Product details
Overview
R5F11W67DSM#30 from Renesas is an ultra-low-power 16-bit RL78/G1M microcontroller in 20-pin TSSOP package, featuring 4 KB flash, 512 B RAM, 8-channel 8/10-bit ADC, 4-channel 16-bit timer, UART/CSI serial interfaces, and real-time output capability - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F11W67DSM#30 datasheet, R5F11W67DSM#30 pinout, R5F11W67DSM#30 application, or R5F11W67DSM#30 equivalent, key selection criteria include industrial-grade temperature range (−40°C to +85°C), TSSOP-20 package compatibility, 4 KB flash with on-chip debug, ultra-low HALT/STOP mode current (≤980 µA / ≤2.35 µA), and real-time output support for timing-critical actuation.
Technical Context
The R5F11W67DSM#30 implements the RL78-S1 CPU core with 3-stage pipeline, supporting instruction execution times from 0.05 µs (20 MHz) to 0.8 µs (1 MHz). It integrates a selectable power-on-reset (SPOR) circuit with four detection thresholds (2.25 V to 4.45 V) and dual on-chip oscillators: high-speed (1.25–20 MHz, ±2% accuracy) and low-speed (15 kHz, ±15%).
Its peripheral set includes one UART channel, one CSI channel, eight analog inputs routed to a single 8/10-bit A/D converter, and four independent 16-bit timer channels capable of PWM output and input capture. Real-time output functionality (8 channels) is exclusive to the RL78/G1M group and enabled via dedicated RTIO pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78-S1 16-bit CISC with 3-stage pipeline; enables deterministic real-time response in resource-constrained embedded systems. |
| Flash / RAM | 4 KB code flash memory and 512 B on-chip RAM; sufficient for compact firmware with sensor interface logic and basic control algorithms. |
| Operating Voltage | 2.0–5.5 V supply (use 2.25–5.5 V recommended); supports direct connection to common industrial rails including 3.3 V and 5 V without level-shifting. |
| Temperature Range | −40°C to +85°C ambient operating range; qualified for industrial automation, building controls, and factory instrumentation. |
| Low-Power Modes | HALT mode (≤980 µA @ 3–5 V) and STOP mode (≤2.35 µA @ 3 V); enables multi-year battery life in wireless sensor endpoints. |
| A/D Converter | 8-channel 8/10-bit ADC (VDD = 2.4–5.5 V); supports simultaneous sampling of analog sensors such as thermistors, potentiometers, and current shunts. |

Pinout & Package
Package: 20-pin plastic TSSOP (4.4 × 6.5 mm, 0.65 mm pitch), lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | Main positive supply rail (2.0–5.5 V); decoupling capacitor required adjacent to pin for stable operation. |
| VSS | Ground | Digital ground reference; must be connected to system GND plane with low-impedance path. |
| P00–P05 | CMOS I/O (N-ch open-drain) | 14 N-ch open-drain outputs with VDD-tolerant capability; usable for driving LEDs, relays, or interfacing with 5 V logic. |
| P06, P07, P10–P16, P40 | CMOS I/O (N-ch open-drain) | Additional N-ch open-drain outputs; P06/P10 do not output high level in N-ch mode per datasheet caution. |
| P125 | RESET / KR1 | Active-low reset input with internal pull-up; also serves as key return line for matrix keypad scanning. |
| P137 | INTP0 / TI00 | External interrupt input or timer input; supports edge-triggered wake-up from HALT/STOP modes. |
| P07 | ANI0 / SI00 / RxD0 / KR2 / RTIO07 | Multi-function pin: analog input channel 0, SPI data input, UART receive, key return, or real-time output channel 7. |
| P10 | ANI1 / SCK00 / PCLBUZ0 / KR3 / SO00 / TxD0 | Shared functions include SPI clock, programmable clock/buzzer output, key return, SPI data output, and UART transmit. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11W68DSM#30 | 8 KB flash, 1 KB RAM; identical pinout, package, and peripheral set. | Supports larger firmware images and more complex control algorithms. | Select when firmware size exceeds 4 KB or additional RAM is needed for buffering or communication stacks. |
| R5F11Y67DSM#30 | RL78/G1N variant: higher drive strength (−130 mA total IOH), no RTIO, different pin function mapping (e.g., P15 lacks INTP2). | Optimized for segment LCD driving and high-current I/O; unsuitable where real-time output is required. | Choose only if application requires higher sink current and does not depend on RTIO or exact RL78/G1M peripheral configuration. |
Compared with R5F11W68DSM#30 and R5F11Y67DSM#30, the R5F11W67DSM#30 provides optimal balance of cost, power efficiency, and real-time output capability for mid-complexity industrial control - offering 4 KB flash at lower gate count than the 8 KB variant while retaining RTIO functionality absent in the G1N series.

FAQ
What is the maximum operating frequency of the R5F11W67DSM#30?
The R5F11W67DSM#30 supports a maximum high-speed on-chip oscillator frequency of 20 MHz, enabling a minimum instruction execution time of 0.05 µs under 2.7–5.5 V supply conditions. Its actual system clock (fMAIN) is configurable via option byte settings to select 1.25, 2.5, 5, 10, or 20 MHz - all with ±2% accuracy across −20°C to +85°C.
Does the R5F11W67DSM#30 support real-time output functionality?
Yes, the R5F11W67DSM#30 supports 8 real-time output (RTIO) channels, a feature exclusive to the RL78/G1M group. These channels generate precise, CPU-independent waveforms on designated pins (e.g., RTIO00–RTIO07), making the R5F11W67DSM#30 suitable for applications requiring jitter-free timing such as motor commutation or LED strobing.
What are the key differences between R5F11W67DSM#30 and R5F11W68DSM#30?
The R5F11W67DSM#30 and R5F11W68DSM#30 share identical package, pinout, peripherals, and operating specifications - differing only in memory capacity: R5F11W67DSM#30 has 4 KB flash and 512 B RAM, while R5F11W68DSM#30 offers 8 KB flash and 1 KB RAM. Both are drop-in replacements for footprint and interface design.
Can the R5F11W67DSM#30 operate from a 3.3 V supply?
Yes, the R5F11W67DSM#30 operates reliably from a 3.3 V supply within its specified 2.25–5.5 V range. At 3.3 V, it achieves full 20 MHz operation with ±2% oscillator accuracy, supports all I/O functions including N-ch open-drain outputs, and maintains HALT mode current ≤640 µA and STOP mode current ≤2.35 µA - ideal for 3.3 V industrial systems.
Is on-chip debug supported on the R5F11W67DSM#30?
Yes, the R5F11W67DSM#30 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. Debug access uses the TOOL0 pin and requires no external debug header. However, Renesas cautions against using this feature in mass-production firmware due to potential flash endurance impact from repeated programming cycles.
