Product details
Overview
R5F11Y68DSM#30 from Renesas Electronics is an 8 KB flash, 512 B RAM RL78/G1N-series 20-pin TSSOP microcontroller operating at 2.0–5.5 V, featuring a 20 MHz high-speed on-chip oscillator (±2% accuracy), 8-channel 8/10-bit ADC, UART/CSI serial interfaces, and 4-channel 16-bit timer array - deployed in industrial sensor nodes requiring low-power operation and deterministic real-time control.
For engineers reviewing the R5F11Y68DSM#30 datasheet, R5F11Y68DSM#30 pinout, R5F11Y68DSM#30 application, or R5F11Y68DSM#30 equivalent, this page delivers verified package mapping (20-pin TSSOP), confirmed I/O count (18 total, including 14 N-ch open-drain), validated supply current specs (0.61 µA STOP mode @ 3 V), and two documented alternative parts with functional alignment for industrial-grade embedded designs.
Technical Context
The R5F11Y68DSM#30 implements the RL78-S1 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.05 µs (@20 MHz) to 0.8 µs (@1 MHz). Its peripheral set includes a 12-bit interval timer, watchdog timer, and programmable clock/buzzer output (PCLBUZ0) with frequency range 2.44 kHz–10 MHz.
It integrates selectable power-on-reset (SPOR) with four rising-edge detection thresholds (2.25/2.68/3.02/4.45 V), supports key interrupt on KR0–KR7 pins, and enables peripheral I/O redirection via PIOR register - allowing dynamic assignment of functions like RxD0/TxD0/SCK00 across multiple pins without hardware change.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78-S1 CISC with 3-stage pipeline; enables deterministic timing for real-time control loops. |
| Flash / RAM | 8 KB code flash + 512 B on-chip RAM; sufficient for compact firmware with integrated ADC calibration routines. |
| Operating Voltage | 2.0–5.5 V supply range; usable down to 2.25 V due to SPOR circuit constraints - critical for brown-out resilience. |
| Max Clock Frequency | 20 MHz high-speed on-chip oscillator (±2% over –20 to +85°C); eliminates external crystal for cost-sensitive industrial modules. |
| ADC Resolution | 8/10-bit SAR A/D converter with 8 analog inputs; supports simultaneous sampling of temperature, voltage, and current sensors. |
| Serial Interfaces | 1 UART channel + 1 CSI channel; enables direct RS-485 transceiver interfacing and SPI-compatible sensor communication. |
| Supply Current (STOP) | 0.61 µA @ VDD = 3 V, TA = 25°C; enables multi-year battery life in wireless sensor endpoints. |
Pinout & Package
Package: 20-pin plastic TSSOP (4.4 × 6.5 mm, 0.65 mm pitch), industrial-grade (D-suffix), tray packaging (#30).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | Main 2.0–5.5 V supply rail; decoupling capacitor required per Renesas layout guidelines. |
| VSS | Ground | Digital ground reference; must be connected to system GND plane with low-inductance path. |
| P00–P05 | CMOS I/O (N-ch open-drain) | 14 total N-ch open-drain outputs with VDD tolerance; suitable for driving LEDs or optocouplers directly. |
| P06, P07, P10–P16, P40 | CMOS I/O (N-ch open-drain) | Additional N-ch open-drain pins; P06/P10 do not output high level in N-ch mode - requires external pull-up. |
| 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 and timer input; supports edge-triggered wake-up from HALT/STOP modes. |
| ANI0–ANI7 | Analog inputs | 8-channel ADC inputs; support single-ended measurement with internal reference (VDD or AVREF). |
| RxD0 / TxD0 | UART data I/O | Asynchronous serial interface; supports baud rates up to 3.3 Mbps with dedicated baud rate generator. |
| SCK00 / SI00 / SO00 | CSI interface | 3-wire synchronous serial interface; configurable as master (internal clock) or slave (external clock). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power STOP mode | 0.61 µA typical current draw enables >10-year battery life in maintenance-free sensor nodes. |
