Product details
Overview
R5F101JFAFA#30 from Renesas is a 52-pin LQFP-0.65mm ultra-low-power 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, features an integrated 10-bit ADC (26 channels), RTC, and real-time clock correction, and targets battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101JFAFA#30 datasheet, R5F101JFAFA#30 pinout, R5F101JFAFA#30 application, or R5F101JFAFA#30 equivalent, key selection criteria include its 52-pin LQFP package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), and support for SNOOZE mode operation with RTC+LVD active at 0.57 μA.
Technical Context
The R5F101JFAFA#30 implements the RL78 CPU core with a 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 integrates a 16-bit timer array (16 channels), 12-bit interval timer, watchdog timer, and background operation-capable peripherals including UART/LIN, I²C, and CSI serial interfaces.
Power management includes HALT, STOP, and SNOOZE modes, with dedicated low-speed on-chip oscillator for watchdog and RTC operation. The device supports self-programming of code flash with boot swap and flash shield window functions, but excludes on-chip data flash memory - distinguishing it from R5F100x variants.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101JFAFA#30?
The R5F101JFAFA#30 operates up to 32 MHz, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 μs in high-speed mode using the on-chip oscillator, and supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation.
Does the R5F101JFAFA#30 include on-chip data flash memory?
No, the R5F101JFAFA#30 does not include on-chip data flash memory. This distinguishes it from R5F100x variants (e.g., R5F100JFAFA#30), which integrate 4 KB of data flash with background operation and 1 million write cycles. Firmware must store non-volatile parameters externally or in reserved code flash sectors.
What power-saving modes are supported by the R5F101JFAFA#30, and what is the lowest achievable current draw?
The R5F101JFAFA#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - enabling multi-year battery operation in sensor and metering applications. Active-mode current is 66 μA/MHz at 32 MHz.
Which serial communication interfaces are available on the R5F101JFAFA#30?
The R5F101JFAFA#30 integrates up to 4 UART/LIN channels (with LIN bus support), up to 10 I²C/Simplified I²C channels, and up to 8 CSI (SPI-compatible) channels. All are configurable per pin, with shared functions like P11 supporting RxD0, SDA00, and TOOLRxD simultaneously.
What is the analog capability of the R5F101JFAFA#30, and does it include internal reference and temperature sensing?
The R5F101JFAFA#30 features a 10-bit ADC with up to 26 analog input channels, internal 1.45 V reference voltage (selectable as AVREFP/AVREFM), and an integrated temperature sensor. These functions are available only in HS (high-speed main) mode and support ratiometric measurements and on-chip thermal monitoring without external components.
