FAQ
What is the maximum operating frequency of the UPD70F3575GKA2-GAK-AX?
The UPD70F3575GKA2-GAK-AX operates at a maximum CPU frequency of 40 MHz when driven by its on-chip PLL with an external 20 MHz crystal. This frequency is sustained across the full −40°C to +125°C temperature range and 3.0–3.6 V supply, as validated in Renesas' electrical specifications (R01UH0114ED0200 Rev. 2.00, Section 20). The UPD70F3575GKA2-GAK-AX maintains timing compliance without derating in automotive under-hood conditions.
Does the UPD70F3575GKA2-GAK-AX support CAN FD?
No, the UPD70F3575GKA2-GAK-AX integrates two CAN 2.0B controllers compliant with ISO 11898-1:2003, supporting data rates up to 1 Mbps and standard/extended frame formats. It does not implement CAN FD protocol features such as flexible data-rate switching or extended payload length. For CAN FD capability, Renesas recommends the RH850/F1L series, e.g., R7F7015833AFP-C. The UPD70F3575GKA2-GAK-AX remains fully compatible with legacy CAN 2.0B networks used in current automotive platforms.
How much back-up RAM (BURAM) does the UPD70F3575GKA2-GAK-AX include?
The UPD70F3575GKA2-GAK-AX includes 2 KB of dedicated back-up RAM (BURAM), accessible only in stop mode and protected by independent power gating. This memory retains critical data - such as fault codes, calibration offsets, and security keys - during deep-sleep states or main power loss, without requiring external capacitors or batteries. The UPD70F3575GKA2-GAK-AX BURAM is mapped to a fixed address space and supports byte/word access with hardware write protection.
Is the UPD70F3575GKA2-GAK-AX qualified to AEC-Q100 standards?
Yes, the UPD70F3575GKA2-GAK-AX is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient) per Renesas' product documentation and ordering information. While the device operates up to +125°C junction temperature and is widely deployed in under-hood applications, formal AEC-Q100 certification covers Grade 2. Customers requiring Grade 1 (−40°C to +125°C ambient) should consult Renesas' latest qualification reports or consider the RH850/F1L family. The UPD70F3575GKA2-GAK-AX meets all stress-test requirements defined in AEC-Q100 Rev. G.
What debug interface does the UPD70F3575GKA2-GAK-AX support?
The UPD70F3575GKA2-GAK-AX supports on-chip debugging via the JTAG interface (IEEE 1149.1 compliant) with OCD (On-Chip Debug) functionality, including breakpoints, watchpoints, and real-time trace. It also supports serial-wire debug (SWD) mode through dedicated pins. Debug access requires the Renesas E2 emulator or compatible tools. The UPD70F3575GKA2-GAK-AX does not support SWD-only operation - JTAG pins must be routed for full debug capability, as specified in Section 3.7 of R01UH0114ED0200 Rev. 2.00.
