Product details
Overview
R5F100LDAFB#30 from Renesas is a 64-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LDAFB#30 datasheet, R5F100LDAFB#30 pinout, R5F100LDAFB#30 application, or R5F100LDAFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, -40°C to +85°C industrial temperature grade (D suffix), on-chip debug support, BGO-capable data flash, and hardware multiplier/divider for deterministic control-loop execution.
Technical Context
The R5F100LDAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-voltage domain I/O (up to 6 V tolerant on select pins), configurable N-ch open-drain outputs, and internal pull-up resistors for direct interfacing with 1.8/2.5/3.0 V peripherals.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one calendar RTC with alarm/correction, one watchdog timer, two to four UART/LIN channels, three to ten I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) channels - all accessible via memory-mapped SFRs with DMA support (4-channel controller).

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LDAFB#30?
The R5F100LDAFB#30 operates at up to 32 MHz using the high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation.
Does the R5F100LDAFB#30 support background data flash rewriting while executing code from main flash memory?
Yes, the R5F100LDAFB#30 supports background operation (BGO) for data flash, allowing the CPU to execute instructions from program memory during data flash erase/write sequences. This enables uninterrupted real-time operation in applications requiring frequent parameter updates without service interruption.
What is the analog input capability of the R5F100LDAFB#30, including reference and channel count?
The R5F100LDAFB#30 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports internal 1.45 V reference voltage and includes dedicated AVREFP/AVREFM pins (P20/P21) for external reference configuration, with temperature sensor functionality available in HS mode.
How does the R5F100LDAFB#30 manage ultra-low-power operation in STOP mode?
The R5F100LDAFB#30 achieves 0.57 μA typical current consumption in STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active. This enables decade-scale battery life in maintenance-free sensor nodes while preserving calendar time and voltage-monitoring capability.
Is the R5F100LDAFB#30 pin-compatible with other RL78/G13 variants in the same 64-pin LFQFP package?
Yes, the R5F100LDAFB#30 shares identical pinout and electrical characteristics with all other RL78/G13 devices in the 64-pin LFQFP-0.5mm package (e.g., R5F100LCAFB#30, R5F100LEAFB#30), enabling hardware reuse across memory-variant designs without PCB changes.
