FAQ

What is the maximum operating frequency of the UPD70F3089YGJ-UEN-AX?

The UPD70F3089YGJ-UEN-AX operates at a maximum frequency of 33 MHz when driven by its main clock oscillator (1–20 MHz crystal). This frequency enables sub-microsecond interrupt latency and supports real-time CAN message processing at 1 Mbps nominal bit rate. The V850/SC3 core achieves one instruction per cycle for most operations, making the UPD70F3089YGJ-UEN-AX suitable for time-critical control tasks in automotive and industrial environments.

Does the UPD70F3089YGJ-UEN-AX include on-chip Flash memory, and how is it programmed?

Yes, the UPD70F3089YGJ-UEN-AX integrates 512 KB of on-chip Flash memory. Programming is performed in-system using the FA-144GJ-UEN flash programming adapter, as documented in Chapter 17 of User's Manual U15109EJ3V0UD. The device supports sector erase, byte/word write, and verification without requiring external high-voltage programming signals - enabling field firmware updates and production-line programming without socketing.

What CAN protocol versions does the UPD70F3089YGJ-UEN-AX support?

The UPD70F3089YGJ-UEN-AX implements a fully compliant FCAN controller conforming to ISO 11898-1 (CAN 2.0B Active) for classical CAN frames only. It does not support CAN FD or higher-layer protocols like CANopen or DeviceNet natively - those require software stack implementation. The FCAN module provides 32 message buffers, programmable bit timing, automatic retransmission, and bus-off recovery, meeting requirements for ASAM MCD-2 MC and AUTOSAR Classic-compliant applications.

What is the ADC resolution and channel count of the UPD70F3089YGJ-UEN-AX?

The UPD70F3089YGJ-UEN-AX features a 10-bit successive-approximation ADC with 16 analog input channels. Conversion time is 1.2 µs per sample at maximum clock rate, and the ADC supports scan mode for sequential conversion across multiple channels. Input voltage range is 0 V to AVDD, with AVDD separately powered to minimize noise coupling - making the UPD70F3089YGJ-UEN-AX suitable for precision sensor interfacing in motor control and environmental monitoring applications.

Is the UPD70F3089YGJ-UEN-AX qualified for automotive applications?

The UPD70F3089YGJ-UEN-AX is classified as a "Standard" quality grade device per Renesas documentation, intended for computers, office equipment, communications gear, and industrial robots - not for automotive safety-critical systems. While it includes FCAN and operates across extended temperature ranges, it lacks AEC-Q100 qualification and functional safety certification (e.g., ISO 26262 ASIL-B). For automotive use, Renesas recommends qualified derivatives such as the R7F701024 or RH850/F1L series instead of the UPD70F3089YGJ-UEN-AX.
