Overview
R5F10267DSP#35 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller designed for cost-sensitive, battery-operated consumer and industrial control applications. It integrates 4 KB code flash, 2 KB data flash, 256 B RAM, 10-bit A/D converter (11 channels), UART, two CSI channels, two simplified I²C channels, four 16-bit timer channels, and operates from 1.8 V to 5.5 V with true low-power consumption (63 μA/MHz).
For engineers reviewing the R5F10267DSP#35 datasheet, R5F10267DSP#35 pinout, R5F10267DSP#35 application, or R5F10267DSP#35 equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, application-specific use cases, and two confirmed alternative parts - all grounded in Renesas' official R01DS0193EJ0250 Rev.2.50 documentation.
Technical Context
The R5F10267DSP#35 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting minimum instruction execution time of 0.04167 µs at 24 MHz using the high-accuracy ±1.0% on-chip oscillator. It features dedicated hardware blocks including CRC calculation, RAM guard, SFR guard, and background operation (BGO) for data flash rewriting while executing program code.
Its peripheral set is optimized for compact embedded systems: dual CSI interfaces support SPI-like communication with slave select flexibility; dual simplified I²C channels enable multi-drop sensor interfacing; and the 10-bit A/D converter includes internal reference (1.45 V) and temperature sensor - all accessible via 18 I/O pins including 2× 6-V-tolerant N-ch open-drain outputs.

FAQ
What is the maximum operating frequency and corresponding instruction speed of the R5F10267DSP#35?
The R5F10267DSP#35 supports a maximum system clock of 24 MHz using its high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.04167 µs. This timing enables deterministic real-time response for motor control, sensor sampling, and communication protocols - critical for applications like thermostats and industrial monitors where jitter must be minimized.
Does the R5F10267DSP#35 include hardware support for functional safety standards such as IEC 61508?
Yes, the R5F10267DSP#35 includes hardware safety features required for SIL2-capable designs: CRC calculation unit, RAM guard, and SFR guard. These features detect memory corruption and unauthorized register writes. When combined with Renesas' safety libraries and proper system-level design, the R5F10267DSP#35 supports development of IEC 61508-compliant industrial controllers and home appliance safety monitors.
How does the data flash memory in the R5F10267DSP#35 differ from standard code flash in terms of usage and endurance?
The R5F10267DSP#35 includes 2 KB of dedicated data flash memory rated for 1,000,000 write/erase cycles (typical), compared to 100,000 cycles for code flash. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for logging sensor data or storing calibration parameters without interrupting real-time tasks.
Can the R5F10267DSP#35 operate reliably from a single 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F10267DSP#35 is fully specified for 1.8 V operation across its entire temperature range (–40°C to +85°C). At 1.8 V, all core functions remain active: 10-bit ADC (with internal 1.45 V reference), UART, CSI, simplified I²C, timers, and low-power modes. This enables direct integration with energy-harvesting circuits and single-cell lithium batteries without voltage boosting.
