Product details
Overview
R5F101LEAFB#30 from Renesas is a 32-bit RL78/G13 microcontroller with no data flash memory, 128 KB code flash, 12 KB RAM, and 64-pin LFQFP (0.5 mm pitch) package. It operates from 1.6–5.5 V, achieves 41 DMIPS at 32 MHz, and delivers ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), targeting battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101LEAFB#30 datasheet, R5F101LEAFB#30 pinout, R5F101LEAFB#30 application, or R5F101LEAFB#30 equivalent, key selection criteria include its 64-pin LFQFP footprint, absence of on-chip data flash, 128 KB/12 KB memory partition, real-time clock with calendar support, and integrated 10-bit 26-channel ADC for embedded control loop sensing.
Technical Context
The R5F101LEAFB#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 subsystem clock). It integrates a 12-bit interval timer, one real-time clock with alarm/calendar, and watchdog timer powered by dedicated low-speed oscillator.
Peripheral integration includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timers, 2–4 DMA channels, and serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C (3–10 channels). Power management features HALT, STOP, and SNOOZE modes with on-chip POR and 14-level LVD.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101LEAFB#30?
The R5F101LEAFB#30 operates up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) at that frequency. This performance level supports real-time control tasks such as motor commutation, sensor fusion, and protocol stack handling while maintaining low power consumption. Its RL78 CPU core uses a 3-stage pipeline to achieve deterministic timing behavior critical for embedded control applications.
Does the R5F101LEAFB#30 include on-chip data flash memory?
No, the R5F101LEAFB#30 does not include on-chip data flash memory. It provides 128 KB of code flash only. The '101' in the part number explicitly indicates "data flash not provided", per Renesas' RL78/G13 part numbering convention. Applications requiring nonvolatile parameter storage must use external EEPROM or utilize code flash sectors with self-programming routines.
What package type and pin count does the R5F101LEAFB#30 use?
The R5F101LEAFB#30 uses a 64-pin LFQFP package with 0.5 mm pitch and 10 × 10 mm body size (RENESAS code PLQP0064KF-A). The '#FB' suffix denotes LFQFP, and the 'L' in the middle identifies the 64-pin variant. This package supports standard surface-mount assembly and provides robust thermal and mechanical performance for industrial environments.
What low-power modes are supported by the R5F101LEAFB#30, and what are their typical current draws?
The R5F101LEAFB#30 supports HALT mode (66 μA/MHz), STOP mode (0.57 μA), and SNOOZE mode. In STOP mode with only RTC and LVD active, it consumes just 0.57 μA - enabling multi-year battery operation in periodic wake-up applications. All modes retain RAM content and allow wake-up via external interrupt, RTC alarm, or LVD event.
Can the R5F101LEAFB#30 interface directly with 1.8 V or 2.5 V peripherals?
Yes, the R5F101LEAFB#30 supports different-potential interface operation, allowing its I/O ports to safely connect to 1.8 V, 2.5 V, or 3 V devices without level shifters. This capability is enabled by configurable input buffers and voltage-tolerant pins - verified for 6 V withstand voltage on select N-ch open-drain outputs - simplifying mixed-voltage system design.
