Hi, I need to implement a data logging device with a high-speed (480Mb/s) USB 2.0 to the host. I'm considering the Cypress EZ-USB FX2. Any one got any experience with this device ? Does it deliver ? Does the software driver work out of the box ?. Any feedback good or bad appreciated. Thanks

I am looking for a small low cost asynchronous dual port RAM. Cypress and IDT devices are too big and expensive. Is there anything smaller/cheaper? I need only 128 bits (16x8). Best regards

I'm new at working with USB and need some help with a design issue. My uC with USB functionality (Cypress PSoC CY8C24994) needs to operate on 3.3V but I am aware that the USB Vcc is traditionally 5V. PSoC Designer allows me to start up the uC in 3V USB operation mode, which effectively "disables voltage regulator and pass-through Vcc for pull-up", but does not indicate whether or not to ph...

Hi - I ran into PSOCs a little while ago - and I'm having trouble figuring out *what* exactly they are... Cypress calls it a "mixed signal array" - which is a term that I'm not very familiar with. They say it has a microcontroller, along with a number of configurable "elements" (that can be set to be ADCs, DAC, timers, PWM, etc.) But my understanding of a microcontroller is that it essen...

I am contemplating a design. The Cypress FX2 docs state that USB 2.0 buffers can be up to 512 bytes for bulk transfers. If USB 2.0 is only services every 125 uS then how do drives and other devices get closer to the ~60mB through put? Or even the 25mB average of drives? Thanks n

Hello, Does anyone has experience with the Cypress CY7C67300 USB chip. I want to read it by using the HPI protocol. I have a PCB with a C167 infineon microcontroller connected to this chip. I have tried but I can't get it working. Can anybody give me some hints. Jac.

Hi everyone, So I'm working on a new project where I want a web browser to a certain site to open whenever my USB device is plugged in and send some data. I plan on using a Cypress Encore chip and am looking over all the app notes and sample code but most of it just directly sends data like a mouse or keyboard. Is there a good resource on sending commands to a PC/Mac? Please let me know if you...

I have been led to believe tha PALCE devices are fuse (and everything else!) compatable with GAL devices. Is this correct? More specifically, can a JEDEC file aimed at a Cypress PALCE20V8 be programmed into a Lattice GAL20V8 without modification? Thanks in advance, Gary Partis

Hello, I'm trying to implement a simple communication link between my PC and the FPGA. Having read that an HID is the simplest form of USB communication, being a newbie in this, I decided to have a go at that (UART has been done, I figured I could use the challenge, silly me :). Problem's that the documentation for writing the firmware of the USB controller (Cypress CY7C67300/EZ-HOST) is ver...

I would like to use an FPGA for a motor control application. I have worked with FPGAs before and am comfortable with what needs to be done inside the FPGA, where I need some advice is how to interface the FPGA with the outside world. At the end of the chain I need to generate an analog command voltage (multiple channels actually). My initial idea was to use a Cypress PSOC as the DAC and talk ...

I'm currently looking at USB host chips from Atmel and Cypress. Has anyone had experience writing host side software using chips from either of these companies, and what were your experiences? Thanks. Lee Thalblum

I've purchased one already made by "Cypress Semiconductor" but it doesn't work. The VID is 04b4 and the PID is 5500. Can anyone suggest a USB to RS232 adapter that does its job perfectly 100% of the time under Microsoft Windows, i.e. it trully behaves exactly just like any other serial port?

Hi, Because of the FX1 from Cypress is hard to get for me at this place on earth, I was looking for an alternative and found a nice one: the MC68HC908JB8. I designed a little piece of hardware to develop and I'm looking for a code template now. I've searched the net, but I couldn't find much, or I have to buy the expensive USB08 board. Does anyone know where I can find a template or a...

Is there a GCC or any other open source C Compiler available for the Cypress PSoC? Not that $145 for the Image Craft PSoC Compiler is that expencive, but free means I don't have to get my bosses approval to start working with the PSoC. Thanks, Eric

Hi, I'm trying to read data from I/O port C on the FX2 development board into my computer and then immediately write the received data back onto port E using the CyAPI library. I'd like to be able to run this cycle of data transfer (IOC-> BulkInEndPt-> PC console application-> BulkOutEndPt-> IOE) at a few kHz, but so far I've had no luck. I'm using two 512 byte 4x buffered bulk endpoints. My TD_Pol

both free samples and 49$ starterkit available, my should be airborn right now somewhere between Paris and my place. The CPLD is small, 190MC, but it still much more then the 16MC availabel in ADI's ADuCs or ST's uPSD devices. PSoC 5, Cortex based devices will probably only be available next year Antti

Hi, It seems I can't find anything else than CY7C68013? With the plenty of USB 2.0 High speed devices around novadays (like cameras, audio, even flash disks) I do wonder what peoples do use?

Hi Guys, I have attempted to perform a USB Bulk read transfer over an EZ-USB FX2 development board. Vendor requests work fine, but using the usb_bulk_read() functions returns the following error message: "usb_submit_async: submitting request failed, win error: The parameter is incorrect" So far, we have established that the problem is on the peripheral (8051 FX2) side, and *not*...

I'm working with a Cypress PSoC micro with an M8C core (CY8C29666). I have 32K ROM and 1K RAM. I need to implement 1024 bit RSA encryption in as small a footprint as possible. I do not need to do any key generation in the micro itself. I know that RSA is common on Smart Card micros and secure micros with similar resorces, but I can't find any good examples. All I find is tons of M...
