to execute. Furthermore, the memory protection unit (MPU) is adopted to prevent program data and stack pointer from accessing memory regions beyond its limit and a watchdog timer is integrated to enable the device to reset itself when it gets stuck in a faulty state.In terms of power-saving, the AT90SCR100H-ALR microcontroller provides a power management unit (PMU) and an external clock. The PMU helps save power by controlling the system activities while the external clock ensures minimum power consumption by selecting the lowest possible clock frequency. Its tiny size and low power consumption make it suitable for battery-powered systems. In addition, it features configurable register arrays, intuitive programming interfaces and debugging circuit which allow for high-efficiency system design.In conclusion, the AT90SCR100H-ALR microcontroller is an ideal choice for embedded control applications due to its high performance, tiny size and low power consumption. Its wide range of communication interface options, configurable register arrays, intuitive programming interfaces and debugging circuit, make it an ideal choice for all kinds of embedded control applications. Its on-chip debugging circuit and breakpoint controller can support both on-chip and off-chip debugging. Moreover, the array of peripherals and its flexibility in programming add to its attractive features. Its low power consumption also makes it suitable for battery-powered systems.
