Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LGAFA#30 | Same 64-pin LQFP package, 96 KB flash, 8 KB RAM, identical peripheral set | Lower memory footprint suits simpler control tasks with smaller firmware and reduced data buffering needs | Select when application firmware size remains under 96 KB and cost optimization is prioritized over future scalability |
| R5F100LHAFA#30 | Same 64-pin LQFP package, 128 KB flash, but includes 8 KB data flash (vs. none in R5F101LHAFA#30) | Required where frequent non-volatile parameter storage (e.g., calibration tables, usage logs) must survive power loss without external EEPROM | Choose when field-updatable configuration persistence is mandatory and additional 4 KB RAM is not needed |
Compared with R5F101LHAFA#30, R5F101LGAFA#30 reduces flash capacity by 32 KB but maintains identical low-power performance and I/O count for cost-sensitive volume production, while R5F100LHAFA#30 trades off the absence of data flash for guaranteed parameter retention - making it preferable in applications requiring robust field updates without external memory.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101LHAFA#30?
The R5F101LHAFA#30 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs in this mode, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time. This flexibility allows precise trade-offs between speed and energy consumption in real-time embedded applications.
Does the R5F101LHAFA#30 include data flash memory?
No, the R5F101LHAFA#30 does not include data flash memory. As indicated by the "101" prefix in its part number per Renesas documentation, this variant provides 128 KB of code flash and 12 KB of RAM but omits the dedicated data flash block. Applications requiring non-volatile parameter storage must use external EEPROM or leverage the code flash with wear-leveling software, unlike the "100" series (e.g., R5F100LHAFA#30) which includes 8 KB of data flash.
What package type and pin count does the R5F101LHAFA#30 use?
The R5F101LHAFA#30 uses a 64-pin LQFP package with 0.65-mm pitch (12 × 12 mm body), designated by the "FA" suffix in its part number. This package provides 48 general-purpose I/O pins, multiple power/ground pairs for noise immunity, and compatibility with standard PCB assembly processes. It is distinct from LFQFP (FB), HWQFN (NA), or VFBGA (BG) variants in the RL78/G13 family.
What are the supported low-power modes of the R5F101LHAFA#30 and their typical current draws?
The R5F101LHAFA#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.57 μA - ideal for long-duration sleep states. HALT mode draws 66 μA/MHz during active operation, and SNOOZE mode enables selective peripheral operation (e.g., UART receive) while the CPU remains halted. All modes retain RAM content and support fast wake-up via interrupts or reset.
Which communication interfaces are integrated into the R5F101LHAFA#30?
The R5F101LHAFA#30 integrates three I²C/Simplified I²C channels, two UART/LIN-capable serial interfaces (supporting LIN 2.2 physical layer timing), and two CSI (SPI-compatible) channels. These interfaces enable concurrent connectivity to sensors (I²C), automotive sub-nodes (LIN), displays or memory (SPI), and host processors or modems (UART), all without external level shifters due to 1.8/2.5/3.0 V interface tolerance.
