Product details
Overview
R5F101LFDFB#30 from Renesas is a 32-bit RL78/G13 microcontroller with 128 KB flash memory, 12 KB RAM, and no data flash, housed in a 64-pin LFQFP package (0.5 mm pitch). It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT, targeting battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F101LFDFB#30 datasheet, R5F101LFDFB#30 pinout, R5F101LFDFB#30 application, or R5F101LFDFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm footprint, absence of on-chip data flash, industrial-grade temperature range (−40°C to +85°C), integrated 10-bit ADC (26 channels), RTC with calendar, and dual UART/LIN support for embedded telemetry and motor control systems.
Technical Context
The R5F101LFDFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space, with 128 KB code flash organized in 1 KB blocks and security features including block erase prohibition.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, one real-time clock with alarm and calendar functions, one watchdog timer, two to four UART/LIN channels, three to ten I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) interfaces - all configurable via dedicated SFRs without external glue logic.

FAQ
Does R5F101LFDFB#30 include on-chip data flash memory?
No, R5F101LFDFB#30 does not include data flash memory. The "101" in the part number explicitly denotes absence of data flash, distinguishing it from "100" series variants like R5F100LFDFB#30 which integrate 8 KB data flash. Code flash remains fully functional for program storage and self-programming with boot swap capability.
What is the maximum operating frequency and corresponding performance of R5F101LFDFB#30?
R5F101LFDFB#30 operates up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This speed is achievable across the full 1.6–5.5 V supply range and −40°C to +85°C temperature range, making it suitable for deterministic real-time control tasks such as motor commutation and PID regulation.
Which communication interfaces are supported by R5F101LFDFB#30?
R5F101LFDFB#30 supports up to four UART/LIN channels, three to ten I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) interfaces. All are implemented in hardware with dedicated registers and interrupt vectors - no bit-banging required. LIN compliance is achieved through UART auto-synchronization and break detection features.
Is R5F101LFDFB#30 pin-compatible with other RL78/G13 64-pin variants?
Yes, R5F101LFDFB#30 shares identical 64-pin LFQFP mechanical footprint and pin assignment with all other RL78/G13 devices in the FB package variant (e.g., R5F100LFDFB#30, R5F101LGAFB#30). Signal mapping, power/ground pin locations, and reset behavior are consistent across this package group, enabling drop-in replacement within the same memory/peripheral configuration constraints.
What low-power modes are available on R5F101LFDFB#30 and their typical current consumption?
R5F101LFDFB#30 offers HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC and LVD active), and SNOOZE mode (low-power background operation with selected peripherals active). STOP mode current is measured at VDD = 3.0 V, TA = 25°C, with only RTC and LVD enabled - critical for long-duration battery operation in metering and remote sensing.
Does R5F101LFDFB#30 support hardware-accelerated cryptographic functions?
No, R5F101LFDFB#30 does not include dedicated cryptographic accelerators such as AES or SHA engines. Security relies on software-implemented algorithms and flash memory protection features (block erase prohibition, flash shield window). For hardware crypto requirements, consider Renesas RA-family MCUs or RL78/G23 with built-in TRNG and AES-128 acceleration.
