Product details
Overview
R5F101LGDFA#X0 from Renesas is a 64-pin LQFP-0.65mm, 128 KB flash, no data flash, industrial-grade RL78/G13 16-bit MCU operating from 1.6–5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101LGDFA#X0 datasheet, R5F101LGDFA#X0 pinout, R5F101LGDFA#X0 application, or R5F101LGDFA#X0 equivalent, key selection criteria include its 64-pin LQFP package, absence of on-chip data flash, -40°C to +85°C industrial temperature rating, and support for UART/LIN, I²C, and 16-bit timers in resource-constrained embedded control designs.
Technical Context
The R5F101LGDFA#X0 implements the RL78 CPU core with a 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 an on-chip high-accuracy ±1.0% oscillator (selectable 1–32 MHz), 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 16 channels of 10-bit A/D converter (6–26 inputs), 8–16 channels of 16-bit timer, 2–4 UART/LIN interfaces, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) interfaces - all configurable without external components for deterministic real-time control in cost-sensitive industrial nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic interrupt latency and compact code footprint for firmware-limited applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGDFA#X0 | Includes 8 KB data flash; identical pinout, package, and peripheral set. | Preferred when field-updatable calibration data or event logs must be stored on-chip without external memory. | Select R5F100LGDFA#X0 if nonvolatile parameter storage is required; otherwise R5F101LGDFA#X0 reduces cost and simplifies firmware design. |
| RL78/G14 R5F104LGDFB#X0 | Enhanced RL78/G14 core; adds 32 KB data flash, higher max frequency (48 MHz), and CAN interface. | Suitable for CAN-based building automation or automotive body electronics where protocol compliance is mandatory. | Choose RL78/G14 only if CAN or larger data flash is essential; R5F101LGDFA#X0 remains optimal for LIN/UART-only industrial control. |
Compared with R5F100LGDFA#X0, this part removes data flash to reduce cost and die size while retaining identical code flash, RAM, peripherals, and industrial temperature rating; versus RL78/G14, it trades CAN and higher performance for lower power and proven G13 ecosystem compatibility.

FAQ
What is the flash memory configuration of the R5F101LGDFA#X0?
The R5F101LGDFA#X0 contains 128 KB of on-chip code flash memory with 1 KB erasable blocks and supports self-programming with boot swap functionality. It does not include integrated data flash memory - nonvolatile parameter storage must be implemented externally using EEPROM or FRAM.
Does the R5F101LGDFA#X0 support CAN bus communication?
No, the R5F101LGDFA#X0 does not support CAN bus. It provides UART/LIN, I²C, and CSI (SPI-compatible) interfaces. For CAN-capable alternatives in the same family, consider the RL78/G14 series such as R5F104LGDFB#X0, which adds a CAN 2.0B controller alongside enhanced peripherals.
What is the operating temperature range for the R5F101LGDFA#X0?
The R5F101LGDFA#X0 is rated for industrial operation from -40°C to +85°C (D-grade qualification). This makes it suitable for deployment in factory automation equipment, HVAC systems, and outdoor metering enclosures without additional thermal derating.
How many analog input channels does the R5F101LGDFA#X0 support?
The R5F101LGDFA#X0 supports up to 26 analog input channels for its 10-bit A/D converter, including dedicated pins like P20/ANI0 and P21/ANI1. It also integrates an internal temperature sensor and 1.45 V reference voltage, enabling standalone thermal monitoring without external components.
Is the R5F101LGDFA#X0 pin-compatible with other RL78/G13 64-pin variants?
Yes, the R5F101LGDFA#X0 shares identical pinout and package (64-pin LQFP, 0.65-mm pitch) with all other RL78/G13 64-pin variants, including R5F100LGDFA#X0 and R5F101LCDFA#X0. Firmware and hardware designs can be reused across these parts with only flash/data flash configuration differences requiring attention.
