FAQ
What is the maximum operating frequency and corresponding DMIPS performance of the R5F10268GSM#15?
The R5F10268GSM#15 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS of processing performance. This is measured under HS (high-speed main) mode with VDD ≥ 2.7 V. The minimum instruction execution time is 0.04167 µs at 24 MHz, enabling deterministic real-time response in motor control and sensor fusion applications.
Does the R5F10268GSM#15 support background data flash rewriting (BGO)?
Yes, the R5F10268GSM#15 supports background data flash rewriting (BGO), allowing the CPU to execute instructions from program memory while simultaneously rewriting the 2 KB data flash. This feature is essential for firmware-over-the-air (FOTA) updates and runtime parameter logging without interrupting system operation - a capability confirmed in the RL78/G12 datasheet section 1.1 Features.
What are the key differences between the R5F10268GSM#15 and the R5F10368GSM#15?
The R5F10268GSM#15 includes 2 KB data flash, DMA controller (2 channels), CRC engine, RAM guard, SFR guard, and ±1.0% oscillator accuracy - features absent in the R5F10368GSM#15. The latter lacks data flash, DMA, and safety peripherals, and has ±5.0% oscillator tolerance. These differences make R5F10268GSM#15 suitable for industrial applications requiring field updates and functional safety, while R5F10368GSM#15 targets cost-sensitive consumer designs.
Which package type and pin count does the R5F10268GSM#15 use?
The R5F10268GSM#15 uses a 20-pin TSSOP package (PTSP0020JI-A) with 4.4 × 6.5 mm dimensions and 0.65-mm pitch. This package is explicitly designated by the "SM" suffix in the part number and confirmed in Table 1-1 of the RL78/G12 datasheet (page 4), where R5F10268GSM#15 is listed under "20-pin plastic TSSOP" with packaging specification #15 (tray).
What analog capabilities does the R5F10268GSM#15 provide for sensor interfacing?
The R5F10268GSM#15 integrates a 10-bit resolution A/D converter with 11 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. It supports single-ended and differential measurements across ANI0–ANI3 and ANI16–ANI22, enabling direct connection to thermistors, current-sense amplifiers, and environmental sensors without external references or signal conditioning.
