Welcome to the CAN-bus Wiki project

Cypress (Spansion / Fujitsu)

Spansion microcontrollers took over Fujitsu FMEA in 2013.

“Cypress is now Infineon” happened in 2020. Infineon acquired Cypress Semiconductor in deal valued at $10 billion.

On December 1st 2014 Spansion merged with Cypress. Cypress offered in the past controllers with CAN with its PSoC series. These controllers are added here.

Try to put the latest devices on top of each section and mark end-of-line products. Only specify the main parameters of the micro controllers and go more into deep with details about the CAN interface. Always try to put a link to the data sheet or manual.

Years age there was a short form catalogue of all Fujitsu CAN controllers available. Where is it now?

8 bit Controllers

  • PSoC 3 (Cypress) Single-Cycle 8051 core up to 67 MHz supplemented with programmable PLD-based logic.
    For CAN see the application note.

16 bit Controllers

Fujitsu offered many 16bit derivates.

32 bit Controllers

  • Feb/2015 Spansion announced Cortex®-M7 family

Traveo automotive MCU portfolio

The latest products, announced Jan 2016, enabling over-the-air (OTA) software upgrades. This is achieved by designing an MCU capable of talking to two separate, external flash memory units over a single HyperBus integrated in the MCU. While one flash memory unit retains the previous version of software, another will store new updates. If something goes wrong, you can always “roll back to the previous version,”.

  • Traveo™ S6J3100 family of ARM Cortex R5 based dual-core controllers @200 MHz. up to three CAN channels. Already CAN FD :-)
    • S6J311E/D/C/B , Traveo™ for Body, single ARM® Cortex-R5 and operates at 144 MHz, CAN controller: CAN-FD :-), Max 2 channel, CAN Clock Max 40MHz, 192 message buffers/channel, data bit rate max 5 Mbit/s
    • S6J331X Traveo™ for Cluster dedicated for car instrument applications, ARM Cortex®-R5 MCU running at 240MHz, 4MiB FLASH, MOST, Ethernet, six CAN-FD :-) channels, ISO26262 safety features,Clock Extension Peripheral Interface (CXPI)
    • S6J336X/337X Traveo™ for Cluster, Simple 2D Graphics ARM® Cortex®-R5 MCU running at 132MHz, four CAN-FD :-)
    • S6J351Cx Traveo™ for Body is targeted for body electronics applications, 132-MHz Cortex-R5 core, four channels (128 message boxes) of CAN-FD :-) interface for Body control applications.
