MEC1310 NU Application Field and Working Principle

The MEC1310-NU (Nano ULP) is an integrated microcontroller and memory that can be used in a slew of embedded applications. It has become a popular choice for low power, small form factor, extremely efficient code execution and peripheral support in an ideal amount of I/O resources.

The nano ULP carries a 16-bit processors, better known as 486 compatible microprocessor. Conceived as an effortless form to accelerate their platform applications, developers can find in this microcontroller the source for a variety of purposes. Among the applications, vendors are able to conceive solutions for firewalls, VoIP solutions, POS applications & robotic solutions.

At its core, the MEC1310-NU utilizes a very powerful core, the 8051 that can be clocked up to 24MHz, allowing a wide range of operations to accelerate time to market for various applications. The chip contains a large number of general purpose I/O pins, with the majority of pins configured as digital I/O. It also has built in on-chip SRAM, ROM and Flash program memory. The on-chip ROM and flash can store up to 64KB of program code.

But even more impressive is the fact that the MEC1310-NU has a high speed, low power timer and fixed point arithmetic coprocessor, which allows the CPU to offload many of the mundane instructions and thereby freeing up the CPU to handle more complex instructions. Additionally, it provides plenty of I/O resources like an SPI port and an I2C port which provides the connection to peripheral devices and analog circuits.

Maybe one of the great features provided by this microcontroller, are the built-in power saving features. For example, the “Always On” feature allows the MCU to stay powered on even in the case of a system crash or a power failure. It also features a battery-backed RAM which preserves the data and program code even when the power is off. With this, system designers can be sure their MCU can remain safe from any power failure without requiring any external components.

The working principle of the MEC1310-NU is fairly straightforward. The core is connected to peripherals, memory and off chip memory by providing internal buses. These buses are used by the CPU to access data and instructions stored in the memory. The CPU then executes instructions, which control the peripherals and on-chip resources. The CPU also has access to a few other control lines like the interrupt line, which lets external events affect CPU operations.

Moreover, the MEC1310-NU has integrated advanced security features such as AES encryption and secure user authentication. With these tools, developers aim to fight against malicious applications and security threats. It is also capable of supporting third-party system designs, as well as being programmable via several industry standard interfaces like SPI, I2C, USB and UART.

To sum it up, the MEC1310-NU is a powerful and versatile MCU that can be used in a variety of embedded applications. It carries a 486 compatible CPU, plenty of I/O, and some nice features like always on and battery-backed RAM for improved system stability, AES encryption for security and support for multiple interfaces.