| Selectible SPOR detection voltage | Four thresholds (2.25/2.68/3.02/4.45 V) allow precise brown-out recovery tuning for varying supply profiles. |
| Peripheral I/O redirection (PIOR) | Runtime remapping of UART/CSI/Timer functions across multiple pins - reduces PCB redesign risk during prototyping. |
| On-chip BCD correction | Hardware-accelerated decimal arithmetic support simplifies display driver firmware for industrial HMI panels. |
| Real-time output capability | Not implemented in RL78/G1N series - distinguishes R5F11Y68DSM#30 from RL78/G1M variants with RTIO channels. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11Y67DSM#30 | 4 KB flash / 512 B RAM vs. 8 KB / 512 B; identical pinout, peripherals, and voltage specs. | Lower firmware footprint requirement; insufficient for OTA update partitions or complex sensor fusion algorithms. | Select when firmware size ≤ 3.5 KB and no future feature expansion is planned. |
| R5F11W68DSM#30 | RL78/G1M variant with real-time output (RTIO) channels; same flash/RAM but lacks high-current P-ch open-drain outputs. | Required for applications needing synchronized PWM outputs (e.g., motor phase control); unsuitable for high-side load switching. | Choose only if RTIO functionality is mandatory and P-ch drive capability is unnecessary. |
Compared with R5F11Y67DSM#30, the R5F11Y68DSM#30 provides double flash capacity for secure bootloader + application partitioning; versus R5F11W68DSM#30, it trades RTIO for industrial-grade N-ch open-drain drive strength - making it optimal for sensor aggregation and relay control where deterministic I/O timing outweighs PWM synchronization needs.

FAQ
What is the maximum operating frequency of the R5F11Y68DSM#30?
The R5F11Y68DSM#30 supports a maximum high-speed on-chip oscillator frequency of 20 MHz, with ±2% accuracy over –20 to +85°C ambient temperature. This allows minimum instruction execution time of 0.05 µs under 20 MHz operation, enabling tight real-time control loops without external clock components. The R5F11Y68DSM#30 does not require an external crystal for basic timing-critical functions.
Does the R5F11Y68DSM#30 support real-time output (RTIO) functionality?
No, the R5F11Y68DSM#30 does not implement real-time output (RTIO) channels. RTIO is exclusive to the RL78/G1M series (e.g., R5F11W68DSM#30). The R5F11Y68DSM#30 belongs to the RL78/G1N family, which omits RTIO but adds enhanced N-ch open-drain output capability - confirmed in Section 1.6 of the R01DS0378EJ0100 datasheet.
What are the absolute maximum ratings for output current on R5F11Y68DSM#30 I/O pins?
Per the R01DS0378EJ0100 datasheet, the R5F11Y68DSM#30 has absolute maximum output current ratings of –40 mA per pin (high) and +40 mA per pin (low) for P00–P05, P06, P07, P10–P16, and P40. Total sink current across all pins is limited to 170 mA, and total source current is capped at 160 mA under 4.5–5.5 V operation - critical for relay or LED driver design validation.
Can the R5F11Y68DSM#30 operate from a 2.0 V supply?
The R5F11Y68DSM#30 is rated for 2.0–5.5 V operation, but Renesas specifies use within 2.25–5.5 V due to the selectable power-on-reset (SPOR) circuit's minimum detection voltage of 2.25 V. Operating below 2.25 V risks unreliable reset behavior and potential lockup - therefore, the practical lower limit for robust operation is 2.25 V, not 2.0 V, as explicitly stated in Notes 1 and 2 of Section 1.6.
Which serial interfaces are supported by the R5F11Y68DSM#30?
The R5F11Y68DSM#30 integrates one UART channel (RxD0/TxD0) and one CSI channel (SCK00/SI00/SO00), both configurable via peripheral I/O redirection register (PIOR). UART supports up to 3.3 Mbps theoretical transfer rate with dedicated baud rate generator; CSI operates in master or slave mode with programmable clock polarity and phase - enabling flexible connectivity to sensors, displays, and legacy industrial peripherals.
