Product details
Overview
R5F101LCAFB#10 from Renesas is a 64-pin, LFQFP-0.5 mm pitch, 16 KB flash, no data flash, industrial-grade (−40°C to +85°C) RL78/G13 16-bit microcontroller featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), 32 MHz max CPU speed, and integrated 10-bit ADC with 26 channels. It targets battery-powered sensor nodes and industrial control interfaces requiring deterministic real-time response and long-term reliability.
For engineers reviewing the R5F101LCAFB#10 datasheet, R5F101LCAFB#10 pinout, R5F101LCAFB#10 application, or R5F101LCAFB#10 equivalent, key selection criteria include its 16 KB code flash without data flash, 64-pin LFQFP package, −40°C to +85°C industrial temperature rating, absence of on-chip data flash memory, and compatibility with RL78/G13 development tools and firmware libraries.
Technical Context
The R5F101LCAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports HALT, STOP, and SNOOZE low-power modes and integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer with 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 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all operating across 1.6–5.5 V supply range with ±1.0% high-speed on-chip oscillator accuracy.
Key Specifications

FAQ
What is the flash memory configuration of the R5F101LCAFB#10?
The R5F101LCAFB#10 contains 16 KB of on-chip code flash memory and no data flash memory, as indicated by the "101" prefix in the part number per Renesas RL78/G13 naming convention. This configuration supports firmware-only storage with external non-volatile memory required for parameter logging or field updates.
Does the R5F101LCAFB#10 support hardware debugging?
Yes, the R5F101LCAFB#10 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. Debug access uses the dedicated TOOLRxD pin (P11) and supports breakpoints, watchpoints, and real-time variable inspection without requiring additional debug headers or SWD/JTAG adapters.
What is the maximum ADC sampling rate achievable with the R5F101LCAFB#10?
The R5F101LCAFB#10 supports up to 10-bit ADC conversion in approximately 1.2 μs per channel under optimal conditions (VDD ≥ 2.7 V, internal clock source), enabling sustained sampling rates exceeding 800 kSPS across multiple channels using hardware triggers and DMA transfer to avoid CPU overhead.
Can the R5F101LCAFB#10 operate from a single 1.8 V supply?
Yes, the R5F101LCAFB#10 operates across 1.6 V to 5.5 V, so it functions reliably at 1.8 V. However, maximum CPU frequency is reduced to 16 MHz at 1.8 V per the datasheet's voltage-frequency specification, and certain peripherals like the high-speed oscillator may require higher VDD for full accuracy.
Is the R5F101LCAFB#10 pin-compatible with other RL78/G13 64-pin variants?
Yes, the R5F101LCAFB#10 shares identical 64-pin LFQFP mechanical dimensions and pinout with all other RL78/G13 devices in the same package variant (e.g., R5F100LCAFB#10, R5F101LCDFB#10), enabling drop-in replacement where flash size, data flash presence, and temperature grade align with system requirements.
