FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F10267ASM#15?
The R5F10267ASM#15 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. This benchmark reflects integer instruction throughput under standard EEMBC CoreMark methodology and is validated across the full 1.8–5.5 V supply range and –40°C to +85°C ambient temperature. The R5F10267ASM#15 achieves this performance while maintaining 63 μA/MHz active current consumption - a key differentiator versus competing 16-bit MCUs.
Does the R5F10267ASM#15 include on-chip data flash memory, and what are its endurance specifications?
Yes, the R5F10267ASM#15 integrates 2 KB of on-chip data flash memory with background operation (BGO) capability, allowing program execution from code flash while simultaneously rewriting data flash. Its endurance is rated at 1,000,000 write/erase cycles (typical) across the full 1.8–5.5 V VDD range. This feature enables reliable storage of calibration data, device configuration, and usage logs in the R5F10267ASM#15 without requiring external EEPROM or FRAM components.
What safety features are implemented in the R5F10267ASM#15, and how do they support functional safety compliance?
The R5F10267ASM#15 includes CRC calculation hardware, RAM guard, and SFR guard - all documented in the RL78/G12 User's Manual as safety mechanisms for detecting memory corruption and preventing unauthorized register access. These features support IEC 61508 SIL2 and ISO 26262 ASIL-B development by enabling runtime integrity checks and fault containment. The R5F10267ASM#15 does not require external watchdog supervision for basic safety monitoring due to its integrated window watchdog timer and voltage detector with 12-level reset thresholds.
How many analog input channels does the R5F10267ASM#15 support, and what ADC resolution options are available?
The R5F10267ASM#15 supports 11 analog input channels (ANI0–ANI3, ANI16–ANI22) with an 8/10-bit successive approximation ADC. Resolution is software-selectable per conversion, and the module includes an internal 1.45 V reference voltage plus dedicated AVREFP/AVREFM pins for external reference configurations. The ADC supports scan mode, group conversion, and hardware-triggered sampling - all fully operational within the R5F10267ASM#15's 1.8–5.5 V supply range and –40°C to +85°C temperature grade.
What package type and pin count does the R5F10267ASM#15 use, and are there compatible footprint alternatives?
The R5F10267ASM#15 uses a 20-pin TSSOP package (PTSP0020JI-A) with 4.4 × 6.5 mm dimensions and 0.65-mm pitch. It shares identical mechanical footprint and thermal characteristics with other RL78/G12 20-pin variants including R5F10266ASM#15, R5F10268ASM#15, and R5F10269ASM#15 - enabling drop-in replacement within the same family. No pin-compatible alternatives exist outside the RL78/G12 series due to unique peripheral mapping and I/O redirection architecture in the R5F10267ASM#15.
