FAQ

What is the maximum operating frequency of the UPD70F3762GC-UEU-AX?

The UPD70F3762GC-UEU-AX operates at a maximum CPU clock frequency of 40 MHz, achieved via its on-chip PLL configured with an external crystal or oscillator input ranging from 1 MHz to 40 MHz. This frequency is sustained across the full −40°C to +125°C operating temperature range, with timing margins verified per Renesas Hardware User's Manual Rev.5.10.

Does the UPD70F3762GC-UEU-AX include a built-in CAN controller?

Yes, the UPD70F3762GC-UEU-AX integrates a single CAN 2.0B-compliant controller supporting bit rates up to 1 Mbit/s, 32 message objects, and hardware-based acceptance filtering. It requires only an external CAN transceiver (e.g., TJA1050) for physical layer compliance - no additional logic or firmware abstraction layer is needed to implement standard CAN communication in UPD70F3762GC-UEU-AX designs.

What package type and pin count does the UPD70F3762GC-UEU-AX use?

The UPD70F3762GC-UEU-AX is supplied in a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments are documented in Chapter 1.5 "Pin Configuration (Top View)" of the V850ES/JG3-H Hardware User's Manual Rev.5.10, and include dedicated CAN, JTAG, ADC, and general-purpose I/O functions mapped across 10 port groups.

Is the UPD70F3762GC-UEU-AX qualified for automotive applications?

The UPD70F3762GC-UEU-AX is qualified per AEC-Q100 Grade 2 (−40°C to +105°C case temperature), making it suitable for automotive body electronics such as door modules and lighting controllers. While not rated for powertrain or safety-critical ASIL-B applications, its industrial temperature grade (−40°C to +125°C) and CAN integration align with automotive-adjacent industrial use cases where reliability under thermal stress is essential.

How much on-chip Flash and RAM does the UPD70F3762GC-UEU-AX provide?

The UPD70F3762GC-UEU-AX includes 512 KB of on-chip Flash memory with 100,000 write/erase cycle endurance and 48 KB of SRAM with parity-based error detection. Flash is organized in 128-byte pages for fine-grained updates, and SRAM supports both byte- and word-access modes - enabling efficient real-time data logging and control variable storage without external memory expansion in UPD70F3762GC-UEU-AX implementations.
