Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100JGAFA#30 | Same 52-pin LQFP package, 192 KB flash, 8 KB data flash, 16 KB RAM - lower code density but identical peripheral set and power profile | Preferred where firmware footprint <192 KB reduces cost without sacrificing ADC count, timers, or LIN support | Select when application firmware fits within 192 KB and BOM cost optimization is prioritized over future scalability |
| R5F101JHAFA#30 | No data flash (0 KB); otherwise identical pinout, package, clock, and peripheral configuration - requires external EEPROM or FRAM for nonvolatile parameter storage | Suitable for fixed-function devices where calibration data is factory-programmed or stored externally | Choose when data retention requirements are met by external memory and eliminating data flash reduces unit cost and simplifies qualification |
Compared with R5F100JHAFA#30, R5F100JGAFA#30 trades 64 KB flash for lower unit cost while preserving all timing-critical peripherals, whereas R5F101JHAFA#30 removes data flash entirely - shifting nonvolatile storage responsibility to external components and reducing die size.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100JHAFA#30?
The R5F100JHAFA#30 operates up to 32 MHz using its high-speed on-chip oscillator. At this frequency, typical active current is 66 μA per MHz - resulting in ~2.1 mA total at 32 MHz under standard conditions (VDD = 3.3 V, TA = 25°C). In STOP mode with only RTC and LVD enabled, it draws just 0.57 μA, enabling multi-year battery life in intermittent-sensing applications.
Does the R5F100JHAFA#30 support in-system programming and secure firmware updates?
Yes, the R5F100JHAFA#30 supports full in-system programming via its on-chip debug interface. It includes boot swap functionality and flash shield window protection to prevent unauthorized access to code during updates. Self-programming allows firmware patches to be applied in the field without external programmers, and the flash library reserves RAM at address FAF00H for safe rewrite operations.
How many UART channels with LIN capability does the R5F100JHAFA#30 provide?
The R5F100JHAFA#30 provides four UART channels, all supporting LIN 2.2A protocol features including automatic sync-break detection, checksum calculation, and slave node response timing. Two of these (UART0 and UART1) are designated for LIN master/slave operation in the RL78/G13 datasheet and can drive standard LIN transceivers directly.
What is the ADC resolution, channel count, and reference voltage options on the R5F100JHAFA#30?
The R5F100JHAFA#30 integrates a 10-bit successive-approximation ADC with 26 input channels. It supports external VREF or internal 1.45 V reference (selectable via SFR), and includes an on-chip temperature sensor usable as a calibrated measurement source. The ADC operates across the full 1.6–5.5 V VDD range with typical INL of ±1 LSB.
Is the R5F100JHAFA#30 pin-compatible with other RL78/G13 variants in the same 52-pin LQFP package?
Yes, all RL78/G13 devices in the 52-pin LQFP-0.65mm package - including R5F100JCAFA#30 through R5F100JLAFA#30 and R5F101Jx series - share identical pinouts, electrical characteristics, and mechanical dimensions. This enables direct substitution across flash/RAM/data flash variants without PCB redesign, provided software accommodates memory map differences.
