Celebrating 39 years
supplying all your CAN and Embedded Development Tool needs


CAN FD interfaces now available


The latest enhancement to the CAN standard is CAN FD in which the data segment of the CAN message is transmitted at up to 10 times faster than the 1Mbit rate of CAN 2.0B. 

For details of CAN FD see our Updated Tutorial

Both single and double CAN channel USB FD interfaces and PCI are now available from Peak.   See our CAN FD page


For "everyday use" our low cost CAN-USB 2.0B interface is now only £165.00


Peaks 120 page Catalogue of CAN interfaces, Modules and Software is available but be warned its a  24MBytes download

PEmicros ARM support includes more chips
and an ultra low price cable


The PEmicro USB Multilink ACP and the Cyclone ACP production FLASH programmer will now program the ATMEL SAMxxx, STM32, NXP M0,M3,M4, NXP/Freescale Kinetis (all), S32, TI-Stellaris LM3S,LM4,TM4C12xx, Infineon XMC4xxx, Maxim 716xx, Silicon Labs EFM32,SiM3, Cypress PSoC®4, Toshiba TX00,TX03,TX04 as well as a wide range of on and off chip SPI and off chip flash memories,

For users who want the cheapest Cortex debug cable USB Multilink ACP


With these features

Fast, hassle-free USB 2.0 communications interface

Draw power directly from the USB port – no external power supply needed

Multi-voltage support for targets ranging from 1.6 to 5.25 Volts

And now with faster links to both the PC and the target the Cyclone Universal FX  can speed up the production line and add extra security to your programming process. ......... For more details of this product see Cyclone Universal FX



CPU Support and features are as for the Cyclone Universal with the following enhancements :-

  • USB 2.0 link now supports "High-speed" protocol (up to 480Mb/sec link to the PC).

  • 1 Gbyte internal memory, no practical limit to # of images held.

  • SDHC Port for even more space.

  • For most recent CPUs ( e.g. Cortex M0-4, Qorivva, HC16/683xx, Coldfire  and MPC5xx/8xx ) a variant of the communication link to the target is provided that increases the download speed to a max of 25Mb/sec giving up to 5 x faster download of data.

  • Additional security features include ensuring that if you outsource your production no one can "run off a few units" without you knowing.

USB Universal On Chip Debugging Interface


The USB Multilink Universal  On-Chip-Debugging cable supports most NXP/Freescale chips and with suitable software can be used for Flash Programming and Debugging embedded target systems. It works with JTAG, SWD and BDM On-Chip-Debugging protocols.

If you are unfamiliar with the use of "On-Chip-Debugging" we have a short tutorial

It support these NXP/Freescale architectures:-   Cortex M4 (see above) , Kinetis  (JTAG and SWD),  ColdFire V1, +V1 and  V2 - 4 , Qorivva MPC55xx/56xx/57xx, HC(S)12(X), S12Z, HCS08, RS08 and DSC series.

Includes are ribbon cables for all supported architectures

Fast, hassle-free USB 2.0 communications interface

Draw their power directly from the USB port – no external power supply needed

Multi-voltage support for targets ranging from 1.6 to 5.25 Volts

Auto-frequency detection for HC(S)12(X), HCS08 + trimming capabilities for HCS08 devices.

Generates programming voltage on RESET line for RS08 devices.

For more details.

Aside from supporting a wider range of chips ( add 68K,HC16, PX & PPC 5xx/8xx) a major attraction of the Universal FX version is that for Synchronous architectures such as the Kinetis,  Qorivva,  Coldfire V2-V4, 683xx, HC16, Power Architecture PX Series and the DSC the communications can run at 4 to 10 times faster than the older Multilink interfaces giving faster downloading of code and uploading of debug information.

CLICK Embedded Tutorials

Do you need to quickly become knowledgeable about a CPU family or Embedded USB, CAN or TCP/IP or On-Chip Debugging ?
If so we have prepared a series of short Technology Tasters to get you up to speed with the Micros, Standards and jargon.  We hope you will find them informative.

For each Microprocessor chip family (over 100 are listed) our Supported Chips Directory shows all the software and hardware available for developing applications for that family.


Price is always part of any engineering decision so we have always tried to publish prices along with our technical literature. Those items which are normally supplied from stock have their price held on our web shop - you can move back and forward to look at technical information without loosing the contents of your shopping basket. The prices shown on the web shop are for cash with order purchase within the UK for a wide range of products that are normally available for same/next day ship following day delivery or at worst on a 5 to 10 day turnaround and the web site prices do not include VAT (20%) or shipping.  Prices shown on the web site that are sourced from companies in the EU and US may regrettably be out of date given the fast moving exchange rate variations of the current economic climate - call for up to date prices.

 Prices for international purchases are essentially the same but additional costs must be covered and theUCC paperwork is more complex. Follow this link for details of  International Purchase conditions.  The Universal Currency Converter™ comes to you by kind permission of those nice people at Xenon Laboratories. It is supplied as a guide to exchange rates and neither Xenon nor Computer Solutions make any guarantees as to it's accuracy.
