FAQ

What is the maximum operating frequency of the UPD70F3417GC(A)-UEU-AX?

The UPD70F3417GC(A)-UEU-AX operates at a maximum CPU frequency of 40 MHz using its internal PLL with external crystal or ceramic resonator. This frequency is sustained across the full −40°C to +125°C temperature range when supplied within the 1.8–5.5 V specification. The UPD70F3417GC(A)-UEU-AX achieves 1.2 DMIPS/MHz, delivering 48 DMIPS total performance for real-time control tasks.

Does the UPD70F3417GC(A)-UEU-AX support CAN FD?

No, the UPD70F3417GC(A)-UEU-AX implements a classical CAN 2.0B controller compliant with ISO 11898-1, supporting bit rates up to 1 Mbps but not CAN FD features such as flexible data-rate or extended payload. Its CAN module includes 32 message objects, programmable timing registers, and automatic retransmission - sufficient for body electronics and chassis networks. UPD70F3417GC(A)-UEU-AX users requiring CAN FD must select newer Renesas RH850 or RA-family devices.

What debug interface does the UPD70F3417GC(A)-UEU-AX provide?

The UPD70F3417GC(A)-UEU-AX integrates a full-featured On-Chip Debug Unit (OCD) accessible via standard 5-pin JTAG interface (TCK, TMS, TDI, TDO, TRST). It supports real-time execution control, hardware breakpoints, register and memory inspection, and flash programming - all without halting peripheral operation. This debug capability is fully supported by Renesas E2 studio and CS+ development environments. UPD70F3417GC(A)-UEU-AX does not support SWD or cJTAG.

Is the UPD70F3417GC(A)-UEU-AX qualified for automotive applications?

Yes, the UPD70F3417GC(A)-UEU-AX is AEC-Q100 qualified (Grade 2: −40°C to +105°C ambient) and rated for automotive body electronics per Renesas' "Standard" quality grade classification. It meets stringent requirements for ESD immunity (±2 kV HBM), latch-up immunity, and long-term reliability under thermal cycling. While not ASIL-certified, UPD70F3417GC(A)-UEU-AX is widely deployed in door modules, seat controllers, and lighting ECUs where functional safety decomposition is handled at system level.

What is the flash endurance specification for the UPD70F3417GC(A)-UEU-AX?

The UPD70F3417GC(A)-UEU-AX specifies 100,000 write/erase cycles for its 512 KB on-chip flash memory, validated across the full operating temperature range. Each flash page is 128 bytes, and erase operations are performed per-page or per-block (8 KB). The UPD70F3417GC(A)-UEU-AX includes built-in ECC for single-bit error correction and detection of multi-bit errors - ensuring firmware integrity even after repeated field updates.
