Product details
Overview
R5F101JDAFA#10 from Renesas is a 52-pin LQFP-0.65mm ultra-low-power 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB RAM, no data flash, and industrial-grade -40°C to +85°C operation. It integrates a 32 MHz RL78 CPU core (41 DMIPS), 10-bit 12-channel ADC, RTC with calendar, UART/SPI/I²C interfaces, and low-power STOP/HALT modes for embedded control in battery-powered and energy-sensitive systems.
For engineers reviewing the R5F101JDAFA#10 datasheet, R5F101JDAFA#10 pinout, R5F101JDAFA#10 application, or R5F101JDAFA#10 equivalent, key selection considerations include its 52-pin LQFP package, absence of on-chip data flash, industrial temperature rating, and support for background data flash programming via external memory mapping - critical for firmware updates in field-deployed devices.
Technical Context
The R5F101JDAFA#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It supports true low-power operation: 66 μA/MHz active current and 0.57 μA in RTC+LVD-only STOP mode.
It features 8× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar/alarm, 1× watchdog timer, and serial peripherals including up to 4 UART/LIN channels, 8 CSI (SPI-compatible) channels, and 10 I²C/Simplified I²C channels - all accessible within its 52-pin LQFP footprint.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101JDFAA#50 | Same 64 KB flash, 4 KB RAM, 52-pin LQFP, but with TSSOP-0.65mm packaging (PLQP0052JA-A vs PLQP0052JD-B) | Lower profile, finer pitch; suited for space-constrained designs where thermal mass and hand-solderability are secondary | Select when board assembly uses fine-pitch reflow and volume cost optimization outweighs serviceability needs |
| R5F100JDAFA#10 | Identical package and pinout, but includes 4 KB data flash and supports background rewriting (BGO) | Required for applications needing nonvolatile parameter storage with runtime updates (e.g., calibration tables, configuration profiles) | Choose when field-updatable data persistence is mandatory; accept ~10% higher unit cost and identical power/performance envelope |
Compared with R5F101JDAFA#10, R5F101JDFAA#50 offers identical functionality in a different physical form factor, while R5F100JDAFA#10 adds data flash capability at the cost of increased die size and marginally higher active current - making the former ideal for compact layouts and the latter essential for self-configuring systems.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F101JDAFA#10?
The R5F101JDAFA#10 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This is measured under standard conditions (VDD = 1.8–5.5 V, TA = –40 to +85°C) and reflects the RL78 CPU core's 3-stage pipeline efficiency - sufficient for real-time motor control, sensor fusion, and protocol stack execution without external acceleration.
Does the R5F101JDAFA#10 include on-chip data flash memory?
No, the R5F101JDAFA#10 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number (per Renesas RL78/G13 documentation), it belongs to the data-flash-less variant series. Applications requiring nonvolatile parameter storage must use external EEPROM or leverage code flash sectors with wear-leveling software - unlike the R5F100x series which integrates 4–8 KB of dedicated data flash.
What low-power modes are supported by the R5F101JDAFA#10, and what is the lowest achievable current draw?
The R5F101JDAFA#10 supports HALT, STOP, and SNOOZE modes. Its lowest operational current is 0.57 μA in STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active - verified across the full industrial temperature range (–40°C to +85°C). This enables decade-scale battery life in always-on monitoring applications when paired with appropriate power gating and wake-on-event configuration.
Which communication interfaces are available on the R5F101JDAFA#10, and how many instances of each?
The R5F101JDAFA#10 provides UART/LIN (up to 4 channels), CSI (SPI-compatible serial interface, up to 8 channels), and I²C/Simplified I²C (up to 10 channels). All are implemented in hardware with independent baud rate generators and FIFO support. Pin multiplexing allows flexible allocation across the 52-pin LQFP package - for example, P10/P11/P12 can be configured as CSI0 or UART0, while P30–P33 support I²C0–I²C3 depending on mode settings.
Is the R5F101JDAFA#10 pin-compatible with any other RL78/G13 variants?
Yes, the R5F101JDAFA#10 is pin-compatible with all other 52-pin LQFP-0.65mm RL78/G13 variants sharing the PLQP0052JA-A or PLQP0052JD-B package codes - including R5F100Jx and R5F101Jx parts. However, functional differences exist: R5F100Jx parts include data flash and may differ in peripheral enablement or reset behavior. Direct substitution requires validation of memory map, bootloader compatibility, and peripheral initialization sequences.
