Embedded microcontrollers are widely used in a large number of situations, such as devices that require smart energy management. To simplify and make the development of these applications straightforward, NXP Semiconductors has released the SAF-XE164FM-48F80L AA microcontroller. This device is a cost-effective, yet full-featured solution that is suitable for various applications. In this article, we will explore the application fields and working principles of the SAF-XE164FM-48F80L AA.

Designed with a high integration vector-floating-point co-processor, the SAF-XE164FM-48F80L AA supports an operating frequency of up to 120MHz, with an up to 8KB of program code. Furthermore, it has 16KB of on-chip SRAM available for temporal variables. The microcontroller’s on-chip 4KB ROM contains the main data for booting the device and for downloading the application code.

Despite its relatively low cost and small size, the SAF-XE164FM-48F80L AA includes all the features necessary for a wide range of embedded applications. On top of the vector-floating-point co-processor, it has also an extensive peripheral list that includes two multi-purpose timers, two capture compare modules, 2 CANs, 2 eSCIs, 16-channel 10-bit ADC, an on-chip debugging block and up to 115 programmable I/O pins.

Given all these features, the SAF-XE164FM-48F80L AA is well-suited for a variety of embedded applications, such as motor control and power management. It is also used in such areas as HVAC, industrial automation and print imaging. Due to its integrated eXtreme Low-Power (XLP) technology, the microcontroller has outstandingly low current consumption, allowing it to maintain operation even in harsh environments and extreme battery conditions.

The working principles of the SAF-XE164FM-48F80L AA are quite straightforward. A set of instructions is loaded from an external memory into the microcontroller’s on-chip memory. Then, the instructions are executed one at a time. During the execution, several registers are used to temporary store the program’s variables and arithmetic/logic operations.

Once an instruction is completed, the values of the registers are updated and it moves to the next instruction. The process continues until all instructions are executed, or until an unrecoverable error occurs. The microcontroller then signals its state by sending commands to connected devices and by changing the states of its I/O pins.

In conclusion, the SAF-XE164FM-48F80L AA is a cost-effective, yet full-featured embedded microcontroller solution suited for a wide range of applications such as motor control, HVAC, industrial automation and power management. Its instruction set is easy to understand and its eXtreme Low-Power technology makes it a perfect choice for applications in harsh and extreme environments.
