Product details
Overview
R5F101GEANA#U0 from Renesas is a 16-bit RL78/G13 microcontroller with 64 KB flash memory, 4 KB data flash, and 4 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 10-bit ADC (26 channels), and integrated real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GEANA#U0 datasheet, R5F101GEANA#U0 pinout, R5F101GEANA#U0 application, or R5F101GEANA#U0 equivalent, key selection criteria include its HWQFN-40 package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D-grade), and support for SNOOZE mode low-power operation with UART/LIN, I²C, and CSI interfaces.
Technical Context
The R5F101GEANA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz) and 1 MB address space. It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), 16-bit timer array (12 channels), and background data flash rewrite capability via BGO.
Its power management includes HALT, STOP, and SNOOZE modes with on-chip POR and LVD (14-level detection), while peripheral integration covers DMA (2-channel), 16×16/32÷32 multiplier/divider, and hardware CRC calculation - all optimized for deterministic real-time control in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GEANA#U0 | Includes 4 KB on-chip data flash; identical pinout, package, and peripheral set | Preferred where field-updatable calibration tables or secure key storage is required | Select when persistent non-volatile data storage beyond code flash is mandatory |

FAQ
What is the operating temperature range for the R5F101GEANA#U0?
The R5F101GEANA#U0 is rated for industrial operation from –40°C to +85°C (D-grade). This specification is confirmed in the RL78/G13 datasheet Section 1.1 under "Operating ambient temperature", and applies to all R5F101x variants in the NA (HWQFN) package. The device does not support the extended +105°C G-grade variant.
Does the R5F101GEANA#U0 include on-chip data flash memory?
No, the R5F101GEANA#U0 does not include on-chip data flash memory. As defined in the RL78/G13 part numbering scheme (Section 1.2), the "101" prefix explicitly indicates "data flash not provided". This distinguishes it from R5F100x parts, which include 4–8 KB of dedicated data flash. Code flash remains 64 KB.
Which package type and pin count does the R5F101GEANA#U0 use?
The R5F101GEANA#U0 uses a 40-pin HWQFN package (6 × 6 mm, 0.5 mm pitch) with wettable flanks, identified by the "NA" suffix and "#U0" tray packaging code. This matches the PWQN0040KC-A Renesas package code specified in Table 1-1 (Page 6) of the datasheet.
Can the R5F101GEANA#U0 operate from a single 1.8 V supply?
Yes, the R5F101GEANA#U0 supports single-supply operation from 1.6 V to 5.5 V. At 1.8 V, it delivers full functionality including 10-bit ADC (with internal 1.45 V reference), RTC, and all communication peripherals - verified in the Electrical Characteristics table (Section 2.2) of the datasheet, where VDD min = 1.6 V across all operating modes.
What debug interface does the R5F101GEANA#U0 support?
The R5F101GEANA#U0 supports on-chip debug via the single-wire debug (SWD) interface using the TOOLRxD/TOOLTxD pins (P11/P12), compatible with Renesas E2 emulator and standard JTAG/SWD debuggers. This is documented in Section 1.1 ("On-chip debug function") and Pin Configuration diagrams (Page 13+), with no external debug header required.
