Product details
Overview
R5F100LEAFB#10 from Renesas is a 64-pin LFQFP (0.5 mm pitch), 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, 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 operation (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and on-chip RTC with calendar support.
For engineers reviewing the R5F100LEAFB#10 datasheet, R5F100LEAFB#10 pinout, R5F100LEAFB#10 application, or R5F100LEAFB#10 equivalent, key selection considerations include its 64-pin LFQFP-0.5mm package, industrial temperature rating, integrated data flash with background operation, low-power HALT/STOP/SNOOZE modes, and full peripheral set for sensor interface, motor control, and industrial HMI applications.
Technical Context
The R5F100LEAFB#10 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 uses a single 1.6–5.5 V supply and includes on-chip power-on-reset (POR) and voltage detector (LVD) with 14 selectable levels.
Its memory subsystem comprises 128 KB code flash (1 KB block size, security lockable), 8 KB data flash (1M rewrite cycles, BGO-capable), and 12 KB SRAM. Peripheral integration includes up to 16 × 16-bit timers, real-time clock with alarm/calendar, 10-bit ADC with internal reference and temperature sensor, and 3–10 I²C channels depending on variant configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LEAFB#10 | No data flash (0 KB); same core, peripherals, and package; lower memory cost. | Not suitable for firmware update storage or persistent data logging; ideal for fixed-function control where flash reprogramming is unnecessary. | Select when data retention between power cycles is not required and BOM cost optimization is critical. |
| R5F100LGAFB#10 | Same package and temperature grade, but 96 KB flash + 8 KB data flash + 8 KB RAM; lower memory capacity. | Reduced code space limits complex protocol stacks or GUI frameworks; adequate for simpler HMI or sensor concentrator roles. | Choose for cost-sensitive designs with moderate firmware footprint and no need for large buffer or algorithm memory. |
Compared with R5F100LEAFB#10, R5F101LEAFB#10 removes data flash to cut cost and simplify programming, while R5F100LGAFB#10 trades 32 KB flash and 4 KB RAM for lower unit price-both retain identical pinout, peripherals, and low-power behavior for drop-in layout reuse.
