Product details
Overview
R5F11Y68DSM#10 from Renesas Electronics is an 8 KB flash, 1 KB RAM RL78/G1N 20-pin TSSOP microcontroller optimized for industrial sensor nodes and low-power control applications. It features an ultra-low-power HALT/STOP mode (0.61 µA in STOP), 8-channel 10-bit A/D converter, UART/CSI serial interfaces, and 4-channel 16-bit timer with PWM output capability.
For engineers reviewing the R5F11Y68DSM#10 datasheet, R5F11Y68DSM#10 pinout, R5F11Y68DSM#10 application, or R5F11Y68DSM#10 equivalent, key selection criteria include industrial-grade temperature range (−40°C to +85°C), VDD = 2.0–5.5 V operation with SPOR reset options, and N-ch/P-ch open-drain I/O support for direct LED/display driving.
Technical Context
The R5F11Y68DSM#10 implements the RL78-S1 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.05 µs (20 MHz) to 0.8 µs (1 MHz). Its memory subsystem includes 8 KB on-chip flash with on-chip debug, 1 KB RAM, and a selectable power-on-reset circuit with four detection voltage thresholds (2.25 V to 4.45 V).
Peripherals are tightly integrated via a unified peripheral I/O redirection register (PIOR), enabling dynamic assignment of functions like UART0 (RxD0/TxD0), CSI0 (SI00/SO00/SCK00), and real-time output channels. The high-speed on-chip oscillator delivers ±2.0% accuracy across −20°C to +85°C at 20 MHz, while the low-speed oscillator runs at 15 kHz ±15% for watchdog and interval timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RL78-S1 8-bit CISC with 3-stage pipeline; enables deterministic real-time control with minimal code footprint. |
| Flash / RAM | 8 KB code flash + 1 KB RAM; sufficient for standalone sensor firmware with calibration tables and communication stacks. |
| Operating Voltage | VDD = 2.0–5.5 V; supports wide-input industrial power rails and battery-backed operation down to 2.25 V (SPOR limit). |
| A/D Converter | 8-channel, 10-bit resolution (VDD = 2.4–5.5 V); enables direct analog sensing of temperature, voltage, or current without external ADC. |

| 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 or timer input; used for edge-triggered wake-up or pulse-width measurement. |
| P07, P10 | RxD0 / TxD0 | UART0 full-duplex interface; supports asynchronous communication at up to 3.3 Mbps with hardware baud rate generation. |
| P15, P14, P10 | ANI6 / ANI5 / ANI1 | Analog inputs for 10-bit A/D conversion; share pins with digital I/O and require dedicated sampling time per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power STOP mode | 0.61 µA typical (VDD = 3.0 V); enables multi-year battery life in intermittent-sensing applications. |
| Selectable SPOR voltage | Four thresholds (2.25 V/2.68 V/3.02 V/4.45 V); allows precise brown-out detection matching system power rail behavior. |
| On-chip BCD correction | Hardware-accelerated decimal arithmetic; reduces firmware overhead in display-driven metering applications. |
| Peripheral I/O redirection | PIOR register enables runtime remapping of UART/CSI/timer pins to alternate GPIOs; increases PCB layout flexibility. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11Y67DSM#10 | 4 KB flash / 512 B RAM; identical package, peripherals, and voltage/temp specs. | Suitable for simpler firmware with smaller code size; lower memory density reduces cost where feature set is unchanged. | Select when application firmware fits within 4 KB and no future expansion is planned. |
| R5F11W68DSM#10 | RL78/G1M variant: adds 8-channel real-time output (RTIO); same 8 KB/1 KB memory and TSSOP-20 package. | Required for applications needing synchronized multi-channel waveform generation (e.g., lighting control, audio DAC timing). | Choose only if RTIO functionality is explicitly needed; otherwise R5F11Y68DSM#10 offers identical core performance at lower unit cost. |
Compared with R5F11Y67DSM#10, the R5F11Y68DSM#10 provides double flash/RAM for complex protocols or OTA updates; versus R5F11W68DSM#10, it omits RTIO but retains all other peripherals-making it optimal for general-purpose industrial control where timing synchronization is not critical.

FAQ
What is the maximum operating frequency of the R5F11Y68DSM#10?
The R5F11Y68DSM#10 supports a maximum high-speed on-chip oscillator frequency of 20 MHz, delivering a minimum instruction execution time of 0.05 µs under VDD ≥ 2.7 V. This frequency is selectable via option byte bits 0–2 and remains stable within ±2.0% accuracy across −20°C to +85°C ambient conditions.
Does the R5F11Y68DSM#10 support UART communication at 3.3 Mbps?
Yes, the R5F11Y68DSM#10 achieves a theoretical maximum UART transfer rate of 3.3 Mbps when the main system clock (fMCK) is set to 20 MHz. This requires proper configuration of the dedicated baud rate generator and adherence to AC timing specifications for RX/TX signal integrity.
How many analog input channels does the R5F11Y68DSM#10 have?
The R5F11Y68DSM#10 integrates an 8-channel, 10-bit A/D converter with input pins ANI0 through ANI7. These channels are multiplexed onto physical pins P07, P10–P16, and P11, and operate over a VDD-referenced range of 2.4 V to 5.5 V.
What is the STOP mode current consumption of the R5F11Y68DSM#10?
The R5F11Y68DSM#10 draws 0.61 µA typical supply current in STOP mode at VDD = 3.0 V and TA = 25°C. This value rises to 2.35 µA maximum across the full −40°C to +85°C temperature range, enabling multi-year operation in battery-powered industrial sensors.
Is the R5F11Y68DSM#10 pin-compatible with the R5F11W68DSM#10?
No-the R5F11Y68DSM#10 and R5F11W68DSM#10 share the same 20-pin TSSOP package and pin count but differ in peripheral mapping: R5F11W68DSM#10 includes real-time output (RTIO) functionality and different I/O drive characteristics, while R5F11Y68DSM#10 emphasizes high-current P-ch open-drain outputs for display driving.
