Product details
Overview
R5F11W67DSM#70 from Renesas Electronics is an ultra-low-power 16-bit RL78/G1M microcontroller with 4 KB flash memory, 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#70 datasheet, R5F11W67DSM#70 pinout, R5F11W67DSM#70 application, or R5F11W67DSM#70 equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, confirmed industrial use cases, and two rigorously cross-checked alternative parts - all grounded in Renesas' official R01DS0378EJ0100 Rev.1.00 documentation.
Technical Context
The R5F11W67DSM#70 implements the RL78-S1 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.05 µs (20 MHz) to 1.0 µs (1 MHz). Its power management includes HALT and STOP modes, with typical supply current of 2.19 mA (20 MHz, VDD = 5 V), 390 µA (HALT), and 0.61 µA (STOP at 3 V).
It features a high-accuracy ±2.0% on-chip oscillator (1.25–20 MHz selectable), 15 kHz low-speed oscillator (±15%), and supports peripheral I/O redirection via PIOR register. The device includes real-time output capability (8 channels), programmable clock/buzzer output (PCLBUZ0), and key interrupt support for up to 8 inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Flash / RAM | 4 KB code flash / 512 B RAM; sufficient for compact firmware with sensor data buffering |
| ADC | 8-channel 8/10-bit A/D converter (VDD = 2.4–5.5 V); supports direct analog sensing without external signal conditioning |
| Timers | Four 16-bit timer channels + 12-bit interval timer + watchdog; enables PWM generation, time-stamping, and system supervision |
| Oscillator | High-speed on-chip oscillator ±2.0% accuracy (20 MHz max); eliminates external crystal cost and board space |
| Supply Range | VDD = 2.25–5.5 V (per SPOR voltage constraints); compatible with wide-input industrial power rails |

Pinout & Package
Package: 20-pin plastic TSSOP (4.4 × 6.5 mm, 0.65 mm pitch), RoHS-compliant, industrial-grade reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | Main 2.25–5.5 V supply rail; decoupling required per Renesas layout guidelines |
| VSS | Ground | Digital ground reference; must be connected to low-impedance PCB plane |

FAQ
What is the maximum operating frequency and instruction execution time of the R5F11W67DSM#70?
The R5F11W67DSM#70 supports a maximum high-speed on-chip oscillator frequency of 20 MHz, delivering a minimum instruction execution time of 0.05 µs under those conditions (VDD ≥ 2.7 V). At lower supply voltages (2.0–2.7 V), the minimum execution time extends to 0.2 µs. This timing is fully specified in Renesas' R01DS0378EJ0100 Rev.1.00 AC Characteristics table.
Does the R5F11W67DSM#70 include an on-chip debug interface, and can it be used in production?
Yes, the R5F11W67DSM#70 includes an on-chip debug function for development and evaluation. However, Renesas explicitly prohibits its use in mass-produced products due to flash memory rewrite endurance limitations - repeated debug access may exceed guaranteed erase/write cycles and compromise reliability. Production units must disable or omit debug functionality per Renesas' caution in Section 2 of R01DS0378EJ0100.
What are the key differences between the R5F11W67DSM#70 and R5F11W68DSM#70?
The R5F11W67DSM#70 and R5F11W68DSM#70 share identical package, pinout, peripherals, and electrical characteristics - the sole difference is memory capacity: R5F11W67DSM#70 has 4 KB flash and 512 B RAM, while R5F11W68DSM#70 provides 8 KB flash and 1 KB RAM. Both are industrial-grade (D-suffix) and fully pin-compatible per Renesas' ordering part number documentation.
Can the R5F11W67DSM#70 drive 24 V industrial inputs directly?
No, the R5F11W67DSM#70 I/O pins operate at VDD (2.25–5.5 V) and are not rated for 24 V. However, its 14 N-ch open-drain outputs tolerate VDD-level voltage on the drain side, enabling safe interfacing with 24 V external circuits when used with appropriate pull-up resistors and external level-shifting or optocoupler isolation - as confirmed in Section 1.6 and Table 2.3.1 of R01DS0378EJ0100.
What oscillator accuracy does the R5F11W67DSM#70 guarantee over its full temperature and voltage range?
The R5F11W67DSM#70 guarantees ±2.0% accuracy for its high-speed on-chip oscillator across TA = –20°C to +85°C and VDD = 2.0–5.5 V, as specified in Section 2.2.1 of R01DS0378EJ0100. At colder temperatures (–40°C to –20°C), accuracy degrades to ±3.0%. This eliminates need for external crystals in non-precision timing applications like sensor polling or UART communication at moderate baud rates.
