The AT90SCR100LHS-Z1T is a microcontroller manufactured by Atmel Corp, which fits into the category of embedded microcontrollers. The AT90SCR100LHS-Z1T is a low-power, low-voltage microcontroller intended for use in battery-operated and power-sensitive applications. It has an OTP (one-time programmable) memory and its low-voltage operations are suitable for battery-powered devices where maintenance and repair are difficult.

The AT90SCR100LHS-Z1T microcontroller has several applications, the most common being in consumer electronics, such as digital cameras, mobile phones, and handheld gaming devices. It is also used in automobile applications, such as intelligent lighting systems and keyless entry. Additionally, it is used for industrial applications such as process control, data acquisition, and motors. Since the AT90SCR100LHS-Z1T is an 8-bit microcontroller with 6KB of ROM, it can also be used for small embedded control projects.

The working principle of the AT90SCR100LHS-Z1T microcontroller is fairly straightforward. The AT90SCR100LHS-Z1T consists of the CPU (central processing unit), ROM (read-only memory) and RAM (random access memory) which stores instructions and data used by the CPU to perform various tasks. There is also a Program Counter which manages the sequence of instructions that are executed by the CPU. Additionally, the AT90SCR100LHS-Z1T also has several peripherals on board, including an 8-channel 10-bit analog-to-digital converter, a 6-channel 12-bit pulse width modulator, and up to 16 I/O lines.

The AT90SCR100LHS-Z1T microcontroller operates in two different modes. The first is the Active mode, which is used when the microcontroller is active and executing instructions. The other mode is the Idle mode, which is used when the microcontroller is idle and not executing instructions. The transition between these two modes is determined by the internal Power Management Unit (PMU).

In the Active mode, the PMU is responsible for managing the power supply and controlling the device’s clock speed. This creates a balance between having sufficient performance, while also maintaining low power consumption. In order to reduce the power consumption of the device in this mode, the clock speed is dynamically adjusted according to the application requirements. Additionally, the PMU is also responsible for providing the microcontroller with an operating voltage that it can operate on.

In the Idle mode, the PMU is responsible for throttling down the processor’s clock speed in order to reduce power consumption. It also turns off some of the device’s peripherals in order to reduce power consumption further. This mode is especially beneficial for battery-operated devices, since it allows them to achieve a long battery life without sacrificing performance.

The AT90SCR100LHS-Z1T microcontroller offers an excellent solution for battery-operated or power-sensitive applications. It is highly efficient and has a wide range of features that make it suitable for a variety of applications. Its low power consumption and flexible memory makes it an ideal choice for many embedded projects.
