Product details
Overview
R5F101JLAFA#30 from Renesas is a 52-pin LQFP-0.65mm ultra-low-power 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring integrated RTC, 10-bit ADC (26 channels), UART/LIN, I²C, and SPI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101JLAFA#30 datasheet, R5F101JLAFA#30 pinout, R5F101JLAFA#30 application, or R5F101JLAFA#30 equivalent, key selection criteria include its data flash absence (vs. R5F100x series), 52-pin LQFP-0.65mm package compatibility, -40°C to +85°C industrial temperature grade (D-grade), and real-time clock with calendar/alarm functionality for time-stamped telemetry.
Technical Context
The R5F101JLAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock), and includes on-chip debug, self-programming flash with boot swap, and background operation during data flash rewriting.
It integrates dual power management modes - HALT (66 μA/MHz active current) and STOP (0.57 μA with RTC+LVD active) - alongside a 14-level voltage detector, 2-channel DMA, 16×16/32÷32 hardware multiplier/divider, and peripheral-rich I/O including 26 analog inputs, 16-bit timers (12 channels), and simplified SPI/UART/I²C with LIN support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100JLAFA#30 | Same package and pinout, but includes 8 KB data flash (vs. 0 KB in R5F101JLAFA#30) | Required where field firmware updates or parameter storage exceed 4 KB SRAM capacity | Select when persistent non-volatile storage >4 KB is needed; otherwise R5F101JLAFA#30 reduces cost and flash overhead |
| RL78/G14 R5F104GJAFA#30 | Enhanced RL78/G14 variant with 128 KB flash, 12 KB RAM, and additional 12-bit ADC channels | Targeted at higher-fidelity sensor fusion or multi-protocol gateway designs requiring more memory and peripherals | Choose for scalability beyond 64 KB flash or when needing CAN interface (not present in G13 family) |
Compared with R5F100JLAFA#30, the R5F101JLAFA#30 trades data flash capacity for lower cost and reduced flash programming complexity; versus RL78/G14, it offers proven maturity and lower power in resource-constrained endpoints where CAN or extended memory is unnecessary.

FAQ
What is the maximum operating frequency and performance of the R5F101JLAFA#30?
The R5F101JLAFA#30 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline and high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and –40°C to +85°C. The R5F101JLAFA#30 maintains consistent timing even under voltage scaling due to adaptive clock control and built-in POR/LVD circuits.
Does the R5F101JLAFA#30 include data flash memory?
No, the R5F101JLAFA#30 does not include data flash memory. As indicated by the "101" prefix in its part number (per Renesas RL78/G13 documentation), it provides 64 KB of code flash and 4 KB of RAM but omits dedicated data flash - unlike "100"-series variants such as R5F100JLAFA#30 which include 8 KB data flash. This makes the R5F101JLAFA#30 suitable for applications relying on SRAM-based parameter storage or external EEPROM.
What package type and pin count does the R5F101JLAFA#30 use?
The R5F101JLAFA#30 uses a 52-pin LQFP package with 10 mm × 10 mm body size and 0.65 mm pin pitch (designated by "FA" in the suffix). It is RoHS-compliant and intended for surface-mount reflow assembly. This package matches pin-for-pin compatibility with other RL78/G13 52-pin variants like R5F100JLAFA#30, enabling design reuse across flash-configured derivatives.
What temperature grade is specified for the R5F101JLAFA#30?
The R5F101JLAFA#30 is rated for industrial operation from –40°C to +85°C (D-grade), as confirmed by its "D" position in the part number decoding per Renesas RL78/G13 datasheet Rev. 3.80. It does not support the extended –40°C to +105°C (G-grade) range. This makes the R5F101JLAFA#30 appropriate for enclosed industrial controls, building automation, and metering applications within standard ambient thermal envelopes.
Which communication interfaces are supported by the R5F101JLAFA#30?
The R5F101JLAFA#30 supports UART (with LIN bus compliance), I²C/Simplified I²C (3–10 channels), and CSI (SPI-compatible serial interface, 2–8 channels). It lacks CAN, USB, or Ethernet interfaces. All serial peripherals share flexible pin mapping and support multi-drop configurations, enabling robust sensor networking and host communication in compact embedded systems using the R5F101JLAFA#30.
