Product details
Overview
R5F101GJDNA#U0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for industrial control, sensor nodes, and battery-powered HMI applications.
For engineers reviewing the R5F101GJDNA#U0 datasheet, R5F101GJDNA#U0 pinout, R5F101GJDNA#U0 application, or R5F101GJDNA#U0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +105°C industrial temperature grade (G suffix), and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and DMA.
Technical Context
The R5F101GJDNA#U0 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). It integrates a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable), power management with HALT/STOP/SNOOZE modes, and on-chip LVD with 14 interrupt/reset levels.
Peripherals include up to 16 × 16-bit timers, 1 × 12-bit interval timer, 1 × calendar RTC with alarm/correction, 1 × watchdog timer, 10-bit A/D converter with 26 analog inputs and internal 1.45 V reference, and serial interfaces: 2–4 UART/LIN, 3–10 I²C/Simplified I²C, and 2–8 CSI (SPI-compatible) channels - all confirmed for the R5F101GJ variant in 48-pin packages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GJDNA#U0 | Includes 8 KB on-chip data flash; otherwise identical pinout, peripherals, and code flash size | Suitable where background data logging or parameter storage without external EEPROM is required | Select R5F100GJDNA#U0 when non-volatile parameter retention during power loss is mandatory |
| R5F101GJDFB#V0 | Same core/peripherals but in 48-pin LFQFP (7 mm × 7 mm, 0.5 mm pitch) instead of HWQFN | Better suited for prototyping, manual soldering, or legacy PCB layouts with QFP footprints | Choose R5F101GJDFB#V0 when board assembly process favors QFP over QFN or thermal pad rework is constrained |
Compared with R5F101GJDNA#U0, the R5F100GJDNA#U0 adds data flash capability at identical power/performance, while R5F101GJDFB#V0 trades the HWQFN thermal and density advantage for QFP manufacturability - enabling trade-offs between embedded storage needs and assembly flexibility.

FAQ
What is the flash memory configuration of the R5F101GJDNA#U0?
The R5F101GJDNA#U0 contains 128 KB of on-chip code flash memory and no integrated data flash - consistent with the R5F101x series designation. Its 12 KB SRAM supports real-time stack and buffer operations. Code flash block size is 1 KB, with security features prohibiting unauthorized erase/write of protected blocks. The R5F101GJDNA#U0 relies on external non-volatile storage or code-flash emulation for parameter retention.
Does the R5F101GJDNA#U0 support hardware data flash functionality?
No, the R5F101GJDNA#U0 does not include on-chip data flash memory. The "101" in the part number explicitly denotes absence of data flash, unlike "100" variants (e.g., R5F100GJDNA#U0) which integrate 8 KB. Applications requiring persistent data storage must use external EEPROM, FRAM, or implement data flash emulation in code flash - with associated wear-leveling and erase-cycle management handled in firmware.
What is the operating temperature range certified for the R5F101GJDNA#U0?
The R5F101GJDNA#U0 is rated for industrial operation from -40°C to +105°C, indicated by the "G" suffix in the part number. This extends beyond consumer-grade (-40°C to +85°C) and standard industrial (-40°C to +85°C, "D" suffix) variants, making it suitable for under-hood automotive modules, factory-floor controllers, and outdoor infrastructure equipment exposed to elevated ambient temperatures.
Which package type and footprint does the R5F101GJDNA#U0 use?
The R5F101GJDNA#U0 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with an exposed thermal pad, identified by the "NA" suffix and "#U0" tray packaging code. This package provides superior thermal dissipation and board space efficiency compared to QFP alternatives, and requires PCB layout adherence to Renesas' recommended land pattern (PWQN0048KB-A) and stencil design for reliable reflow soldering of the thermal pad.
Can the R5F101GJDNA#U0 operate without an external crystal oscillator?
Yes, the R5F101GJDNA#U0 operates fully from its on-chip high-speed oscillator, selectable from 1–32 MHz with ±1.0% accuracy across -20°C to +85°C. External crystals are optional and used only when higher frequency stability (e.g., <±100 ppm) or precise timing synchronization (e.g., USB, audio clocks) is required - eliminating BOM cost and board area for most industrial control and sensor applications.
