FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F1026AGSM#35?
The R5F1026AGSM#35 features a high-speed on-chip oscillator rated for 1–24 MHz operation with ±1.0% accuracy over −20°C to +85°C and ±2.0% over −40°C to +105°C. This enables precise timing without external crystals in many applications, reducing BOM cost and board space. The oscillator supports dynamic switching between frequencies during runtime.
Does R5F1026AGSM#35 support background data flash rewriting while executing application code?
Yes, the R5F1026AGSM#35 supports background operation (BGO) for its 2 KB data flash memory. This allows the CPU to execute instructions from program memory while simultaneously erasing or programming data flash sectors - essential for seamless firmware updates and real-time parameter storage without interrupting control loops.
How many analog input channels does R5F1026AGSM#35 provide, and what is their resolution?
The R5F1026AGSM#35 integrates an 8/10-bit resolution A/D converter with 11 analog input channels (ANI0–ANI3, ANI16–ANI22). It includes an internal 1.45 V reference voltage and an integrated temperature sensor, enabling accurate sensor measurements across its full 1.8–5.5 V supply range without external references.
What safety features are included in R5F1026AGSM#35 that distinguish it from R5F103-series MCUs?
The R5F1026AGSM#35 includes CRC calculation, RAM guard, and SFR guard - safety features absent in R5F103-series parts. These enable runtime memory integrity checking, preventing silent data corruption in industrial and automotive applications where functional safety compliance (e.g., IEC 61508) is required.
Is R5F1026AGSM#35 pin-compatible with other RL78/G12 20-pin variants like R5F1026AASM#35?
Yes, the R5F1026AGSM#35 shares identical TSSOP-20 pinout and electrical characteristics with all R5F1026x-series 20-pin variants, including R5F1026AASM#35 and R5F10268GSM#35. This allows drop-in replacement across temperature grades and memory configurations without PCB redesign.
