Product details
Overview
R5F101LFAFB#30 from Renesas is a 64-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 128 KB flash, 12 KB RAM, and no data flash memory, operating from 1.6–5.5 V at -40°C to +85°C (industrial grade D). It delivers 41 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/I²C/CSI interfaces, and real-time clock for embedded control in metering and industrial HMI.
For engineers reviewing the R5F101LFAFB#30 datasheet, R5F101LFAFB#30 pinout, R5F101LFAFB#30 application, or R5F101LFAFB#30 equivalent, key selection criteria include its 64-pin LFQFP package, absence of data flash, industrial temperature rating, integrated RTC with calendar/alarm, and support for background data flash programming on compatible variants - though R5F101LFAFB#30 itself omits data flash.
Technical Context
The R5F101LFAFB#30 implements the RL78 CPU core with 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 on-chip resources including 128 KB code flash, 12 KB RAM, and hardware peripherals such as DMA (4 channels), multiplier/divider/MAC, and watchdog timer.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, enabling robust reset and brown-out handling. Clock sources comprise a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and dedicated low-speed oscillator for RTC/watchdog operation, ensuring timing integrity across supply and temperature variations.

FAQ
What is the maximum operating frequency and performance of the R5F101LFAFB#30?
The R5F101LFAFB#30 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction execution times - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed 32.768 kHz mode - enabling flexible trade-offs between throughput and power consumption in the R5F101LFAFB#30.
Does the R5F101LFAFB#30 include data flash memory?
No, the R5F101LFAFB#30 does not include data flash memory. As indicated by the "101" in its part number per Renesas' naming convention, it provides 128 KB of code flash and 12 KB of RAM but omits the 4–8 KB data flash found in "100" series variants like R5F100LFAFB#30. This simplifies flash management and reduces cost where persistent parameter storage is handled externally or via code flash emulation.
What package type and pin count does the R5F101LFAFB#30 use?
The R5F101LFAFB#30 uses a 64-pin LFQFP package with 0.5 mm pitch and 10 mm × 10 mm body size (RENESAS code PLQP0064KF-A). The "FB" suffix in the part number explicitly denotes this LFQFP-0.5mm variant, distinguishing it from LQFP-0.65mm ("FA") and other packages - ensuring correct PCB footprint selection for the R5F101LFAFB#30.
What is the operating temperature range for the R5F101LFAFB#30?
The R5F101LFAFB#30 is rated for industrial operation from -40°C to +85°C, denoted by the "D" grade in its full ordering code. This qualification meets extended temperature requirements for deployment in factory automation, building controls, and outdoor metering equipment - unlike consumer-grade "A" variants limited to -40°C to +85°C without industrial process validation.
Which communication interfaces are integrated into the R5F101LFAFB#30?
The R5F101LFAFB#30 integrates multiple serial interfaces: up to 10 channels of I²C/Simplified I²C, 2–4 channels of UART/LIN-capable serial, and 2–8 channels of CSI (Renesas' SPI-compatible interface). These support common industrial protocols including Modbus RTU (UART), sensor communication (I²C), and display/backlight control (CSI), all natively supported in the R5F101LFAFB#30 without external transceivers.
