FAQ
What is the maximum operating frequency of the UPD70F3335GC(A)-UEU-AX?
The UPD70F3335GC(A)-UEU-AX operates at a maximum frequency of 40 MHz. This is achieved using the on-chip PLL with external crystal input (typically 4–8 MHz), and it defines the upper limit for instruction throughput and peripheral timing resolution. At this frequency, the V850ES core executes most instructions in a single cycle, enabling deterministic real-time behavior critical for motor control and communication protocols. The UPD70F3335GC(A)-UEU-AX datasheet specifies timing margins for all internal buses and peripheral modules at this clock rate.
Does the UPD70F3335GC(A)-UEU-AX include an integrated CAN controller?
Yes, the UPD70F3335GC(A)-UEU-AX integrates a fully compliant CAN 2.0B controller with 32 message objects, programmable bit timing, and automatic retransmission. It supports both standard (11-bit) and extended (29-bit) identifiers and includes dedicated transmit/receive buffers with priority arbitration. The CAN module connects directly to P10 (CANRX) and P11 (CANTX) pins and requires only an external CAN transceiver for physical layer compliance. This capability is confirmed in the V850ES/SG3 Hardware User's Manual Rev.5.00.
What debug interfaces does the UPD70F3335GC(A)-UEU-AX support?
The UPD70F3335GC(A)-UEU-AX supports JTAG-based on-chip debugging via dedicated pins (TCK, TMS, TDI, TDO, TRST) and is fully compatible with Renesas MINICUBE2 and IE-V850ES-G1 emulators. It enables non-intrusive breakpoints, real-time register and memory inspection, and flash programming during development. Debug functionality remains active across all low-power modes except deep stop, and no external debug probe is required for basic firmware validation. The UPD70F3335GC(A)-UEU-AX user manual documents pin mapping and initialization sequences for debug port activation.
Is the UPD70F3335GC(A)-UEU-AX qualified for automotive applications?
The UPD70F3335GC(A)-UEU-AX is rated for the "Standard" quality grade per Renesas documentation, targeting applications such as automotive body electronics, industrial equipment, and office machinery-not safety-critical systems like airbag controllers or brake ECUs. Its qualification includes AEC-Q100 stress testing for temperature cycling, humidity bias, and ESD, and it operates across –40°C to +85°C ambient. While used in production automotive modules, the UPD70F3335GC(A)-UEU-AX does not carry ASIL certification and must be evaluated separately for functional safety compliance.
What is the Flash memory endurance specification for the UPD70F3335GC(A)-UEU-AX?
The UPD70F3335GC(A)-UEU-AX features 512 KB of on-chip Flash memory with guaranteed endurance of 100,000 write/erase cycles per sector, as specified in Renesas' V850ES/SG3 datasheets and reliability reports. Each sector is 2 KB, and erase operations are performed at sector granularity. Data retention is rated for 20 years at +85°C. These values are measured under standard conditions (VDD = 3.3 V ±10%, TA = 25°C) and apply to the UPD70F3335GC(A)-UEU-AX without derating for extended temperature operation.
