Technical Context

The R5F10267GSM#35 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and selectable high-speed on-chip oscillator (1–24 MHz, ±1.0% accuracy at –20°C to +85°C). Its HALT/STOP/SNOOZE low-power modes enable sub-μA retention in battery-powered systems.

It features integrated safety functions including CRC operation, RAM guard, and SFR guard - exclusive to R5F102-series devices - alongside background data flash rewriting (BGO), self-programming capability, and on-chip debug support. All peripherals are accessible via 18 I/O pins in TSSOP20 package with 2 N-ch open-drain (6 V tolerant) and 4 N-ch open-drain (VDD-tolerant) outputs.

FAQ

What is the maximum operating frequency and instruction throughput of the R5F10267GSM#35?

The R5F10267GSM#35 achieves a maximum system clock of 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, confirmed in Renesas' R01DS0193EJ0250 Rev.2.50 datasheet Section 1.1. This throughput supports real-time control loops in motor drives and sensor fusion applications without external acceleration.

Does the R5F10267GSM#35 support in-system programming and data retention during power loss?

Yes, the R5F10267GSM#35 supports self-programming of code flash and background operation (BGO) for data flash writes - enabling firmware updates and parameter storage without halting application execution. Its 2 KB data flash guarantees 1,000,000 rewrite cycles at 1.8–5.5 V, and on-chip voltage detector (LVD) triggers interrupt/reset below user-selected thresholds to safeguard data integrity during brownout events.

How many analog input channels does the R5F10267GSM#35 provide, and what ADC resolution options are available?

The R5F10267GSM#35 integrates an 8/10-bit successive approximation ADC with 11 input channels (ANI0–ANI3, ANI16–ANI22), as specified in Section 1.1 and Table 1-1 of R01DS0193EJ0250 Rev.2.50. It includes internal 1.45 V reference and on-die temperature sensor, supporting ratiometric measurements and thermal compensation without external components.

What safety and reliability features are built into the R5F10267GSM#35 for industrial applications?

The R5F10267GSM#35 includes hardware CRC calculation, RAM guard, and SFR guard - features exclusive to the R5F102 series per Section 1.3.3 of R01DS0193EJ0250 Rev.2.50. These protect against memory corruption and unauthorized register access, supporting functional safety requirements in IEC 61508-compliant systems without software overhead.

Is the R5F10267GSM#35 pin-compatible with other RL78/G12 variants in the same package?

Yes, the R5F10267GSM#35 shares identical 20-pin TSSOP (PTSP0020JI-A) pinout with all R5F102xxGSM#35 and R5F102xxASM#35 variants, including R5F10268GSM#35 and R5F10269GSM#35. Pin functions are consistent across the family, allowing direct substitution where memory or temperature grade differences are acceptable per design requirements.
