Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104GLANA#20 | Same 48-pin HWQFN package, but 384 KB flash reduced to 256 KB; identical RAM (24 KB) and data flash (8 KB) | Lower code density limits complex protocol stacks (e.g., full TCP/IP or multi-sensor fusion); suitable for simpler control-only firmware | Select when application firmware fits within 256 KB and cost optimization is prioritized over future feature expansion |
| R5F104LKAFB#30 | 64-pin LFQFP package, 512 KB flash, 48 KB RAM, same G-grade temp rating; adds 4 more I/O pins and 2 extra ADC channels | Enables larger HMI interfaces, additional sensor inputs, or dual-bus communication (e.g., CAN + USB); requires PCB redesign | Choose for scalability path requiring >384 KB code space or >48 I/Os, accepting larger footprint and higher pin count |
Compared with R5F104GLANA#20, the R5F104GKANA#20 provides 128 KB more flash for enhanced firmware resilience and field-upgrade headroom; versus R5F104LKAFB#30, it offers identical G-grade reliability in a smaller 48-pin HWQFN package, reducing board area and assembly cost where I/O count permits.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104GKANA#20?
The R5F104GKANA#20 operates at up to 32 MHz with an RL78 CPU core delivering 44 DMIPS. Its high-speed on-chip oscillator supports selectable frequencies from 1 MHz to 64 MHz, with ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C. At 32 MHz, minimum instruction execution time is 0.03125 µs, enabling responsive real-time control in applications like motor commutation and sensor fusion.
Does the R5F104GKANA#20 support in-system programming and secure firmware updates?
Yes, the R5F104GKANA#20 supports self-programming of both code and data flash memory using the on-chip debug interface. It includes boot swapping, flash shield window protection, and block erase prohibition to prevent unauthorized modification. The 8 KB data flash supports background operation (BGO), allowing firmware parameters to be updated while application code continues executing - essential for secure over-the-air (OTA) updates in field-deployed devices.
What analog peripherals are integrated into the R5F104GKANA#20 and how are they configured?
The R5F104GKANA#20 integrates a 10-bit ADC with 20 input channels, dual 8-bit DACs, two comparators, and an on-die temperature sensor. The ADC supports internal 1.45 V reference and simultaneous sampling with hardware triggers from timers or ELC events. DAC outputs are rail-to-rail (0–VDD) with real-time update capability. All analog blocks share common AVREFP/AVREFM pins and are accessible via P20–P27 analog I/O bank, configurable through dedicated control registers.
How does the Event Link Controller (ELC) enhance real-time performance in the R5F104GKANA#20?
The ELC in the R5F104GKANA#20 enables direct hardware-level linking of up to 26 peripheral events (e.g., ADC end-of-conversion, timer overflow, UART receive complete) to target functions (e.g., start ADC conversion, trigger DMA, increment counter) without CPU involvement. This eliminates interrupt latency and CPU overhead, ensuring deterministic response times critical for motor control loops, synchronized sensor acquisition, and time-triggered communication protocols.
What packaging and thermal specifications apply to the R5F104GKANA#20?
The R5F104GKANA#20 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed die pad recommended to be connected to VSS for thermal dissipation. It is rated for industrial operation from -40°C to +105°C (G-grade), validated per JEDEC JESD22-A104. The device achieves 0.60 μA typical current in STOP mode with RTC and LVD active, making it suitable for thermally constrained environments such as sealed industrial enclosures and portable medical housings.
