Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LJDFB#V0 | No data flash memory (0 KB); identical core, peripherals, and package | Not suitable for field-upgradable firmware or nonvolatile parameter storage | Select when application requires only code storage and uses external EEPROM or FRAM |
| R5F100LJAFB#V0 | 128 KB flash, 4 KB data flash, 12 KB RAM; otherwise identical peripheral set and pinout | Lower memory capacity limits complex GUI or protocol stack integration | Choose for cost-sensitive designs where 256 KB flash is unnecessary and BOM reduction is critical |

FAQ
What is the maximum operating frequency and corresponding instruction timing for the R5F100LJDFB#V0?
The R5F100LJDFB#V0 operates up to 32 MHz using its high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.03125 μs. The RL78 core also supports ultra-low-speed operation at 32.768 kHz (e.g., for RTC), where instruction time extends to 30.5 μs - enabling precise trade-offs between performance and power in the R5F100LJDFB#V0.
Does the R5F100LJDFB#V0 support background data flash rewriting while executing code from main flash?
Yes, the R5F100LJDFB#V0 supports Background Operation (BGO) for data flash. This allows the CPU to execute instructions from program memory while simultaneously rewriting data flash - essential for seamless firmware updates or runtime parameter storage without interrupting real-time tasks in the R5F100LJDFB#V0.
How many analog input channels does the R5F100LJDFB#V0 provide, and what reference options are available?
The R5F100LJDFB#V0 features a 10-bit ADC with up to 26 analog input channels. It supports internal 1.45 V reference voltage and external reference inputs. The internal reference and integrated temperature sensor are usable only in HS (high-speed main) mode, as specified in the R5F100LJDFB#V0 datasheet.
What low-power modes are available on the R5F100LJDFB#V0, and which peripherals remain active in each?
The R5F100LJDFB#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode, only RTC and LVD remain active (0.57 μA). In SNOOZE mode, selected peripherals like UART or ADC can operate autonomously while CPU sleeps. HALT stops the CPU clock but retains RAM and register contents - all three modes are fully supported in the R5F100LJDFB#V0.
Is the R5F100LJDFB#V0 pin-compatible with other RL78/G13 variants in the same 64-pin LFQFP package?
Yes, all RL78/G13 devices in the 64-pin LFQFP package (e.g., R5F100LJAFB#V0, R5F101LJDFB#V0) share identical pinouts and electrical characteristics. This enables hardware reuse across memory variants - the R5F100LJDFB#V0 can be substituted without PCB changes, provided firmware accommodates flash/RAM size differences.
