Product details
Overview
R5F100GEANA#20 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 3 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and integrated real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100GEANA#20 datasheet, R5F100GEANA#20 pinout, R5F100GEANA#20 application, or R5F100GEANA#20 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, 64 KB code flash with self-programming and flash shield window, 10-bit ADC with internal temperature sensor, and support for LIN-bus UART and I²C interfaces in industrial-temperature (−40°C to +105°C) operation.
Technical Context
The R5F100GEANA#20 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 on-chip power-on-reset, 14-level voltage detector, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.
Its peripheral set includes up to 16 × 16-bit timers, one 12-bit interval timer, calendar-based real-time clock with alarm and correction, watchdog timer with dedicated low-speed oscillator, and serial interfaces: CSI (SPI-compatible), UART/LIN (2–4 channels), and I²C/Simplified I²C (3–10 channels).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GEAFB#V0 | Same core, memory, and peripherals; differs in 48-pin LFQFP (7×7 mm, 0.5 mm pitch) package | Preferred where through-hole or larger pitch layout is required; less suitable for ultra-dense PCBs | Select when mechanical mounting or legacy footprint compatibility outweighs size constraints |
| R5F101GEANA#20 | Identical package and pinout but lacks data flash (0 KB vs. 4 KB); same 64 KB code flash and 3 KB RAM | Used where firmware-only storage suffices and data logging is handled externally | Choose when eliminating data flash reduces cost and security requirements are minimal |
Compared with R5F100GEANA#20, R5F100GEAFB#V0 offers identical functionality in a larger, more manufacturable LFQFP package, while R5F101GEANA#20 removes data flash to lower unit cost - making the original optimal for compact, data-logging-enabled industrial edge nodes requiring secure in-field updates.

Does the R5F100GEANA#20 support in-system programming via standard interfaces?
Yes, the R5F100GEANA#20 supports in-system programming using the on-chip debug interface (OCDS) via SWD or FINE, enabling firmware updates and debugging without removing the device from the PCB - critical for field-deployed R5F100GEANA#20 units in remote sensor networks.
How many ADC channels does the R5F100GEANA#20 provide, and what is their resolution?
The R5F100GEANA#20 integrates a 10-bit successive approximation ADC with up to 26 analog input channels (ANI0–ANI25), including dedicated AVREFP/AVREFM pins and an internal temperature sensor - delivering consistent 10-bit linearity across its 1.6–5.5 V supply range for precision sensor interfacing.
What packaging format is used for the R5F100GEANA#20, and is it RoHS-compliant?
The R5F100GEANA#20 uses a 48-pin HWQFN package (7 × 7 mm, 0.5 mm pitch) with exposed thermal pad and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 - verified by Renesas' material declarations and certified by third-party lab testing.
Can the R5F100GEANA#20 operate from a single 1.8 V supply, and what features remain functional?
Yes, the R5F100GEANA#20 operates down to 1.6 V, so 1.8 V is fully supported. At 1.8 V, all core functions remain active including 32 MHz operation (with reduced max frequency margin), 10-bit ADC (with internal 1.45 V reference), RTC, and LIN-capable UART - enabling energy harvesting and coin-cell designs.
