Product details
Overview
R5F101FLDFP#30 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6–5.5 V. It delivers 41 DMIPS, features ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (24 channels), dual UART/LIN, I²C, CSI, and real-time clock - deployed in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101FLDFP#30 datasheet, R5F101FLDFP#30 pinout, R5F101FLDFP#30 application, or R5F101FLDFP#30 equivalent, key selection criteria include its 44-pin LQFP package, absence of on-chip data flash (R5F101x series), industrial-grade -40°C to +85°C operation, and integrated LIN-capable UART for automotive body electronics and HVAC control systems.
Technical Context
The R5F101FLDFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 24-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, and 2× CSI (SPI-compatible) channels - all configurable via register-level control without external timing components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time control at 32 MHz with 41 DMIPS performance. |
| Flash Memory | 96 KB code flash (1 KB block size); supports self-programming with boot swap and flash shield window for firmware updates. |
| Data Flash | None (R5F101x series); eliminates data retention risk during power loss but requires external EEPROM or FRAM for nonvolatile parameter storage. |
| RAM | 8 KB on-chip RAM; sufficient for RTOS stacks, communication buffers, and sensor fusion algorithms in compact embedded designs. |
| ADC | 10-bit resolution, 24 analog inputs, internal 1.45 V reference and temperature sensor; enables direct thermal monitoring and multi-sensor signal acquisition. |
| Operating Voltage | 1.6 V to 5.5 V single supply; allows direct interface with 1.8 V, 3.3 V, and 5 V peripherals without level shifters. |
| Low-Power Modes | HALT (66 μA/MHz), STOP (0.57 μA with RTC+LVD active); extends battery life in always-on sensing applications beyond 5 years. |
Pinout & Package
Package: 44-pin LQFP (10 × 10 mm, 0.8-mm pitch), RoHS-compliant, moisture sensitivity level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual VDD/VSS pairs ensure stable core and I/O rail decoupling; supports noise-immune operation in motor-drive adjacent layouts. |
| P10/SCK00/SCL00 | Port 10 / SPI clock / I²C clock | Multi-function pin enabling shared hardware resources between SPI and I²C peripherals - reduces PCB routing complexity. |
| P11/SI00/RxD0/TOOLRxD/SDA00 | Port 11 / SPI input / UART0 RX / debug RX / I²C data | Combines serial debug (TOOLRxD), LIN/UART receive, and I²C data on one pin - simplifies programming and diagnostics in space-constrained designs. |
| P12/SO00/TxD0/TOOLTxD/SDA10 | Port 12 / SPI output / UART0 TX / debug TX / I²C data | Enables full-duplex UART/LIN communication and I²C master/slave operation while retaining debug visibility via TOOLTX. |
| P13/INTP0/ANI3 | Port 13 / external interrupt / ADC channel 3 | Hardware interrupt trigger with analog input capability - ideal for wake-on-event sensor interfaces with simultaneous voltage monitoring. |
| RESET | Active-low reset input | Accepts external reset signals and integrates with on-chip POR/LVD; ensures reliable startup under brown-out conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power HALT/STOP modes | Reduces system standby current to 0.57 μA with RTC and LVD active - critical for energy-harvesting and coin-cell-powered devices. |
| LIN-capable UART0 | Supports LIN 2.2 protocol natively; eliminates need for external LIN transceivers in automotive body control modules and HVAC nodes. |
| Background Data Flash Operation | Not applicable (R5F101x series lacks data flash); design must allocate external nonvolatile memory for configuration storage. |
| On-chip temperature sensor | Calibrated 10-bit ADC channel with ±2°C accuracy over -40°C to +85°C; enables thermal derating and ambient compensation without external ICs. |
| Real-time clock with calendar | 99-year calendar, alarm, and clock correction; provides timestamped logging and scheduled wake-up for periodic sensor sampling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100FLDFP#30 | Includes 8 KB data flash; same 96 KB code flash, 8 KB RAM, and identical pinout/package. | Preferred where field-updatable calibration tables or event logs must be stored internally without external memory. | Select when nonvolatile parameter storage is required and BOM cost increase for data flash is acceptable. |
| R5F101GLDFP#30 | 128 KB code flash, 8 KB RAM, same 44-pin LQFP package; no data flash. | Better suited for feature-rich firmware (e.g., OTA update stack + GUI framework) where code growth exceeds 96 KB. | Choose when future firmware expansion headroom is needed and pin compatibility must be preserved. |
Compared with R5F101FLDFP#30, R5F100FLDFP#30 adds data flash at higher unit cost and slightly higher active current, while R5F101GLDFP#30 trades flash density for scalability - both retain identical peripheral sets, low-power behavior, and industrial temperature rating.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101FLDFP#30?
The R5F101FLDFP#30 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS performance. This value is measured per the EEMBC CoreMark benchmark and reflects real-world throughput for mixed-control-and-data-processing tasks in the RL78/G13 architecture.
Does the R5F101FLDFP#30 include on-chip data flash memory?
No, the R5F101FLDFP#30 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number, it belongs to the R5F101x series, which omits data flash. Designers must use external nonvolatile memory (e.g., SPI EEPROM or FRAM) for configuration storage or logging.
What are the supported low-power modes and their typical current consumption for R5F101FLDFP#30?
The R5F101FLDFP#30 supports HALT mode (66 μA/MHz) and STOP mode (0.57 μA with RTC and LVD active). These values are specified at VDD = 3.0 V and TA = 25°C. The STOP mode enables multi-year battery operation in applications like wireless sensors and utility meters.
Which communication interfaces are integrated into the R5F101FLDFP#30?
The R5F101FLDFP#30 integrates two UART/LIN channels (one supports LIN 2.2), three I²C/Simplified I²C channels, and two CSI (SPI-compatible) channels. All interfaces operate independently and can be used concurrently - for example, UART0 for LIN bus, I²C for sensor readout, and CSI for display driver control.
What is the ADC resolution, channel count, and reference voltage option for R5F101FLDFP#30?
The R5F101FLDFP#30 features a 10-bit successive-approximation ADC with up to 24 input channels. It supports internal 1.45 V reference voltage and external reference inputs. The internal reference is factory-calibrated and usable across the full -40°C to +85°C temperature range without external components.
