STR912FAZ47H6T application field and working principle

The STR912FAZ47H6T is an embedded microcontroller from STMicroelectronics. It is of the ARM926EJ-S family and incorporates several peripherals like USARTs, Flexible Static Memory Controller (FSMC), an Ethernet interface and a number of timers and interrupts. The microcontroller is typically used in network communication, data storage and industrial automation application.

The STR912FAZ47H6T is designed with a 16-bit data bus and can operate at up to 100MHz. It has a total of 16Kb of internal ROM storage and 64Kb of internal RAM storage. It is also equipped with 3 channels of I2C, 4 channels of SPI and 4 channels of UART.

The STR912FAZ47H6T provides power-saving support via a deep-sleep mode and low-voltage operation. It has an integrated real-time clock (RTC) which can be used for accurate timekeeping and/or for generating interrupts.

The STR912FAZ47H6T works using a von Neumann architecture, where the same memory space is used for both program and data instruction. This means that there is no separate memory for instructions and data. All the instructions and data are stored in the internal memory. The instructions are then read from the memory and executed one by one. The instructions will perform the specified tasks after being decoded by the CPU.

The STR912FAZ47H6T has two distinct modes of operation: the interrupt mode and the basic mode. In the interrupt mode, the device can be triggered by any activity occurring in other devices, like both user-programmed devices and external devices. The interrupt will cause the microcontroller to change its current instruction and execute a specific routine to handle the interrupt. In the basic mode, the microcontroller will execute instructions sequentially, one after the other.

The STR912FAZ47H6T microcontroller has become a popular choice for a variety of embedded applications due to its ease of use and reliable performance. Because of its simple architecture and wide range of peripheral interfaces, it is used in a wide range of applications, from consumer electronics to industrial automation systems. The device is used for providing reliable and highly flexible control for many embedded projects, including USB host/client functions, wireless communication, security and smart card applications.
