Product details
Overview
R5F101MLDFB#30 from Renesas is a 80-pin LFQFP, 0.5-mm pitch, industrial-grade (−40°C to +85°C) RL78/G13 16-bit MCU with 128 KB flash, 12 KB RAM, and no data flash memory. It delivers 41 DMIPS at 32 MHz, operates from 1.6 V to 5.5 V, and achieves ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), targeting battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F101MLDFB#30 datasheet, R5F101MLDFB#30 pinout, R5F101MLDFB#30 application, or R5F101MLDFB#30 equivalent, key selection considerations include its 80-pin LFQFP-0.5mm package, absence of on-chip data flash, industrial temperature rating, integrated 10-bit ADC (26 channels), real-time clock with calendar, and support for UART/LIN, I²C, and CSI serial interfaces.
Technical Context
The R5F101MLDFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 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, 16-bit timers (16 channels), watchdog timer, and DMA controller (4 channels) for deterministic peripheral handling.
Its analog subsystem includes a 10-bit A/D converter with up to 26 input channels, internal 1.45 V reference voltage, and temperature sensor-operable only in HS mode. Power management features HALT, STOP, and SNOOZE modes, on-chip POR, and LVD with 14 selectable voltage levels for robust system supervision.

FAQ
What is the maximum operating frequency and performance of the R5F101MLDFB#30?
The R5F101MLDFB#30 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. Its RL78 CPU core supports variable instruction timing-from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed mode-enabling dynamic trade-offs between throughput and power consumption in real-time applications.
Does the R5F101MLDFB#30 include on-chip data flash memory?
No, the R5F101MLDFB#30 does not include on-chip data flash memory. Per Renesas part numbering convention, the "101" prefix indicates data flash is omitted. This distinguishes it from "100"-series variants like R5F100MLDFB#30, which integrate 8 KB of data flash for parameter storage and firmware updates.
What package type and pin count does the R5F101MLDFB#30 use?
The R5F101MLDFB#30 uses an 80-pin LFQFP package with 0.5-mm pitch and 12 × 12 mm body size. The "FB" suffix in the part number explicitly denotes LFQFP, and the "ML" segment confirms the 80-pin configuration per Renesas RL78/G13 ordering nomenclature.
What is the operating temperature range for the R5F101MLDFB#30?
The R5F101MLDFB#30 is rated for industrial operation from −40°C to +85°C. Its "D" grade designation (embedded in the part number structure) certifies compliance with this extended temperature range, making it suitable for deployment in factory automation, outdoor metering, and harsh-environment control systems.
Which serial communication interfaces are supported by the R5F101MLDFB#30?
The R5F101MLDFB#30 supports three serial interface families: CSI (SPI-compatible, up to 8 channels), UART/LIN (up to 4 channels, including LIN bus support), and I²C/Simplified I²C (up to 10 channels). These are implemented in hardware with independent registers and interrupt vectors for concurrent multi-protocol operation.
