FAQ
What is the maximum operating frequency of the UPD70F3767GF-GAT-M1-AX?
The UPD70F3767GF-GAT-M1-AX operates at a maximum frequency of 40 MHz, achieved using its on-chip PLL with configurable multiplication factor. This frequency enables deterministic execution of real-time tasks such as CAN message processing and PWM generation with sub-microsecond timing resolution. The device maintains full functionality across its specified temperature range (−40°C to +125°C) at this speed.
Does the UPD70F3767GF-GAT-M1-AX support CAN FD?
No, the UPD70F3767GF-GAT-M1-AX implements two CAN 2.0B controllers compliant with ISO 11898-1:2003, supporting bit rates up to 1 Mbps. It does not support CAN FD frame format, arbitration bit rate switching, or enhanced data field length. For CAN FD requirements, Renesas recommends migrating to RX72N or RA6T2 series MCUs, which include native CAN FD peripherals.
What debug interface does the UPD70F3767GF-GAT-M1-AX provide?
The UPD70F3767GF-GAT-M1-AX features IEEE 1149.1 JTAG interface with full boundary-scan capability and real-time trace output via SWO pin. It supports in-circuit debugging using Renesas E2 emulator or third-party tools compliant with V850ES debug specification. No external debug probe voltage translation is required, as the interface operates at the same voltage as the core supply (3.0–5.5 V).
Is the UPD70F3767GF-GAT-M1-AX qualified for automotive applications?
Yes, the UPD70F3767GF-GAT-M1-AX is qualified per AEC-Q100 Grade 2 (−40°C to +125°C), with built-in self-test features, memory ECC on SRAM, and failure-in-time (FIT) rate below 100 FIT. It meets automotive EMC standards including ISO 11452-2 (radiated immunity) and ISO 7637-2 (transient burst immunity), making it suitable for under-hood and cabin-mounted electronic control units.
How much user-accessible Flash memory does the UPD70F3767GF-GAT-M1-AX have?
UPD70F3767GF-GAT-M1-AX provides 512 KB of on-chip Flash memory, fully user-programmable and erasable in blocks or pages. After reserving space for bootloader (typically 8–16 KB) and security configuration, approximately 496 KB remains available for application code and data. Flash endurance is rated at 100,000 write/erase cycles with data retention exceeding 20 years at 85°C.
