Product details
Overview
R5F101MLDFA#30 from Renesas is an RL78/G13 80-pin LQFP MCU with 128 KB flash, 12 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS). It integrates a 10-bit ADC (26 channels), real-time clock, UART/SPI/I²C interfaces, 16-bit timers, and ultra-low-power modes (0.57 μA in RTC+LVD mode) for battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F101MLDFA#30 datasheet, R5F101MLDFA#30 pinout, R5F101MLDFA#30 application, or R5F101MLDFA#30 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, industrial-grade −40°C to +85°C operation (D-grade), absence of on-chip data flash, and support for background data flash programming via external library - critical for firmware-over-the-air updates in field-deployed equipment.
Technical Context
The R5F101MLDFA#30 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). Its memory map spans 1 MB address space, with flash organized in 1 KB blocks and security features including block erase prohibition.
Power management includes on-chip POR and LVD with 14 selectable voltage thresholds, HALT/STOP/SNOOZE low-power modes, and DMA controller (4 channels) enabling efficient peripheral-to-memory transfers in 2 clocks per 8/16-bit SFR access - essential for deterministic real-time response in motor control and PLC I/O modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MLDFA#30 | Includes 8 KB data flash; same 128 KB code flash, 12 KB RAM, and pinout | Required where frequent nonvolatile parameter storage (e.g., calibration data, usage logs) is needed without external EEPROM | Select when data flash endurance (1M cycles) and background rewrite capability are mandatory for field-updatable systems |
| R5F101MLDFA#50 | Identical electrical specs and functionality; differs only in packaging (embossed tape vs. tray) | No functional difference; chosen based on SMT line feed requirements and volume procurement logistics | Choose #50 for high-volume automated assembly requiring tape-and-reel delivery; #30 remains optimal for prototyping and low-volume production |
Compared with R5F100MLDFA#30, the R5F101MLDFA#30 trades data flash for marginally lower cost and identical code density - ideal for fixed-parameter designs. Against R5F101MLDFA#50, it offers identical silicon but optimized for tray-based handling in pilot runs and engineering builds.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101MLDFA#30?
The R5F101MLDFA#30 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its high-accuracy on-chip oscillator maintains ±1.0% tolerance across 1.8–5.5 V and −20°C to +85°C, eliminating need for external crystal in many applications. This frequency enables real-time execution of motor control algorithms and protocol stacks while maintaining ultra-low active current (66 μA/MHz).
Does the R5F101MLDFA#30 include on-chip data flash memory?
No, the R5F101MLDFA#30 does not include on-chip data flash memory. The "101" in the part number explicitly denotes absence of data flash, distinguishing it from "100" variants (e.g., R5F100MLDFA#30) which integrate 8 KB. Applications requiring frequent nonvolatile parameter storage must use external EEPROM or leverage code flash with wear-leveling software - confirmed in Renesas documentation R01DS0131EJ0380 Section 1.1.
What package type and pin count does the R5F101MLDFA#30 use?
The R5F101MLDFA#30 uses an 80-pin LQFP package with 0.65-mm pitch (RENESAS Code PLQP0080JB-E), measuring 14 mm × 14 mm. This package is RoHS-compliant, supports standard reflow profiles, and provides full access to all 64 GPIOs, 26 ADC inputs, and multiple serial interfaces - verified in Table 1-1 (Page 11) and Figure 1-1 of the RL78/G13 datasheet R01DS0131EJ0380.
What industrial temperature grade is specified for the R5F101MLDFA#30?
The R5F101MLDFA#30 is rated for industrial operation from −40°C to +85°C (D-grade), as indicated by the "D" in the part number suffix per Figure 1-1 of R01DS0131EJ0380. It is not rated for the extended −40°C to +105°C (G-grade) range. This qualification ensures reliability in factory automation, building controls, and outdoor metering environments under sustained thermal stress.
How does the R5F101MLDFA#30 support low-power design in battery-operated systems?
The R5F101MLDFA#30 supports ultra-low-power design via multiple hardware features: STOP mode draws just 0.57 μA with RTC and LVD active; SNOOZE mode enables peripheral-triggered wake-up without full CPU restart; and HALT mode reduces current to 0.95 μA. Combined with 1.6 V minimum operating voltage and programmable LVD thresholds, these capabilities enable multi-year battery life in wireless sensors - validated in Section 1.1 "Ultra-low power consumption technology" of R01DS0131EJ0380.
