Product details
Overview
R5F101LCAFA#10 from Renesas is a 64-pin LQFP-0.65mm, 16 KB flash, 2 KB RAM, data-flash-free RL78/G13 16-bit microcontroller operating at 1.6–5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), used in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101LCAFA#10 datasheet, R5F101LCAFA#10 pinout, R5F101LCAFA#10 application, or R5F101LCAFA#10 equivalent, key selection criteria include its 64-pin LQFP package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), integrated 10-bit ADC (26 channels), real-time clock with calendar/alarm, and hardware UART/I²C/CSI interfaces for sensor node communication and low-power control.
Technical Context
The R5F101LCAFA#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock), and features a 1 MB address space with four 8-bit register banks. It integrates a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable) and dedicated low-speed oscillator for watchdog timing.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one real-time clock with calendar and alarm, two to four UART/LIN channels, three to ten I²C/Simplified I²C channels, two to eight CSI (SPI-compatible) channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all optimized for deterministic real-time control in constrained power environments.

FAQ
What is the maximum operating frequency and core performance of the R5F101LCAFA#10?
The R5F101LCAFA#10 operates at up to 32 MHz with the RL78 CPU core, achieving 41 DMIPS. Its high-accuracy on-chip oscillator supports frequencies from 1 MHz to 32 MHz with ±1.0% tolerance across 1.8–5.5 V and -20°C to +85°C. The core's 3-stage pipeline and variable instruction timing (0.03125 μs to 30.5 μs) enable both high-speed computation and ultra-low-power sleep-state responsiveness in the R5F101LCAFA#10.
Does the R5F101LCAFA#10 include on-chip data flash memory?
No, the R5F101LCAFA#10 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number per Renesas RL78/G13 documentation, this variant provides 16 KB of code flash and 2 KB of RAM only. Data retention must be implemented using code flash wear-leveling or external serial EEPROM/NVSRAM. This distinguishes the R5F101LCAFA#10 from the "100" series (e.g., R5F100LCAFA#10), which includes 4 KB data flash.
What is the operating temperature range and industrial qualification status of the R5F101LCAFA#10?
The R5F101LCAFA#10 is rated for -40°C to +85°C ambient operation and belongs to the "D" industrial grade per Renesas' part numbering scheme. It is fully qualified for industrial applications, including extended thermal cycling, humidity exposure, and ESD robustness per AEC-Q100 stress test guidelines. This makes the R5F101LCAFA#10 suitable for deployment in factory automation, building controls, and outdoor metering where environmental resilience is required.
Which serial communication interfaces are supported by the R5F101LCAFA#10?
The R5F101LCAFA#10 supports up to four UART/LIN channels, up to ten I²C/Simplified I²C channels, and up to eight CSI (SPI-compatible) channels - all configurable via shared pins. Hardware flow control, LIN bus compliance (including auto-sync and checksum), and multimaster I²C arbitration are natively supported. These interfaces enable simultaneous connectivity to displays, sensors, transceivers, and host processors without software bit-banging, directly within the R5F101LCAFA#10's peripheral set.
How does the R5F101LCAFA#10 manage ultra-low-power operation in battery-powered systems?
The R5F101LCAFA#10 achieves ultra-low-power operation through multiple dedicated modes: HALT (1.23 μA typical), STOP (0.57 μA with RTC + LVD active), and SNOOZE (low-latency wake from UART/I²C). Its 66 μA/MHz active current, combined with sub-μA retention in STOP mode and fast wake-up (<;3.8 μs from HALT), enables multi-year battery life in sensor nodes. The R5F101LCAFA#10 also integrates a precision 32.768 kHz subsystem clock and programmable voltage detector to minimize external component count while maintaining system reliability.
