Product details
Overview
R5F101EDANA#20 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 2 KB RAM, and industrial-grade -40°C to +85°C operation. It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit 16-channel ADC, RTC with calendar/alarm, and ultra-low-power STOP mode (0.57 μA). It targets battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F101EDANA#20 datasheet, R5F101EDANA#20 pinout, R5F101EDANA#20 application, or R5F101EDANA#20 equivalent, key selection criteria include its 40-pin HWQFN-0.5mm-pitch package, absence of on-chip data flash (R5F101x series), 16-channel analog input capability, and support for SNOOZE-mode serial communication wake-up.
Technical Context
The R5F101EDANA#20 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). Its memory subsystem includes 64 KB code flash with 1 KB block erase granularity and 2 KB on-chip RAM mapped across four register banks.
Peripheral integration centers on low-power operation: HALT/STOP/SNOOZE modes, 14-level LVD with interrupt/reset options, 2-channel DMA, and background data flash rewriting (BGO). Serial interfaces include up to 4 UART/LIN channels, 3–10 I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable for wake-up from low-power states.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100EDANA#20 | Includes 4 KB data flash; identical pinout, package, and peripheral set | Preferred where nonvolatile parameter storage (e.g., calibration data, device ID) is required on-chip | Select when eliminating external EEPROM reduces BOM cost and PCB area |
| RL78/G14 R5F104BAANA#20 | Same package but 128 KB flash, 12 KB RAM, enhanced ADC (12-bit, 26 ch), and USB interface | Required for applications needing USB device connectivity or higher computational headroom | Choose when future firmware expansion or host-side diagnostics via USB are mandatory |

FAQ
What is the operating temperature range for the R5F101EDANA#20?
The R5F101EDANA#20 is rated for industrial operation from −40°C to +85°C. This rating is confirmed by Renesas' datasheet Section 1.1 under "Operating ambient temperature" for "D: Industrial applications". The device uses standard silicon process and thermal design to maintain timing and analog accuracy across this full range without derating.
Does the R5F101EDANA#20 include on-chip data flash memory?
No, the R5F101EDANA#20 does not include on-chip data flash memory. As indicated in the RL78/G13 datasheet Section 1.2 ("List of Part Numbers"), the "101" prefix denotes variants without data flash. The R5F101EDANA#20 provides 64 KB code flash and 2 KB RAM only-external nonvolatile memory is required for parameter storage.
Which package type and pin count does the R5F101EDANA#20 use?
The R5F101EDANA#20 uses a 40-pin HWQFN package (6 × 6 mm, 0.5 mm pitch), as specified in Table 1-1 (page 6) of the RL78/G13 datasheet. The "NA" suffix in the part number explicitly maps to the HWQFN package per Figure 1-1, and the "#20" denotes embossed tape packaging.
Can the R5F101EDANA#20 operate from a 1.8 V supply?
Yes, the R5F101EDANA#20 supports operation from 1.6 V to 5.5 V, including 1.8 V. Section 1.1 confirms "VDD = single power supply voltage of 1.6 to 5.5 V", and the 10-bit ADC maintains full functionality down to 1.6 V with internal 1.45 V reference-making it suitable for single-cell Li-ion or 2×AA battery systems.
How many analog input channels does the R5F101EDANA#20 support?
The R5F101EDANA#20 supports 16 analog input channels (ANI0–ANI15), as documented in the "A/D converter" feature list (Section 1.1) and verified in the 40-pin pin configuration diagram (page 13). All 16 channels are accessible on dedicated pins in the HWQFN-40 package, with no multiplexing conflicts in default configuration.
