Product details
Overview
R5F101LEAFB#10 from Renesas is a 64-pin LFQFP (0.5 mm pitch), 32-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at 32 MHz with 41 DMIPS performance and ultra-low-power modes (0.57 μA RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces requiring precise timing, analog sensing, and secure firmware updates.
For engineers reviewing the R5F101LEAFB#10 datasheet, R5F101LEAFB#10 pinout, R5F101LEAFB#10 application, or R5F101LEAFB#10 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and integrated 10-bit 26-channel ADC with internal temperature sensor.
Technical Context
The R5F101LEAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It supports multiple low-power states-HALT, STOP, and SNOOZE-with dedicated low-speed oscillator for RTC and LVD operation.
It integrates dual serial interfaces (UART/LIN + CSI/SPI + I²C), up to 16× 16-bit timers including real-time clock with calendar/alarm, and DMA controller with 4 channels supporting background data flash rewriting. The device lacks on-chip data flash memory (per R5F101x naming convention), relying on external storage or code flash for nonvolatile data.

FAQ
What is the flash memory configuration of the R5F101LEAFB#10?
The R5F101LEAFB#10 contains 128 KB of on-chip code flash memory organized in 1 KB blocks, with no integrated data flash (per R5F101x series designation). It supports self-programming with boot swap and flash shield window functions, enabling secure firmware updates and field reconfiguration without external memory.
Does the R5F101LEAFB#10 support real-time clock functionality?
Yes, the R5F101LEAFB#10 includes a dedicated real-time clock (RTC) module with calendar support for 99 years, alarm interrupt, and automatic clock correction. It operates independently in STOP mode using the 32.768 kHz subsystem clock, maintaining accurate timekeeping while consuming only 0.57 μA.
What are the low-power operating modes supported by the R5F101LEAFB#10?
The R5F101LEAFB#10 supports HALT (66 μA/MHz), STOP (0.57 μA with RTC+LVD active), and SNOOZE modes. STOP mode retains RAM and register contents while disabling CPU and most peripherals-ideal for battery-backed applications requiring multi-year operation without recharge.
Can the R5F101LEAFB#10 interface with 1.8 V or 2.5 V peripherals?
Yes, the R5F101LEAFB#10 supports different-potential interface operation. Its I/O ports can be configured to connect directly to 1.8 V, 2.5 V, or 3.0 V devices without level shifters, thanks to independent input threshold control and selectable pull-up resistors-simplifying mixed-voltage system design.
