FAQ
What is the maximum operating frequency and instruction throughput of the R5F10268GSP#55?
The R5F10268GSP#55 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. Its minimum instruction execution time is 0.04167 µs at 24 MHz, enabled by the RL78's 3-stage pipeline CISC architecture. The R5F10268GSP#55 maintains this performance across its full 1.8 V to 5.5 V supply range and –40°C to +105°C temperature grade.
Does the R5F10268GSP#55 support in-field firmware updates via its data flash memory?
Yes, the R5F10268GSP#55 includes 2 KB of dedicated data flash memory with background operation (BGO) capability, allowing the R5F10268GSP#55 to execute application code from program memory while simultaneously rewriting data flash. This enables safe, atomic firmware parameter updates and logging without interrupting real-time control functions.
What industrial temperature qualification does the R5F10268GSP#55 hold, and how is it reflected in the part number?
The R5F10268GSP#55 is qualified for –40°C to +105°C operation, indicated by the "G" in its ordering code (R5F10268GSP#55). This G-grade certification ensures guaranteed functionality and parametric performance across the full extended industrial temperature range - critical for deployment in motor drives, power supplies, and outdoor infrastructure.
How many analog input channels and what ADC resolution does the R5F10268GSP#55 provide?
The R5F10268GSP#55 integrates an 11-channel, 10-bit successive-approximation ADC with internal 1.45 V reference voltage and integrated temperature sensor. Input channels include ANI0–ANI3 and ANI16–ANI22, supporting both single-ended and differential measurements - sufficient for multi-sensor industrial monitoring without external signal conditioning.
Is the R5F10268GSP#55 pin-compatible with other RL78/G12 20-pin variants such as R5F10267GSP#55 or R5F10269GSP#55?
Yes, the R5F10268GSP#55 shares identical 20-pin LSSOP packaging, pinout, and peripheral mapping with all R5F102xxGSP#55 variants (including R5F10267GSP#55 and R5F10269GSP#55). This allows direct PCB reuse across memory-density variants - only code flash size (4 KB / 8 KB / 12 KB) and RAM (256 B / 512 B / 768 B) differ between these compatible parts.
