Product details
Overview
R5F11W67DSM#10 from Renesas is an ultra-low-power 16-bit RL78/G1M microcontroller with 4 KB flash, 512 B RAM, and 20-pin TSSOP package. It integrates an 8-channel 8/10-bit ADC, UART/CSI serial interfaces, four 16-bit timers, watchdog and interval timers, and operates across –40°C to +85°C for industrial sensor and control applications.
For engineers reviewing the R5F11W67DSM#10 datasheet, R5F11W67DSM#10 pinout, R5F11W67DSM#10 application, or R5F11W67DSM#10 equivalent, this page delivers verified specifications, real-time output capability, SPOR reset voltage options, N-ch open-drain I/O configuration, and industrial-grade temperature compliance - all critical for embedded control design validation.
Technical Context
The R5F11W67DSM#10 implements the RL78-S1 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.05 µs (20 MHz) to 1.0 µs (1 MHz). Its peripheral set includes a 12-bit interval timer, programmable clock/buzzer output (PCLBUZ0), and key interrupt support across eight KR pins.
It features dual on-chip oscillators: a high-speed oscillator selectable from 1.25–20 MHz (±2% accuracy at –20°C to +85°C) and a 15 kHz low-speed oscillator (±15%). Power management includes HALT and STOP modes, with STOP-mode current as low as 0.61 µA at VDD = 3.0 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11W68DSM#10 | 8 KB flash / 1 KB RAM; identical pinout, peripherals, and package; higher memory for larger firmware or bootloader + app partitioning. | Required when firmware exceeds 4 KB or when dual-bank OTA updates are needed. | Select R5F11W68DSM#10 if future firmware growth or secure boot requirements demand extra memory headroom. |
| R5F11Y67DSM#10 | RL78/G1N variant; adds high-current P-ch open-drain outputs (–120 mA per pin) but removes RTIO functionality. | Suitable for LED driver or segment LCD bias applications where high sink current matters more than real-time pulse generation. | Choose R5F11Y67DSM#10 only when driving high-current displays or discrete loads outweighs need for RTIO or real-time output timing. |
Compared with R5F11W67DSM#10, R5F11W68DSM#10 offers scalable memory without layout changes, while R5F11Y67DSM#10 trades RTIO for higher drive strength - making the R5F11W67DSM#10 optimal for time-critical industrial control where deterministic pulse generation and low-power sensing coexist.

FAQ
What is the maximum operating frequency of the R5F11W67DSM#10?
The R5F11W67DSM#10 supports a maximum high-speed on-chip oscillator frequency of 20 MHz, enabling a minimum instruction execution time of 0.05 µs. This frequency is selectable via option byte settings and maintains ±2% accuracy across –20°C to +85°C, making it suitable for timing-critical industrial control loops without external crystal dependency.
Does the R5F11W67DSM#10 support real-time output functionality?
Yes, the R5F11W67DSM#10 includes 8-channel real-time output (RTIO) capability, exclusive to the RL78/G1M group. This feature allows hardware-synchronized pulse generation on designated pins (e.g., RTIO00–RTIO07) without CPU intervention - essential for motor commutation, LED dimming, or encoder signal generation in industrial systems.
What are the key differences between R5F11W67DSM#10 and R5F11Y67DSM#10?
The R5F11W67DSM#10 belongs to the RL78/G1M group and includes 8-channel RTIO and standard N-ch open-drain I/O. The R5F11Y67DSM#10 is an RL78/G1N variant with high-current P-ch open-drain outputs (–120 mA per pin) but no RTIO. Both share identical flash/RAM (4 KB/512 B), package, and industrial temperature rating.
Can the R5F11W67DSM#10 operate from a 2.0 V supply?
The R5F11W67DSM#10 specifies an absolute minimum supply voltage of 2.0 V, but Renesas recommends operation within 2.25–5.5 V due to the selectable power-on-reset (SPOR) circuit's 2.25 V detection threshold. Below 2.25 V, reliable reset behavior is not guaranteed - design margins should maintain VDD ≥2.25 V for industrial reliability.
How many analog input channels does the R5F11W67DSM#10 support?
The R5F11W67DSM#10 integrates an 8-channel, 8/10-bit resolution A/D converter with analog inputs ANI0 through ANI7. These channels are mapped to physical pins P07, P10–P16, and P137, supporting single-ended measurements across the full 2.4–5.5 V VDD range - eliminating need for external ADCs in basic sensor interfacing.
