Programmable System on Chip. This is a chip containing digital and/or analog blocks which can be configured to create a very wide range of designs. It may refer specifically to the Cypress Semiconductor's PSoC, which integrates configurable analog and digital peripheral functions, memory and a microcontroller on a single chip.

See http://www.cypress.com/psoc/ for information on Cypress' PSoC.

Mixed signal PCB layout for PSoC

I am developing a PCB for an analogue sensing application. It uses the internal ADC on a PSoC3. As usual, the application is very space constrained (11mm x 21mm), so I have had to make some compromises in the PCB layout which I would not have done…

What does "SoC bringup" mean?

Saw the term "expert in SoC bringup" on a job description for an embedded software developer: SoC here refers to System-on-Chip, but I was wondering what the term "SoC bringup" meant.

Why do TQFP and TFQN have different advice regarding analog ground?

This question is in reference to How to split Analog and Digital GND planes for a TQFN device. For the PSoC3, the advice on how to separate the analog and digital ground is different depending on the package. For the TQFP, it is suggested that the…

Capsense behind glass

Is it possible to make a capsense sensor that works through a sheet of glass? I have a working capsense sensor on one of these PSoC development boards: The buttons work fine, but when I put a sheet of glass on top, they don't work. Do I need to…

Am I over-complicating this data acquisition design?

I'm working on a project that involves periodically reading 16x 0~5V analog voltages from identical FSR voltage divider circuits using an ADC. Each FSR is connected to a gain/LPF stage before being read by an ADC. Each FSR's signal conditioning…

Unexpected resistance on breadboard

My first question on EE, please be kind. :-) I am trying to learn how the ADC works on this Cypress PSoC 4100 board. The circuit in the picture does nothing but power the board, connect it to the LCD display, and show the readings from the ADC. The…

What exactly is the use of PSoC?

Hey, yesterday I saw a demo (which was actually meant for my seniors) of a PSoC 5 board by cypress at my college. They demonstrated how to use the capsense built into the board and one of the PSoC chips to turn an LED on and off. This is basic Hello…

Programmable system on chip (SOC) pluggable on a host via PCIe

Does anyone know a COM which is put on a PCIe card, which has some flash memory, some RAM, JTAG support (or some kind of debugging support), some input ports like USB, perhaps support some output like via VGA or LVDS, just like this board:…

How do I calculate the supply current for a zynq 7010 chip?

I have a Zynq 7010 chip, and the current requirements in the datasheet confuse me a lot. Could someone explain how to determine how much current I'll need to supply to each…

PSoC as General Data Acquisition Block

I've been taking a close look at PSoC chips (series 1 in particular). With the reconfigurable analog blocks, they seem like a great solution for general data acquisition needs for prototype projects. I'm thinking about buying the programmer ($37…

GSM/3G SoC reverse engineering for GSM/3G Layer1/2 PacketAnalyzer

I want to develop a GSM/3G Packet Analyzer for study purposes, a somewhat more simplified version of OsmocomBB but without any TX modules. As some of you may know, even though OsmocomBB is open source, it has not been ported but to some very old…

How do I send accelerometer (ADXL335) signals (x, y and z) via xbee?

I want to send the signals from a 3 axis accelerometer (ADXL335) to a PSoC3 via Xbee modules (S2). What configurations do I need for each Xbees and can I send each of the signals (x, y and z) directly? If yes, then how? Would I need a separate…
