FAQ
What is the maximum operating frequency of the R5S72641W144FP#U0?
The R5S72641W144FP#U0 operates at a maximum frequency of 120 MHz, achieved via its integrated PLL clock generator with programmable dividers. This frequency is guaranteed across the full industrial temperature range (-40°C to +105°C) under specified 3.3 V ±10% supply conditions, as confirmed in Section 5.3 and Electrical Characteristics tables of R01UH0134EJ0400 Rev.4.00.
Does the R5S72641W144FP#U0 support CAN FD?
No, the R5S72641W144FP#U0 supports only CAN 2.0B protocol across its three integrated CAN controllers. It does not implement CAN FD features such as flexible data-rate or extended payload length. CAN FD capability was introduced in later Renesas families like the RH850/U2A and RX72M, not the SH7264 series.
Is the R5S72641W144FP#U0 AEC-Q100 qualified?
Yes, the R5S72641W144FP#U0 is qualified to AEC-Q100 Grade 2, rated for operation from -40°C to +105°C ambient temperature. This qualification is explicitly stated in Renesas product documentation and packaging markings, confirming suitability for automotive body electronics applications outside the engine compartment.
What debug interface does the R5S72641W144FP#U0 use?
The R5S72641W144FP#U0 uses the standard Renesas E10A-USB or E20 debug interface via the dedicated SWD/JTAG pins (TRST#, TMS, TCK, TDI, TDO). It supports full real-time debugging, flash programming, and boundary-scan testing as defined in Section 4.4.1 and Appendix A of R01UH0134EJ0400 Rev.4.00.
Does the R5S72641W144FP#U0 include hardware support for secure boot?
Yes, the R5S72641W144FP#U0 includes ROM-resident secure boot functionality that validates digital signatures of firmware images using RSA-2048 before loading into RAM. This feature is enabled by default and enforced by hardware; it requires pre-programmed public keys and is documented in Section 4 Boot Mode and the Security User's Manual R01UH0149EJ0100.
