Does the UPD70F3825GB-GAH-AX support CAN FD?
No, the UPD70F3825GB-GAH-AX implements two CAN 2.0B controllers only, compliant with ISO 11898-1:2003. It does not support CAN FD frame format, bit rate switching, or extended data length. For CAN FD capability, Renesas recommends the RX72M or RA6T2 families instead of the UPD70F3825GB-GAH-AX.
Is the UPD70F3825GB-GAH-AX AEC-Q100 qualified?
Yes, the UPD70F3825GB-GAH-AX is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient, +125°C junction), with full test reports covering HTOL, TC, ESD, and AC/DC parametric validation. This qualification applies specifically to the GB-GAH-AX variant and is documented in Renesas' Automotive Reliability Report QZ-2013-001.
What debug interface does the UPD70F3825GB-GAH-AX provide?
The UPD70F3825GB-GAH-AX features IEEE 1149.1 JTAG interface supporting full boundary-scan, real-time trace buffer, and non-intrusive debugging. It is compatible with Renesas E2 emulator and third-party tools supporting V850ES architecture, enabling breakpoints, register inspection, and Flash programming without halting peripheral operation.
How much user-accessible RAM does the UPD70F3825GB-GAH-AX have?
UPD70F3825GB-GAH-AX provides 48 KB of on-chip SRAM mapped to address range 0x0000_0000–0x0000_BFFF, all accessible as general-purpose RAM for stack, heap, and data buffers. No portion is reserved for system use; the entire 48 KB is available to firmware unless explicitly allocated for peripheral buffers such as CAN message RAM.
