Product details
Overview
R5F101JEAFA#10 from Renesas is a 52-pin LQFP-0.65mm microcontroller in the RL78/G13 family, featuring 64 KB flash memory, 4 KB data flash, 4 KB RAM, 10-bit A/D converter with 26 input channels, and real-time clock with calendar function. It operates from 1.6 V to 5.5 V and supports ultra-low-power modes including STOP (0.57 μA) and HALT, targeting battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101JEAFA#10 datasheet, R5F101JEAFA#10 pinout, R5F101JEAFA#10 application, or R5F101JEAFA#10 equivalent, key selection criteria include its 52-pin LQFP package, absence of on-chip data flash (R5F101x series), integrated RTC with alarm/calendar, 10-bit ADC resolution across 26 analog inputs, and support for LIN-bus via UART peripherals.
Technical Context
The R5F101JEAFA#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 subsystem clock). It integrates dual UART modules supporting LIN-bus protocol, three I²C/Simplified I²C channels, and up to eight CSI (SPI-compatible) interfaces - all configurable without external transceivers.
Power management includes an on-chip voltage detector with 14 selectable LVD levels, POR circuit, and multiple low-power states (HALT, STOP, SNOOZE). The device uses a dedicated low-speed on-chip oscillator for watchdog timer operation and supports background operation during data flash rewriting via BGO functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 CISC CPU with 3-stage pipeline and 1 MB address space |
| Operating Voltage | 1.6 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, and 3.3 V peripherals |
| Flash Memory | 64 KB code flash - sufficient for complex sensor fusion firmware with bootloader and OTA update partitioning |
| Data Flash | None - R5F101x series excludes on-chip data flash; external EEPROM or FRAM required for nonvolatile parameter storage |
| A/D Converter | 10-bit resolution, 26-channel input - supports simultaneous sampling of multi-sensor analog signals in environmental monitoring |
| Real-Time Clock | Calendar function (99-year range), alarm, and clock correction - eliminates need for external RTC IC in time-stamped logging applications |
| Low-Power Modes | STOP mode draws 0.57 μA (RTC + LVD active); HALT mode draws 66 μA/MHz - extends battery life in intermittent wake-up systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100JEAFA#10 | Includes 4 KB on-chip data flash; otherwise identical flash/RAM/peripherals | Preferred where nonvolatile parameter storage (e.g., calibration data, configuration) must reside on-chip without external EEPROM | Select R5F100JEAFA#10 if data flash is required; R5F101JEAFA#10 reduces cost where external NV memory is acceptable |
| R5F101JEAFA#30 | Identical silicon; differs only in packaging (embossed tape vs. tray) | No functional difference; #30 used for automated SMT assembly, #10 for manual prototyping or low-volume production | Choose #30 for high-volume pick-and-place lines; #10 suits engineering validation and small-batch builds |
Compared with R5F100JEAFA#10, the R5F101JEAFA#10 saves BOM cost by omitting data flash but requires external NV storage; compared with R5F101JEAFA#30, the #10 variant offers tray packaging for easier handling during development and low-volume manufacturing.

Does the R5F101JEAFA#10 include on-chip data flash memory?
No, the R5F101JEAFA#10 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number per Renesas documentation, it belongs to the data-flash-free variant of the RL78/G13 family. Applications requiring nonvolatile parameter storage must use external EEPROM, FRAM, or serial flash alongside the R5F101JEAFA#10.
Which communication interfaces are supported by the R5F101JEAFA#10?
The R5F101JEAFA#10 supports up to two UART modules (with LIN-bus capability), three I²C/Simplified I²C channels, and up to eight CSI (SPI-compatible) interfaces. It also includes a 10-bit A/D converter with 26 analog inputs and a real-time clock with calendar and alarm functions - all usable concurrently without resource conflict.
What is the operating temperature range for the R5F101JEAFA#10?
The R5F101JEAFA#10 is rated for industrial operation from –40°C to +85°C ('D' grade). This is confirmed by its part number suffix 'FA', which maps to the D-field application classification in Renesas RL78/G13 documentation, making it suitable for factory automation, building controls, and outdoor metering equipment.
How many analog input channels does the R5F101JEAFA#10 support?
The R5F101JEAFA#10 supports 26 analog input channels for its 10-bit A/D converter, as specified in the RL78/G13 datasheet for 52-pin LQFP packages.
