Also known as a SOC, it is another name for a silicon chip which has a high degree of integration. Named principally because it incorporates devices like a uProcessor and a modem and a memory controller that might of at one time been separate chips on a PCB.

microcontroller vs. System on chip
I am starting out programming micro controllers and I was reading some documentation and textbooks. I am a little confused as to what the difference is between a Micro-controller and a System on chip?
Some documentation use these two terms inter…

One large microcontroller, or lots of small microcontrollers?
I'm used to doing basic and straightforward things with microcontrollers, relatively speaking. Things such as driving LEDs, running motors, basic routines, GUIs on character LCDs, and so on, but always just one key task with at most a few little…

Low power radio + microcontroller recommendation?
I'm searching for a low power system-on-chip that combines:
A processor (any achitecture)
A radio (any frequency/bitrate/tx power)
2 or more I/O pins (ADC would be a bonus)
Can anyone recommend a device?
Which chip companies should I be looking…

what really are: Microcontroller (uC), System on Chip (SoC), and Digital Signal Processor (DSP)?
The actual question is at the end. But reading that alone might not show you why am I confused. I wrote this post starting with some definitions, assumptions, and speculations and then asking the actual question.
I always think that I know the…

Is it common for internal pull-up resistors to fail? or what would cause them to become intermittent?
I have a board based on an ASIC ARM Cortex-M3 that after months of work suddenly started to report spurious button presses. The ASIC is not our design, but a reputable company's.
The buttons schematic is given below. The pin is configured as input…

Why can't I find SOCs with integrated memory?
I am looking for SOCs with integrated memory to avoid having to worry about design of a memory bus for, what is supposed to be, a pretty low power application. I'm looking for something like the raspberry pi where the ARM core and the memory are…

How do hybrid electronic systems work?
In hybrid systems, we can have DSPs, FPGAs, General purpose processors, etc on the same system operating together on the same application. How are the tasks distributed among them, and which unit manages this?

Where can I find an 8086 chip?
sometime ago I built an emulator for the 8086 chip and now I'm wanting to actually own one and set one up for some bit banging and such. Note, I'm not interested in all the PC specifics(DMA, PIC, BIOS, etc) only the bare basics to get the 8086 to…

Reducing chip count for an ARM embedded system
It seems like a lot of devices use an ARM SoC + a RAM chip + a flash storage chip. In applications that are very space-constrained, such as ChromeCast dongles, micro drones, or wristbands, it would be very useful to combine these 3 chips into 1 or…
