For engineers reviewing the R5F10267GSM#55 datasheet, R5F10267GSM#55 pinout, R5F10267GSM#55 application, or R5F10267GSM#55 equivalent, key selection criteria include its G-grade (−40°C to +105°C) operation, integrated 10-bit 11-channel ADC, dual CSI/I²C serial interfaces, on-chip CRC and RAM guard safety features, and TSSOP20 package compatibility with legacy RL78/G12 designs.
Technical Context
The R5F10267GSM#55 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction execution time (0.04167 μs @ 24 MHz). It integrates a high-speed on-chip oscillator (±1.0% accuracy from −20°C to +85°C; ±2.0% at +105°C) and supports HS/LS clock modes for dynamic power scaling.
Its peripheral set includes 4-channel 16-bit TAU timer with PWM outputs, 1-channel 12-bit interval timer, window watchdog, 2-channel DMA controller, and SAU0-based serial interfaces (CSI00/CSI01, IIC00/IIC01, UART0), all accessible via dedicated pins or PIOR-redirected functions in the 20-pin TSSOP package.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F10267GSM#55?
The R5F10267GSM#55 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS of processing performance. This rating is measured under standard conditions (VDD = 2.7–5.5 V, TA = −40°C to +85°C) and reflects integer computational throughput per the EEMBC CoreMark methodology. The R5F10267GSM#55 maintains full peripheral functionality-including ADC, timers, and serial interfaces-at this speed.
Does the R5F10267GSM#55 support hardware CRC calculation, and how is it implemented?
Yes, the R5F10267GSM#55 includes a dedicated on-chip CRC calculation unit compliant with CRC-16-CCITT and CRC-32 standards. It operates independently of the CPU core, accepting data via memory-mapped registers or DMA transfers, and is explicitly documented in the RL78/G12 User's Manual Chapter 27. This hardware accelerator enables real-time frame integrity checking in communication stacks without CPU overhead-critical for R5F10267GSM#55-based industrial protocols.
What are the key differences between the R5F10267GSM#55 and the R5F10367GSM#55?
The R5F10267GSM#55 includes 2 KB of data flash memory, on-chip CRC, RAM guard, and SFR guard-features absent in the R5F10367GSM#55. Additionally, the R5F10267GSM#55 supports two CSI and two simplified I²C channels, whereas the R5F10367GSM#55 provides only one CSI and no simplified I²C. Both share identical code flash (4 KB), RAM (256 B), pinout, and G-grade temperature rating-but the R5F10267GSM#55 targets higher-integrity applications requiring nonvolatile parameter storage and functional safety.
Can the R5F10267GSM#55 operate reliably at +105°C, and what specifications are validated at that temperature?
Yes, the R5F10267GSM#55 is qualified for industrial G-grade operation from −40°C to +105°C. At +105°C, its high-speed on-chip oscillator accuracy is specified at ±2.0%, voltage detector thresholds remain stable across 12 selectable levels, and all digital peripherals-including timers, UART, and ADC-retain full functionality. Electrical characteristics such as I/O drive strength and flash programming endurance are validated per Renesas' R01DS0193EJ0250 datasheet Section 2.1 and 2.2 for the full G-grade range.
How does the R5F10267GSM#55 handle analog reference voltage for its 10-bit ADC?
The R5F10267GSM#55 provides dedicated AVREFP (P20) and AVREFM (P21) pins for external analog reference inputs, and includes an internal 1.45 V reference voltage source usable for ratiometric measurements. The ADC supports single-ended and differential input modes, with programmable sampling time and conversion triggers from timers or software. This dual-reference capability ensures accurate sensor readings across varying supply voltages-essential for R5F10267GSM#55 deployments in unregulated industrial power environments.
