Introduction

The SPC5668GF1AVMGR is an embedded microcontroller from STMicroelectronics. It is a high-performance 8-bit MCU based on the Atmel® 8-bit AVR ATxmega®A1U family. It features an extended operating temperature range from -40 °C to +85 °C and an operating voltage from 2.7V to 5.5V. Furthermore, this microcontroller offers up to 128KB of programmable flash memory, 16KB of SRAM, and 512KB of RC oscillator.

Application Fields

SPC5668GF1AVMGR’s flexible and low-power architecture is widely used in various embedded systems to facilitate their operation, such as motor control and management, home appliances, HVAC systems, energy management, automotive, etc. It can provide efficient operation with low power consumption, due to its low-voltage operation range and low current draw, which helps to reduce system costs. With a 64-pin QFN package and up to 32 GPIO pins, it provides multiple software development tools such as C, C++ and several types of assembly. There are also multiple interfaces including an in-circuit serial programming (ICSP) interface, an integrated JTAG interface, and an object code uploader for easy development and debugging.

Working Principle

The SPC5668GF1AVMGR is based on a modified Harvard architecture, where program and data memories are separate. The microcontroller contains three buses, each with distinct roles. The instruction bus retrieves instructions from the program memory, stores them in the instruction queue and sends them to the CPU for execution. This bus is bidirectional, allowing internal components to communicate with the external interface.The data bus allows data transfer between peripherals and the CPU. It is bidirectional, with different timing parameters for transmitting, receiving and refresh cycles.The address bus is used for transferring addresses from the CPU to external interfaces and for selecting memory locations. It is also bidirectional, and can also be used for external communications with the help of the address decoder.

Conclusion

The SPC5668GF1AVMGR is an efficient and low-power embedded microcontroller developed by STMicroelectronics. It is designed to provide multiple interfaces and a wide range of memory capacities. It is suitable for use in a wide variety of applications, including motor control and management, home appliances, HVAC systems, energy management, automotive, etc. Its architecture based on a modified Harvard architecture, with distinct instruction, data and address buses forming its core, provide efficient and low-power operation.
