Application Field

SAX-XC878-16FFA 5V AC is an 8-bit RISC microcontroller developed by Semperit Technologies Corporation. It’s designed for embedded systems requiring low power and cost-sensitive applications. It is well suited for appliance control systems, security systems, lighting control systems, home networking systems, audio systems, industrial interfaces and more. Its typical applications include but are not limited to medical healthcare, industrial automation, energy conservation and smart cities.

Core Architecture

The SAX-XC878-16FFA 5V AC has a Harvard architecture and 8-bit microprocessor core. It also features a single register A coupled with a seven-bit program counter to provide maximum programming flexibility. The device has three operating modes which are user mode, supervisor (or protected) mode and external interrupt mode. In user mode, the microprocessor clock can run up to 16 MHz while in supervisor mode the clock runs at 8 MHz. The device also has two 16-bit timer/counters, a watchdog timer and 8-level priority interrupt controller.

Memory Architecture

The SAX-XC878-16FFA 5V AC is equipped with an integrated SRAM of 1K x 8-bit, a ROM of 16K x 8-bit and a FLASH of 64K x 8-bit. The SRAM is used for general-purpose data and program memory, the ROM for storing data, program and operating code, and the FLASH for program storage, code updating and data saving. It also has an internal 4KB RAM for storing parameters and user data.

Peripheral Features

The SAX-XC878-16FFA 5V AC offers multiple peripherals, including two SPI interfaces, two I2C interfaces, four UARTs, three 16-bit timer/counters, a PWM, four 8-bit general-purpose I/O ports, four 10-bit A/D converters, an analog comparator, and a temperature sensor. It also has an integrated 5V AC power supply and an integrated voltage regulator (IVR) to provide a stable operating voltage for all parts of the system. It offers various interfaces like I2S/PCM for audio applications and CAN for communication, making it a versatile device for many applications.

Working Principle

The SAX-XC878-16FFA 5V AC works on a simple principle. It has an internal clock that controls the sequence of instructions within the microprocessor. When a specific instruction is executed, the clock will counter the instruction until the next instruction is ready to run. The instructions are then fetched from the internal memory and the results of the instructions are stored back in the memory. The device is also capable of suspending instructions when external interrupts are encountered and can also be used to control external devices such as LEDs and motors.

Conclusion

In conclusion, the SAX-XC878-16FFA 5V AC microcontroller is suitable for many embedded applications due to its low cost and power consumption, ease of use and excellent performance. It can be used in many different applications, offering a versatile set of features. The device is equipped with powerful peripherals, integrated power supply and excellent EMI performance, making it an ideal choice for many applications. All in all, the SAX-XC878-16FFA 5V AC microcontroller is an excellent choice for embedded system designers who need an efficient and cost-effective solution.
