Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit USB-capable microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566TEADFP | RX66T core (48 MHz), 512 KB Flash, USB 2.0 FS, but no 5V-tolerant I/O - requires level shifters for 5V peripherals | Targeted at motor control with FPU and hardware trigonometric accelerators; less suited for mixed-voltage legacy interfaces | Select when prioritizing computational throughput over I/O voltage flexibility |
| UPD70F3795GC-UEU-AX | Same V850ES/JG3-L family, identical pinout and USB/ADC/peripheral set, but 384 KB Flash and 48 KB RAM | Drop-in replacement where reduced code size or lower cost is acceptable; same PCB layout and firmware compatibility | Select when application firmware fits within 384 KB and cost optimization is critical |
Compared with UPD70F3796GC-UEU-AX, the R5F566TEADFP offers higher CPU performance but lacks 5V-tolerant I/O, increasing BOM complexity; the UPD70F3795GC-UEU-AX shares full pin and software compatibility but trades Flash/RAM capacity for cost savings in resource-constrained designs.

FAQ
What is the maximum operating frequency of the UPD70F3796GC-UEU-AX?
The UPD70F3796GC-UEU-AX operates at a maximum CPU clock frequency of 40 MHz. This is achieved using the on-chip PLL with an external crystal (e.g., 8 MHz) or external clock source. The 40 MHz timing enables real-time execution of USB full-speed protocols (12 Mbps) and deterministic response to peripheral interrupts, as confirmed in Chapter 6 and Section 33 of the Hardware User's Manual Rev.4.00.
Does the UPD70F3796GC-UEU-AX support USB host functionality?
No, the UPD70F3796GC-UEU-AX supports USB device mode only. Its integrated USB 2.0 full-speed controller and PHY are configured exclusively for peripheral operation, including enumeration as a USB device and handling of control, interrupt, bulk, and isochronous endpoints. Host-mode capability is not implemented in the V850ES/JG3-L silicon, as stated in the "On-chip USB controller" section of the User's Manual.
What is the Flash memory endurance specification for the UPD70F3796GC-UEU-AX?
The UPD70F3796GC-UEU-AX features 512 KB of on-chip SuperFlash® memory rated for 100,000 write/erase cycles and greater than 20 years of data retention at 85°C. This endurance rating is specified in Renesas' Flash memory reliability documentation and applies to standard erase/program operations under recommended voltage and temperature conditions.
Is the UPD70F3796GC-UEU-AX pin-compatible with other members of the V850ES/JG3-L family?
Yes, the UPD70F3796GC-UEU-AX is pin-compatible with UPD70F3794GC-UEU-AX and UPD70F3795GC-UEU-AX in the LQFP-144 package. All three share identical pin functions, electrical characteristics, and package dimensions, enabling hardware reuse across variants differentiated by Flash/RAM size and peripheral enablement - as documented in Section 1.5 (Pin Configuration) and Table 1.1 (Ordering Information).
What debug interfaces are supported by the UPD70F3796GC-UEU-AX?
The UPD70F3796GC-UEU-AX supports on-chip debugging via the JTAG interface using Renesas' QB-V850MINIL or QB-MINI2 emulators. Debug functionality includes breakpoint setting, register inspection, and real-time trace, all accessible through dedicated pins (TRST, TCK, TMS, TDI, TDO) defined in Chapter 2 of the Hardware User's Manual. SWD is not supported.
