Product details
Overview
R5F101LDAFB#V0 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 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces for industrial control and sensor node applications.
For engineers reviewing the R5F101LDAFB#V0 datasheet, R5F101LDAFB#V0 pinout, R5F101LDAFB#V0 application, or R5F101LDAFB#V0 equivalent, key selection criteria include its 64-pin LFQFP package, absence of data flash, industrial-grade -40°C to +85°C operation (D-grade), 128 KB code flash capacity, and support for background data flash programming via external library - critical for firmware updates in field-deployed equipment.
Technical Context
The R5F101LDAFB#V0 implements the RL78 CPU core with a 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), and a 1 MB address space. It integrates on-chip peripherals including an 8-channel 16-bit timer, 12-bit interval timer, calendar-based RTC with alarm and correction, and watchdog timer with dedicated low-speed oscillator.
Its serial interface suite includes up to 8 CSI channels, 4 UART/LIN channels, and 10 I²C/Simplified I²C channels - configurable per pin function - while the 10-bit A/D converter supports up to 26 analog inputs with internal 1.45 V reference and temperature sensor (HS mode only). DMA controller provides 4 channels with 2-clock transfers between SFR and RAM.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101LDAFB#V0?
The R5F101LDAFB#V0 operates at up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy), delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 μs in this mode, enabling responsive real-time control in applications such as motor drive and sensor fusion. The core also supports ultra-low-speed operation down to 32.768 kHz for RTC and LVD-only functions.
Does the R5F101LDAFB#V0 include data flash memory?
No, the R5F101LDAFB#V0 does not include data flash memory - it contains 128 KB of code flash and 12 KB of RAM only. This distinguishes it from the R5F100xxx series (e.g., R5F100LDAFB#V0), which integrates 8 KB of data flash. For applications requiring nonvolatile parameter storage, external EEPROM or FRAM must be used with the R5F101LDAFB#V0.
What package type and pin count does the R5F101LDAFB#V0 use?
The R5F101LDAFB#V0 uses a 64-pin LFQFP package with 0.5 mm pitch (10 × 10 mm body), identified by the "FB" suffix in the part number and "#V0" tray packaging code. This package is RoHS-compliant and rated MSL 3, making it suitable for standard surface-mount assembly processes in industrial and consumer manufacturing environments.
What is the operating temperature range and grade designation for the R5F101LDAFB#V0?
The R5F101LDAFB#V0 is rated for industrial operation from -40°C to +85°C and carries the "D" grade designation (per Renesas' part numbering convention). This ensures guaranteed functionality and parametric performance across harsh factory-floor or outdoor deployment conditions, unlike "A"-grade consumer variants limited to 0°C to +70°C or "G"-grade extended industrial (-40°C to +105°C) versions.
Which serial communication interfaces are supported by the R5F101LDAFB#V0?
The R5F101LDAFB#V0 supports three primary serial interface types: Simplified SPI (CSI) with up to 8 channels, UART/LIN with up to 4 channels (including LIN bus compliance), and I²C/Simplified I²C with up to 10 channels. These are implemented via multiplexed pins (e.g., P10–P12 for CSI0/UART0/I²C0), allowing flexible allocation based on system requirements without additional hardware.
