Product details
Overview
R5F11RMGDFB#30 from Renesas is an industrial-grade 80-pin RL78/H1D microcontroller featuring a 24 MHz RL78 CPU core (33 DMIPS), 128 KB flash, 8 KB RAM, and integrated external signal sampler (EXSDI/EXSDO) plus sampling output timer detector (SMOTD) for precision sensor interface. It operates from 1.8 V to 5.5 V, achieves 70.8 μA/MHz active power, and supports RTC2, LCD controller (36 seg × 8 com), and dual UART/I²C/SPI interfaces - deployed in flow metering and industrial sensor conditioning systems.
For engineers reviewing the R5F11RMGDFB#30 datasheet, R5F11RMGDFB#30 pinout, R5F11RMGDFB#30 application, or R5F11RMGDFB#30 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases in analog-intensive industrial measurement, and actionable alternative part guidance - all grounded in Renesas' official RL78/H1D documentation (R01DS0318EJ0111 Rev. 1.11).
Technical Context
The R5F11RMGDFB#30 implements the RL78 CISC core with 3-stage pipeline, supporting instruction execution times from 0.04167 µs (@24 MHz HS mode) to 30.5 µs (@32.768 kHz LS mode). Its dedicated external signal sampler accepts up to six EXSDI inputs synchronized to three SMO outputs, while SMOTD provides hardware-triggered sampling detection across six input channels and three output channels.
It integrates a 12-bit interval timer, RTC2 with calendar/alarm/correction, watchdog timer, and event link controller (ELC) enabling direct peripheral-to-peripheral signal routing without CPU intervention - critical for deterministic low-latency sensor acquisition in industrial control loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RL78 CISC, 33 DMIPS @ 24 MHz - enables real-time sensor fusion and protocol stack execution within tight timing budgets. |
| Flash / RAM | 128 KB code flash + 4 KB data flash + 8 KB RAM - supports firmware updates via BGO and complex calibration tables in field-deployed devices. |
| Operating Voltage | 1.8 V to 5.5 V - ensures compatibility with battery-powered, 3.3 V, and 5 V industrial sensor nodes without level-shifting. |
| Power Consumption | 70.8 μA/MHz active, 0.68 μA Halt mode - extends battery life in portable flow meters and reduces thermal load in sealed enclosures. |
| Sampling Interface | 6-channel EXSDI input + 3-channel EXSDO clock output + 6-in/3-out SMOTD - enables synchronous multi-sensor capture (e.g., ultrasonic transit-time pairs) with hardware timestamping. |
| LCD Driver | 36 segment × 8 common outputs with internal boost/CAPL/CAPH support - drives segmented displays in panel-mounted instrumentation without external bias circuitry. |
| Peripherals | 3 UART, 4 I²C, 3 CSI (SPI), 8-channel TAU timer, RTC2, ELC, DTC - consolidates communication, timing, and data movement for compact industrial HMI designs. |
Pinout & Package
Package: 80-pin LFQFP (12 × 12 mm, 0.5 mm pitch), industrial temperature grade (−40°C to +85°C), lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P20–P27 | Port 2 I/O | Dedicated SMP0–SMP5 sampling inputs plus INTP2–INTP7 interrupt sources - directly connect analog front-end outputs for hardware-triggered acquisition. |
| P84–P86, P150–P151 | SMO0–SMO2, SMP0–SMP3 | Sampling clock outputs (SMO) and additional sampling inputs (SMP) - synchronize multiple transducers or external ADCs with precise phase alignment. |
| P80–P83 | TRJO0/TRJO1, EXSDO0/EXSDO1 | Timer RJ outputs and external sampling clock outputs - generate programmable sampling strobes independent of main CPU clock domain. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11RMJDFB#30 | Same 80-pin LFQFP package and RL78/H1D core, but with 96 KB flash and 5.5 KB RAM instead of 128 KB/8 KB. | Suitable for cost-sensitive flow meters with smaller firmware footprints and no need for extensive calibration storage. | Select when BOM cost reduction is prioritized over future firmware scalability and large sensor coefficient tables. |
| R5F11RMDDB#30 | Identical 128 KB flash/8 KB RAM spec and EXSDI/SMOTD peripherals, but in 64-pin TFBGA (4 × 4 mm) instead of 80-pin LFQFP. | Targeted at space-constrained portable analyzers where PCB area is premium and thermal dissipation is managed via ground plane design. | Choose for miniaturized designs requiring same functionality in smaller footprint - verify layout compatibility with TFBGA reflow profile and test access. |
Compared with R5F11RMGDFB#30, R5F11RMJDFB#30 trades flash/RAM capacity for lower unit cost in volume production, while R5F11RMDDB#30 preserves full feature parity in a compact TFBGA package - enabling either cost-optimized or space-constrained industrial sensor node variants from the same software base.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F11RMGDFB#30?
The R5F11RMGDFB#30 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 33 DMIPS performance. This is confirmed in the RL78/H1D datasheet (R01DS0318EJ0111 Rev. 1.11, Page 1) and enables real-time execution of sensor fusion algorithms and communication stacks without external acceleration. The R5F11RMGDFB#30 maintains this performance across its full industrial temperature range (−40°C to +85°C).
Does the R5F11RMGDFB#30 include a 24-bit delta-sigma ADC or programmable gain amplifier (PGA)?
No, the R5F11RMGDFB#30 does not include a 24-bit ΔΣ ADC or PGA. Those features are exclusive to the R5F11N and R5F11P variants (e.g., R5F11NMG). The R5F11RMGDFB#30 belongs to the "R" subfamily, which emphasizes external signal sampling (EXSDI/SMOTD) and timer-based measurement - it retains only the 10-bit SAR ADC (3 channels) as specified in Section 1.1 of the R01DS0318EJ0111 datasheet.
What are the key differences between R5F11RMGDFB#30 and R5F11RMDDB#30?
The R5F11RMGDFB#30 and R5F11RMDDB#30 share identical core specifications (128 KB flash, 8 KB RAM, EXSDI/SMOTD, RTC2, LCD driver), but differ in package: R5F11RMGDFB#30 uses 80-pin LFQFP (12 × 12 mm), while R5F11RMDDB#30 uses 64-pin TFBGA (4 × 4 mm). The TFBGA variant reduces PCB area by ~85% but requires different layout, thermal, and test strategies. Both are rated for industrial temperature range (−40°C to +85°C).
Can the R5F11RMGDFB#30 drive a 4×32 segment LCD without external components?
Yes, the R5F11RMGDFB#30 integrates a full LCD controller/driver supporting up to 36 segments × 8 commons. It includes internal voltage boosting, capacitor-split, and external resistor-division methods - allowing direct drive of multiplexed LCDs like 4×32 segment displays without external bias generators or charge pumps. Configuration is done via dedicated LCD registers, and VL1–VL4 pins provide adjustable contrast control per the RL78/H1D datasheet (Page 2).
What power modes does the R5F11RMGDFB#30 support, and what is its lowest current draw?
The R5F11RMGDFB#30 supports HALT, STOP, and SNOOZE modes. Its lowest current draw is 0.68 μA in HALT mode with RTC2 and LVD enabled - verified in the RL78/H1D datasheet (R01DS0318EJ0111 Rev. 1.11, Page 1). This ultra-low quiescent current enables multi-year battery life in portable flow meters and wireless sensor nodes, with wake-up via EXSDI edges, timer interrupts, or external pins.
