It integrates 2 KB code flash, 2 KB data flash, 256 B RAM, 10-bit 11-channel ADC, and operates from 1.8 V to 5.5 V with 63 μA/MHz active current. It delivers 31 DMIPS at 24 MHz and supports HALT/STOP/SNOOZE low-power modes for battery-powered sensor nodes and smart actuators.
For engineers reviewing the R5F10267GSP#V5 datasheet, R5F10267GSP#V5 pinout, R5F10267GSP#V5 application, or R5F10267GSP#V5 equivalent, key selection criteria include its G-grade industrial temp rating, on-chip 2 KB data flash with 1M rewrite cycles, dual CSI/I²C serial interfaces, 2-channel DMA, and CRC hardware - all in a compact 4.4 × 6.5 mm LSSOP-20 package with tube packaging (#V5).
Technical Context
The R5F10267GSP#V5 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.04167 µs min @ 24 MHz). Its clock system combines a high-accuracy ±1.0% (–20 to +85°C) high-speed on-chip oscillator (1–24 MHz selectable) with external crystal support (1–20 MHz) and a 15 kHz low-speed on-chip oscillator.
Peripheral integration includes TAU0 16-bit timer (4 channels), window watchdog timer, 12-bit interval timer, on-chip voltage detector (12-level LVD), power-on reset, and safety features exclusive to R5F102 series: CRC operation, RAM guard, and SFR guard - confirming its targeting of functional-safety-aware industrial firmware.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10267ASP#V5 | A-grade (–40°C to +85°C); identical memory, peripherals, and pinout; lacks G-grade extended temperature qualification. | Suitable for consumer-grade appliances and non-enclosed indoor equipment where ambient stays below +85°C. | Select when cost sensitivity outweighs extended temperature requirement and industrial certification is not mandated. |
| R5F10367GSP#V5 | No data flash (0 KB); no DMA; no CRC/RAM/SFR guards; ±5.0% oscillator accuracy; reduced serial interface count (1 CSI, 0 simplified I²C). | Targeted at cost-optimized, lower-reliability applications such as basic remote controls or disposable instrumentation. | Choose only if data logging, functional safety features, or high-precision timing are unnecessary - not a drop-in replacement. |
Compared with R5F10267GSP#V5, the A-grade R5F10267ASP#V5 offers identical functionality at lower cost but sacrifices +105°C operation and industrial qualification, while R5F10367GSP#V5 removes critical reliability features (data flash, CRC, guards) and reduces peripheral capability - making it unsuitable for safety-critical or field-upgradable designs.

FAQ
What is the maximum operating frequency and associated performance of the R5F10267GSP#V5?
The R5F10267GSP#V5 achieves a maximum system clock of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS of processing performance. Its minimum instruction execution time is 0.04167 µs under this condition. The device also supports external crystal oscillation up to 20 MHz and low-speed on-chip operation at 15 kHz for ultra-low-power sleep states - all verified across its –40°C to +105°C operating range.
Does the R5F10267GSP#V5 support in-system programming and data retention during power loss?
Yes, the R5F10267GSP#V5 supports self-programming of its 2 KB code flash and 2 KB data flash memory via on-chip debug or user firmware. The data flash guarantees 1,000,000 rewrite cycles and operates down to VDD = 1.8 V, enabling reliable parameter storage and firmware updates even during brown-out conditions - critical for industrial black-box logging and FOTA deployment.
How many analog input channels does the R5F10267GSP#V5 provide, and what reference options are available?
The R5F10267GSP#V5 integrates an 11-channel 10-bit A/D converter with inputs ANI0–ANI3 and ANI16–ANI22. It supports three reference configurations: external differential (AVREFP/AVREFM), internal 1.45 V bandgap reference, and VDD-referenced conversion - allowing flexible sensor interfacing from precision thermistors to ratiometric bridge circuits without external reference ICs.
What safety-related hardware features are included in the R5F10267GSP#V5?
The R5F10267GSP#V5 includes CRC calculation hardware, RAM guard, and SFR guard - features exclusive to the R5F102 product family. These enable runtime memory integrity checking, prevention of accidental register corruption, and detection of data path errors, forming foundational elements for achieving IEC 61508 SIL-2 or ISO 13849 PLd compliance in industrial control firmware.
Can the R5F10267GSP#V5 operate from a single 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F10267GSP#V5 is fully specified for operation from 1.8 V to 5.5 V. At 1.8 V, all core functions remain active: 2 KB code/data flash, 256 B RAM, 10-bit ADC (with internal 1.45 V reference), UART, CSI, simplified I²C, TAU0 timers, and low-power modes (HALT/STOP/SNOOZE). This enables direct integration with energy-harvesting PMUs and single-cell LiFePO₄ battery systems.
