Working Principle
The R5F521A6BDFN#V0 microcontroller is based on the H8/300OP core, which is an 8-bit microcontroller optimized for high-speed operation and low power consumption. The device is equipped with 1K x 16 bit on-chip read-only-memory (ROM) and 256 x 8 bit static RAM (SRAM) to provide storage space for program code and data. This on-chip memory is accessible through an external bus and is divided into a series of memory segments.
The on-chip peripheral functions of the R5F521A6BDFN#V0 are controlled by program instructions. These instructions are typically written in assembly or C language and are then compiled into machine language. The compiled program code is then loaded into the on-chip ROM and SRAM for execution. The microcontroller is designed to operate at clock speeds ranging from 8MHz to 32MHz.
The R5F521A6BDFN#V0 microcontroller supports a wide range of external interfaces, including two 8-bit A/D converters with up to 8-bit resolution, two USART channels, one SPI/I2C interface, and two 32-bit counter/timers.
