FAQ

What is the maximum operating frequency of the UPD70F3913GC(R)-UEU-AX?

The UPD70F3913GC(R)-UEU-AX supports a maximum CPU clock frequency of 64 MHz when using the on-chip PLL with an external crystal or clock source. This frequency is achievable across the full industrial temperature range (−40°C to +85°C) and supply voltage range (2.7 V to 5.5 V), as verified in Renesas' Electrical Specifications chapter. The UPD70F3913GC(R)-UEU-AX maintains instruction timing integrity at this rate due to its 5-stage pipeline and zero-wait-state Flash access architecture.

Does the UPD70F3913GC(R)-UEU-AX include a CAN controller?

Yes, the UPD70F3913GC(R)-UEU-AX integrates a fully compliant CAN 2.0B controller with 32 message objects, programmable acceptance filtering, and dedicated transmit/receive buffers. It supports standard and extended frame formats and operates up to 1 Mbps. This CAN interface is implemented in hardware and requires no software bit-banging, making it suitable for real-time industrial networks. The UPD70F3913GC(R)-UEU-AX uses dedicated CANTX/CANRX pins routed to external transceivers per ISO 11898-2.

What development tools are supported for the UPD70F3913GC(R)-UEU-AX?

The UPD70F3913GC(R)-UEU-AX is supported by Renesas' QB-MINI2 on-chip debug emulator and MINICUBE2 debugger, both providing full JTAG-based flash programming and real-time trace. Software toolchain support includes CA850 C compiler (Ver. 3.20), ID850QB integrated debugger, and RX850 real-time OS. These tools are validated for UPD70F3913GC(R)-UEU-AX silicon revision and referenced in the V850E/IG4-H Hardware User's Manual Rev.3.00.

Is the UPD70F3913GC(R)-UEU-AX pin-compatible with other V850E/IG4-H devices?

Yes, the UPD70F3913GC(R)-UEU-AX shares the same 80-pin LQFP package and pinout as other V850E/IG4-H family members including μPD70F3919, μPD70F3920, and μPD70F3921. All share identical power, reset, clock, and peripheral pin assignments. This allows board-level reuse across variants - for example, UPD70F3913GC(R)-UEU-AX can replace μPD70F3920GC-UEU-AX without PCB changes, differing only in Flash size (512 KB vs. 768 KB) and part marking.

What is the Flash endurance specification for the UPD70F3913GC(R)-UEU-AX?

The UPD70F3913GC(R)-UEU-AX specifies 100,000 write/erase cycles for its on-chip Flash memory, as documented in Chapter 28 (Electrical Specifications) of the V850E/IG4-H Hardware User's Manual. This endurance applies under standard industrial conditions (25°C, VDD = 3.3 V) and is guaranteed across the full operating temperature range. The UPD70F3913GC(R)-UEU-AX also supports sector-erase and byte-programming operations, enabling robust firmware update and data logging implementations.
