Intel’s MCS-51 Microcontroller Family – It’s Here to Stay
By Jon Wilder As I browse through many embedded electronics forums, I continue to see people making statements referencing Intel’s 8051 line of microcontrollers and how they are “obsolete”. However, nothing could be further from the truth. While Intel ceased production of the MCS-51 family in 2007, there are an abundance of manufacturers still making 8051-compliant microcontrollers […]

IoT from the ground up: MCUs and connectivity building blocks
In the emerging world of the Internet of Things (IoT), the tiny MCU is becoming the mighty MCU. But why and how does a device that has been around for decades figure into the ultra-low-power, connected, and still-unrealized world of the Internet of Things? And why is IoT connectivity any different from the connectivity we […]
Designing a Microprocessor from Scratch
By Val Gretchev, Electro-Tech-Online member Many students in Electrical Engineering learn how to use and program a microprocessor but very few know what goes on inside. This article will give the reader insight into the inner workings of a very simple microprocessor that can be extended to more powerful designs. I will use a visual […]

How To Monitor I2C Communications Through RS232
by Electro-Tech-Online member languer In the past when requiring to monitor I2C communications between two devices I would use a logic analyzer. Such monitoring was useful to determine if the I2C communications between devices was properly configured. Even though this is quite useful and efficient, it does require a logic analyzer, with an I2C protocol […]
ARM TechCon: High Energy Around Low-Power IoT
At ARM TechCon in Santa Clara last week, it was evident that the Internet of Things’ enormous potential understandably fuels the Internet of Things’ enormous hype. Still, IoT is “…growing slower than expected” and ARM apparently plans to jump-start growth with the mbed operating system (mbed OS) for low-power, embedded IoT devices. The full-stack OS, designed for ARM Cortex-M-based MCUs, is low-power […]
