STR912FAZ47H6 is an advanced 16/32-bit microcontroller with sophisticated microprocessor, memory, and communication peripherals aimed at embedded applications such as industrial control, medical, home automation, and automotive. It is based on an ARM9E-S Core coupled with an advanced clock management unit and a variety of peripherals that enable fast, low-power control of real-time events.

STR912FAZ47H6 features a highly integrated architecture that integrates many of the most commonly used functions into a single chip. This reduces system size and complexity and increases reliability. The processor consists of the ARM9E-S Core, a tight-coupled on-chip memory controller, a Flash memory controller, and several on-chip peripherals, such as a 10/100Mbit/s Ethernet MAC, a USB 2.0 Host/Device/OTG Controller and a Storage/ATA controller. These integrated peripherals enable applications such as home automation, automotive, and industrial automation.

The ARM9E-S Core is a 32-bit RISC processor capable of executing Thumb instructions at up to 75MHz and providing load/store instructions with a pipeline depth of 5. The Core also features an ARM-proprietary Error Detection and Correction (EDAC) for faster detection of errors in memory, instruction, interrupt and data buses. In addition, the Core is also equipped with an on-chip memory protection unit (MPU) for efficient address checking.

The STR912FAZ47H6 also features a tightly integrated memory controller for direct access to on-chip SRAM memory and Flash memory. The memory controller provides access to both instruction and data memories, enabling the processor to access memory contents directly without incurring any additional cycles. This eliminates the need for additional software overhead and improves system performance. The memory controller also supports various interrupt priorities, error correction and detection, and power management functions.

The STR912FAZ47H6 has several communication peripherals that enable a variety of sophisticated embedded applications. These peripherals include a 10/100Mbit/s Ethernet MAC, a USB 2.0 Host/Device/OTG Controller, a CAN bus controller, a smart card interface, and a storage/ATA controller. These peripherals provide data transfer capabilities to devices such as printers, scanners, and peripherals that use the USB or CAN bus.

The working principle of the STR912FAZ47H6 is based on the ARM9E-S Core, which is responsible for controlling the system’s peripherals. The Core handles instruction fetching, instruction decoding, instruction execution, memory access, and interrupt handling. The Core can fetch instructions at a rate of up to 75MHz and store data in a two-level cache structure. The Core is also responsible for signal handling, power management (including low-power modes) and system initialization.

The peripherals are controlled by the Core and interact with it through peripheral registers. As the processor executes instructions, it accesses these peripherals to perform the desired operations. For example, when a peripheral needs to access the data bus, it sends a request to the Core which then initiates the bus cycle. The data is then transferred over the bus and the peripheral can access it.

The STR912FAZ47H6 has wide ranging application in embedded designs due to its flexible architecture and highly advanced peripheral set. As an example, the STR912FAZ47H6 can be used for motor control applications due to its advanced features such as the Memory Management Unit, which enables range checking and logical addressing. The processor’s on-chip communications peripherals can be used to connect to the outside world, enabling the device to be connected to any type of peripheral or data source. Other examples of applications include home automation, industrial control and automotive applications.
