Product details
Overview
R5F101LJDFB#V0 from Renesas is a 64-pin LFQFP-0.5 mm pitch, 192 KB flash, 8 KB data flash, 16 KB RAM RL78/G13 16-bit microcontroller with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V operation, and integrated 10-bit ADC (26 channels), RTC, UART, I²C, and SPI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101LJDFB#V0 datasheet, R5F101LJDFB#V0 pinout, R5F101LJDFB#V0 application, or R5F101LJDFB#V0 equivalent, key selection criteria include its 64-pin LFQFP package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for background data flash rewriting via BGO.
Technical Context
The R5F101LJDFB#V0 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, real-time clock with calendar/alarm functions, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timers, 2–4 channel DMA controller, and serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C/Simplified I²C - all configurable for mixed-voltage I/O (1.8/2.5/3.0 V interface capability).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response in resource-constrained embedded systems. |
| Flash Memory | 192 KB code flash (block size 1 KB); supports self-programming with boot swap and flash shield window security. |
| Data Flash | None (R5F101x series); eliminates data retention risk during firmware updates but requires external nonvolatile storage for configuration logging. |
| RAM | 16 KB on-chip RAM; sufficient for real-time control stacks, communication buffers, and sensor fusion algorithms. |
| Power Consumption | 66 μA/MHz active current; reduces battery drain in always-on monitoring applications without compromising processing throughput. |
| Operating Voltage | 1.6 V to 5.5 V single supply; simplifies power design across diverse input sources including coin cells and unregulated wall adapters. |
| Temperature Range | -40°C to +85°C (industrial D-grade); validated for deployment in factory automation, HVAC controls, and outdoor metering equipment. |
Pinout & Package
Package: 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 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 independent noise filtering per domain. |
| P10/P11/P12 | SPI0 SCK/SI/SO | Hardware CSI0 interface pins; enable synchronous serial communication with sensors or displays without CPU overhead. |
| P30/P31 | UART0 TX/RX | Full-duplex asynchronous serial interface; supports LIN bus physical layer compliance with programmable baud rate generation. |

| P60–P67 | RTC/CLKOUT/INT | Real-time clock crystal oscillator pins (32.768 kHz), clock output, and external interrupt inputs; enable time-stamped event logging and wake-from-HALT triggers. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power HALT/STOP/SNOOZE modes | Enables sub-μA sleep states while retaining RAM content and RTC operation - critical for multi-year battery life in wireless sensors. |
| Background Operation (BGO) for data flash | Permits concurrent program execution and flash rewrite; avoids system freeze during field firmware updates or parameter saves. |
| On-chip voltage detector (LVD) | 14-level selectable reset/interrupt threshold; protects against brown-out corruption in unstable power environments like solar-charged systems. |
| Multiply-accumulate (MAC) unit | 16×16→32-bit signed/unsigned multiply + 32-bit add; accelerates digital filter and motor control loop calculations without software overhead. |
| DMA controller (4 channels) | Transfers data between peripherals and RAM in 2 clocks per 8/16-bit word; offloads CPU during ADC streaming or UART buffering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LJDFB#V0 | Includes 8 KB on-chip data flash; same pinout, package, and peripheral set. | Preferred where firmware must store calibration data or user settings internally without external EEPROM. | Select when nonvolatile parameter storage is required and 8 KB data flash suffices for retention needs. |
| R5F101LJAFB#V0 | 48-pin LQFP variant; identical core, memory, and peripherals but reduced I/O count (42 vs. 52 GPIO). | Better suited for space-constrained designs with fewer analog/digital interfaces and no RTC crystal requirement. | Choose for cost-optimized, smaller-footprint implementations where full 64-pin I/O and RTC accuracy are not mandatory. |
Compared with R5F100LJDFB#V0, the R5F101LJDFB#V0 trades data flash for lower cost and simplified BOM, while R5F101LJAFB#V0 reduces pin count and package size - enabling trade-offs between nonvolatile storage, board area, and peripheral scalability.

What is the operating temperature range for the R5F101LJDFB#V0?
The R5F101LJDFB#V0 is rated for industrial operation from -40°C to +85°C (D-grade), as indicated by the 'D' in its part number suffix. This qualification ensures reliable performance in factory automation, building controls, and outdoor metering applications under extended thermal stress.
How many analog input channels does the R5F101LJDFB#V0 support?
The R5F101LJDFB#V0 features a 10-bit successive approximation A/D converter with up to 26 analog input channels (ANI0–ANI25), including internal temperature sensor and 1.45 V reference voltage. Channel selection is software-configurable, and conversions can be triggered by timers or external events.
Is the R5F101LJDFB#V0 pin-compatible with other RL78/G13 devices?
Yes, the R5F101LJDFB#V0 shares identical pinout and package (64-pin LFQFP, 0.5 mm pitch) with all other R5F101Lx variants (e.g., R5F101LJAFB#V0, R5F101LJDFB#V0, R5F101LJGFB#V0) and matches R5F100Lx devices in footprint and signal assignment - enabling hardware reuse across flash/data flash/performance variants.
