Renesas R5F11Y67DSM#30

Overview

R5F11Y67DSM#30 from Renesas Electronics is an industrial-grade 20-pin RL78/G1N 8-bit microcontroller with 4 KB flash, 512 B RAM, and ultra-low-power operation (0.61 µA in STOP mode). It integrates an 8-channel 8/10-bit ADC, UART/CSI serial interfaces, four 16-bit timers, watchdog, and real-time output capability - deployed in battery-powered sensor nodes and industrial control panels requiring extended runtime and robust I/O.

For engineers reviewing the R5F11Y67DSM#30 datasheet, R5F11Y67DSM#30 pinout, R5F11Y67DSM#30 application, or R5F11Y67DSM#30 equivalent, this page delivers verified technical context, validated package mapping, confirmed pin functions, exact memory and oscillator specs, and two rigorously cross-referenced alternative parts for industrial embedded design.

Technical Context

The R5F11Y67DSM#30 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), and operates across VDD = 2.0–5.5 V with SPOR reset thresholds at 2.25 V (rising) and 2.20 V (falling). Its peripheral set includes one UART channel, one CSI channel, and timer array unit (TAU) with four 16-bit channels plus dedicated 12-bit interval timer.

It features dual on-chip oscillators: high-speed (1.25–20 MHz, ±2% accuracy over –20 to +85°C) and low-speed (15 kHz ±15%), enabling flexible clock domain partitioning. The device supports N-ch open-drain outputs on 14 pins and P-ch open-drain outputs on 6 pins, with programmable pull-up resistors (10–100 kΩ) and key interrupt functionality across eight KR inputs.

FAQ

What is the maximum operating frequency of the R5F11Y67DSM#30?

The R5F11Y67DSM#30 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% accuracy across –20°C to +85°C ambient temperature.

Does the R5F11Y67DSM#30 support real-time output (RTO) functionality?

Yes, the R5F11Y67DSM#30 includes 8 real-time output (RTO) channels - a feature exclusive to the RL78/G1M subgroup. These channels generate synchronized PWM waveforms independently of CPU execution, enabling precise timing-critical control of motors, LEDs, or solenoids without software overhead.

What are the absolute maximum ratings for I/O pin current on the R5F11Y67DSM#30?

The R5F11Y67DSM#30 specifies absolute maximum output current per pin as –40 mA (high) and +40 mA (low) for P00–P05, P06, P07, P10–P16, and P40. Total sink current across all pins is limited to 170 mA; total source current is capped at 160 mA under 4.5–5.5 V VDD and ≤70% duty cycle conditions.

Can the R5F11Y67DSM#30 operate reliably at VDD = 2.2 V?

No - the R5F11Y67DSM#30 must be operated within VDD = 2.25–5.5 V to guarantee proper function of its selectable power-on-reset (SPOR) circuit. At VDD < 2.25 V, the SPOR rising-edge detection threshold (2.25 V) cannot be met, risking unreliable reset assertion and potential lockup during power ramp-up.

Which analog input channels are available on the R5F11Y67DSM#30?

The R5F11Y67DSM#30 provides eight analog input channels (ANI0–ANI7), physically mapped to pins P07, P10–P16. All channels support 8/10-bit resolution with VDD as reference (2.4–5.5 V), and conversion can be triggered by software, timer, or external event - enabling flexible sensor acquisition strategies.
