Working Principle

The L138-FI-236-RL works by executing instructions from the program RAM, stored in the embedded flash memory. In each instruction cycle, the controller fetches the next instruction from memory, decodes the instruction, and executes it. The core of the L138-FI-236-RL integrates a number of components in order to be able to execute instructions and access data in the most efficient and least energy consuming way.

The core of the L138-FI-236-RL includes an ARM Cortex-M3 processor with separate code and data memory buses. This microcontroller has four levels of instruction cache, allowing the processor to access instructions faster than with a single level of cache. It also includes an instruction prefetch unit, which further reduces access time.

The processor core also includes an instruction memory management unit (IMMU), which monitors the instruction execution and prevents the processor from accessing invalid instructions. It also includes an instruction processor, which translates the instructions into a form that can be understood and executed by the processor core.

The L138-FI-236-RL also integrates a number of peripherals and interfaces to provide easy access to external devices. These include a USB 2.0 controller, an SPI controller, an I2C controller, an 11-bit A/D converter, four PLLs, and a 12-bit D/A converter.

In order to maximize efficiency, the L138-FI-236-RL is equipped with a range of power-saving features. These include a low-power mode and a reset management unit, which enable the controller to operate in a low-power state while executing a given instruction. Additionally, the controller integrates a number of power control registers, allowing the user to control the power consumption of specific peripherals.

Conclusion

The L138-FI-236-RL is a highly capable microcontroller that can be used in a variety of applications. It offers users a range of features and peripherals in order to reduce development costs and accelerate time-to-market. In addition, its low-power operation makes it a great choice for portable electronic equipment or embedded systems.
