Product details
Overview
R5F101LLDFA#30 from Renesas is a 64-pin LQFP-0.65mm, 128 KB flash, 12 KB RAM, RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), real-time clock, 10-bit ADC (26 channels), and integrated UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101LLDFA#30 datasheet, R5F101LLDFA#30 pinout, R5F101LLDFA#30 application, or R5F101LLDFA#30 equivalent, key selection criteria include its 128 KB code flash with no data flash, -40°C to +85°C industrial temperature grade (D), LQFP-64 0.65-mm pitch package, RTC+LVD low-power retention mode (0.57 μA), and support for background data flash programming via BGO.
Technical Context
The R5F101LLDFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-mode RTC with alarm and clock correction, and a watchdog timer driven by a dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2–4× UART/LIN channels, 2–8× CSI (SPI-compatible) channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all operating across 1.6–5.5 V supply and -40°C to +85°C ambient range.

FAQ
What is the flash memory configuration of the R5F101LLDFA#30?
The R5F101LLDFA#30 contains 128 KB of code flash memory and no data flash memory - consistent with the R5F101x series designation. This configuration targets applications where firmware is static or updated via external memory, and eliminates data flash wear-out concerns. The R5F101LLDFA#30 uses the same flash block size (1 KB) and security features (block erase prohibition) as other RL78/G13 variants.
Does the R5F101LLDFA#30 support real-time clock functionality with calendar mode?
Yes, the R5F101LLDFA#30 integrates a full-featured real-time clock (RTC) with calendar mode supporting year/month/day/hour/minute/second, leap-year compensation, alarm interrupt, and clock correction. It operates independently in STOP mode with only 0.57 μA current draw when powered by VDD and backed by a 32.768 kHz crystal on RTC_IN/RTC_OUT pins.
What is the maximum operating frequency and associated power consumption of the R5F101LLDFA#30?
The R5F101LLDFA#30 operates up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C. At 32 MHz, its typical active current is 66 μA/MHz - resulting in ~2.1 mA total at full speed. In STOP mode with RTC and LVD active, it draws just 0.57 μA, enabling multi-year battery operation.
Which communication interfaces are available on the R5F101LLDFA#30?
The R5F101LLDFA#30 provides UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible serial interface, up to 8 channels). All interfaces are software-configurable and share pins with GPIO, allowing flexible peripheral assignment. No CAN or USB interfaces are integrated - those require external transceivers or bridge ICs.
Is the R5F101LLDFA#30 pin-compatible with other RL78/G13 64-pin variants?
Yes, the R5F101LLDFA#30 shares identical pinout and package (LQFP-64, 0.65 mm pitch) with all other RL78/G13 64-pin members including R5F100LLDFA#30 and R5F101LLAFA#30. Signal mapping, power pin locations, and reset behavior are fully consistent - enabling hardware reuse across flash/RAM variants without PCB changes.
