Product details
Overview
R5F101SJAFB#10 from Renesas is a 128-pin, LFQFP-0.5 mm pitch, ultra-low-power 16-bit RL78/G13 microcontroller with 192 KB flash memory, 8 KB data flash, 16 KB RAM, and operation from 1.6 V to 5.5 V. It integrates a real-time clock, 10-bit A/D converter (26 channels), UART/LIN, I²C, CSI, 16-bit timers, and operates at up to 32 MHz for embedded control in battery-powered industrial sensors and smart meters.
For engineers reviewing the R5F101SJAFB#10 datasheet, R5F101SJAFB#10 pinout, R5F101SJAFB#10 application, or R5F101SJAFB#10 equivalent, key selection criteria include its 128-pin LFQFP package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for SNOOZE mode with background data flash rewriting.
Technical Context
The R5F101SJAFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz RTC mode). It supports multiple low-power modes-HALT, STOP, and SNOOZE-with 66 μA/MHz active current and 0.57 μA RTC+LVD standby consumption.
It features dual serial interfaces per channel (UART/LIN + CSI + I²C), 16-bit timer array (16 channels), 12-bit interval timer, calendar-based RTC with alarm and correction, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor-all operating across the full 1.6–5.5 V supply range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101SLAFB#10 | Same 128-pin LFQFP package, identical 192 KB flash/16 KB RAM, but D-grade (-40°C to +85°C) and no data flash. | Functionally identical; differs only in ordering suffix-no functional or electrical distinction from R5F101SJAFB#10. | Select when standard industrial temperature qualification and pin compatibility are required without data flash dependency. |
| R5F100SJAFB#10 | Same package and pinout, but includes 8 KB on-chip data flash and higher power consumption in STOP mode (1.25 μA vs. 0.57 μA). | Preferred where frequent nonvolatile parameter writes (e.g., calibration data, event logs) are needed without external memory. | Choose only if data flash is mandatory; otherwise R5F101SJAFB#10 offers superior ultra-low-power standby for battery-critical designs. |
Compared with R5F101SLAFB#10, R5F101SJAFB#10 is functionally identical; compared with R5F100SJAFB#10, it trades integrated data flash for lower standby current-making it optimal for long-life, write-light applications like remote sensors and utility meters.

FAQ
What is the maximum operating frequency and core performance of the R5F101SJAFB#10?
The R5F101SJAFB#10 operates at up to 32 MHz using its RL78 16-bit CISC core, delivering 41 DMIPS of processing performance. Its 3-stage pipeline and variable instruction timing-from 0.03125 μs at full speed to 30.5 μs in ultra-low-speed RTC mode-enable both high-throughput control and precision timing functions within the same R5F101SJAFB#10 device.
Does the R5F101SJAFB#10 include on-chip data flash memory?
No, the R5F101SJAFB#10 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number (per Renesas RL78/G13 documentation), this variant provides 192 KB of code flash only. Nonvolatile parameter storage requires external EEPROM, FRAM, or use of reserved code flash sectors-unlike the R5F100x series which integrates 4–8 KB of dedicated data flash.
What low-power modes are supported by the R5F101SJAFB#10, and what is its lowest standby current?
The R5F101SJAFB#10 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at 25°C-enabling decade-long operation on primary lithium batteries. The SNOOZE mode allows selected peripherals (e.g., ADC, UART) to operate while CPU remains halted, reducing average system power in duty-cycled applications.
Which communication interfaces are integrated into the R5F101SJAFB#10?
The R5F101SJAFB#10 integrates UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (Simplified SPI, up to 8 channels). All interfaces support multi-master and interrupt-driven operation. LIN support is implemented via UART peripheral with automatic sync-break detection and checksum generation-eliminating need for external LIN transceivers in body electronics applications.
What is the analog capability of the R5F101SJAFB#10, and does it include a temperature sensor?
The R5F101SJAFB#10 features an 8/10-bit successive-approximation A/D converter with up to 26 input channels, internal 1.45 V reference voltage, and an integrated temperature sensor. The sensor is accessible via dedicated ANI channel and calibrated across the -40°C to +85°C range, enabling board-level thermal monitoring without external components-directly usable by firmware running on the R5F101SJAFB#10.
