Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F64112NLG | 512 KB flash + 8 KB × 2 data flash + 63 KB RAM - same 100-pin LGA package and N-temp grade | Supports larger firmware images and more extensive data logging; identical peripheral set and pinout | Select when firmware size exceeds 256 KB or extended RAM is required for buffering or encryption contexts |
| R5F64111DFB | 384 KB flash + 8 KB × 2 data flash + 63 KB RAM in 100-pin LQFP (PLQP0100KB-A); D-temp grade (–40°C to +85°C) | Same core/peripherals but different package (LQFP vs LGA) and wider temperature range - no pinout compatibility | Choose for through-hole assembly or extended environmental operation where LGA rework is impractical |
Compared with R5F6411FNLG#U0, R5F64112NLG offers higher memory capacity in identical form factor for feature-rich firmware, while R5F64111DFB trades LGA for LQFP and extends temperature range - both require PCB layout changes but preserve software compatibility.

FAQ
What is the operating voltage range for the R5F6411FNLG#U0?
The R5F6411FNLG#U0 operates from VCC1 = 3.0 V to 5.5 V and VCC2 = 3.0 V to VCC1. AVCC must be tied to VCC1, and analog inputs are referenced to AVCC/AVSS. This dual-supply design isolates noise-sensitive analog circuitry from digital switching transients, ensuring stable 10-bit ADC performance across the full voltage range.
Does the R5F6411FNLG#U0 support in-system programming?
Yes, the R5F6411FNLG#U0 supports on-chip debug and on-board flash programming via the NSD debug port. Using Renesas' E1/E20 emulators or compatible tools, firmware can be updated in-circuit without removing the R5F6411FNLG#U0 from the target board - enabling field upgrades and manufacturing calibration.
How many UART channels does the R5F6411FNLG#U0 provide, and which support I²C-bus?
The R5F6411FNLG#U0 provides nine UART channels (UART0–UART8). UART0 through UART6 support I²C-bus functionality in addition to standard asynchronous/synchronous serial operation. This allows shared pin usage for multiple protocols - for example, UART2 can serve as an I²C master for sensor networks while UART5 handles debug output.
What is the purpose of the VDC0 and VDC1 pins on the R5F6411FNLG#U0?
VDC0 and VDC1 are dedicated pins for decoupling the internal voltage regulator. A 100 nF ceramic capacitor must be placed directly between VDC0 and VDC1 to stabilize the internal core voltage. Failure to connect this capacitor results in unstable operation or failure to exit reset - it is not optional and cannot be substituted with bulk VCC1 decoupling.
Is the R5F6411FNLG#U0 pin-compatible with other R32C/111 Group devices?
Yes, all 100-pin R32C/111 Group devices - including R5F64110DFB, R5F64111NLG, and R5F64112NLG - share identical pin assignments and electrical characteristics in the PTLG0100KA-A (LGA) and PLQP0100KB-A (LQFP) packages. Memory and peripheral differences do not affect pin function mapping, enabling drop-in replacement for capacity or temp-range upgrades.
