FRAM Technology Applied to MCU System

While EEPROM and Flash are generally the non-volatile memory (NVM) of choice for most applications, ferroelectric RAM (FRAM) offers distinct advantages for many low-power designs in energy harvesting applications, such as wireless sensor nodes, Smart meters, and other data logging designs. With its extended write cycle endurance and data retention time, FRAM technology can help […]

Combining FPGA technology with MCU for a single-chip solution

Embedded designers spend a lot of time finding the right microcontroller (MCU) for the task at hand. Often, space is a constraint and the right mix of raw performance, I/O, memory resources, power consumption, and peripherals becomes the holy grail of finding the right fit. The search becomes more complicated if you have special logic […]

How to optimize the optical module through temperature control

Optical networks are the key to the development of broadband Internet services. The fibers that interconnect large switches can transmit gigabits of data per second, and improvements in photonic control are steadily increasing peak bandwidth. To maximize the fiber’s available bandwidth, manufacturers use dense wavelength-division multiplexing (DWDM), in which light of multiple colors is transmitted […]

MCU can choose any general serial interface such as SPI, I²C or UART

MCUs offer a very wide selection of serial interfaces. The choice of serial interface may be as simple as the interface required for the peripheral components, but when you can choose which interface to use, an informed decision can have a significant impact on system performance. General purpose serial interfaces like SPI, I²C or UART […]

Difference between I2C and SPI and its UART communication protocol

I2C, SPI, and UART are all common low-speed board-level communication protocols, At present, the mainstream SoCs have built-in controllers for these communication protocols. Similarly, various sensors, Touch controllers, fingerprint modules, Bluetooth modules, and WIFI modules are also compatible with one or more of these three communication methods. The differences between these three communication protocols can […]
