Product details
Overview
R5F100GLANA#20 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and industrial-grade -40°C to +105°C operation. It integrates 16-bit timers (12 channels), 10-bit ADC (24 channels), RTC, UART/I²C/CSI interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for battery-powered sensor nodes and motor control.
For engineers reviewing the R5F100GLANA#20 datasheet, R5F100GLANA#20 pinout, R5F100GLANA#20 application, or R5F100GLANA#20 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm pitch package, 128 KB code flash with self-programming, 10-bit ADC resolution across 24 analog inputs, and support for SNOOZE mode DMA-triggered background data flash writes without CPU intervention.
Technical Context
The R5F100GLANA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz). It supports dual-clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and subsystem clock (32.768 kHz).
Its peripheral set includes 12× 16-bit timers with capture/compare, 1× real-time clock with calendar/alarm, 2× UART (LIN-capable), 3× I²C, 2× CSI, 10-bit ADC with internal 1.45 V reference and temperature sensor, and 4-channel DMA supporting transfers between SFRs and RAM in just 2 clocks per 8/16-bit word.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GLAFB#V0 | Same core, memory, and peripherals; differs in package (48-pin LFQFP, 0.5 mm pitch) and packaging (#V0 tray vs #20 embossed tape) | Preferred for through-hole prototyping or manual assembly due to larger pitch and exposed leads | Select when PCB layout requires easier solder inspection or rework; no functional change required |
| R5F101GLANA#20 | Omits 8 KB data flash; retains identical code flash (128 KB), RAM (12 KB), peripherals, and package | Suitable where persistent parameter storage is handled externally or not required | Choose to reduce BOM cost when background data flash writes are unnecessary |
Compared with R5F100GLANA#20, R5F100GLAFB#V0 offers identical functionality in a more serviceable package but occupies larger board area, while R5F101GLANA#20 removes data flash to lower cost-making it viable only when non-volatile parameter storage is implemented elsewhere.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GLANA#20?
The R5F100GLANA#20 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 core achieves this with a 3-stage pipeline and minimum instruction execution time of 0.03125 μs. This enables deterministic real-time control in applications such as motor commutation and sensor fusion where cycle count predictability matters.
Does the R5F100GLANA#20 support in-system programming and secure firmware updates?
Yes, the R5F100GLANA#20 supports full in-system programming via its on-chip debug interface and includes robust security features: flash block erase/write prohibition, boot swap functionality, and flash shield window protection. These capabilities allow safe field firmware updates while preventing unauthorized access or corruption - essential for deployed industrial and medical devices.
How many analog input channels does the R5F100GLANA#20 support, and what is the ADC resolution?
The R5F100GLANA#20 integrates a 10-bit successive approximation register (SAR) ADC with up to 24 analog input channels (ANI0–ANI23). It includes an internal 1.45 V reference and supports differential input modes. The ADC operates across the full 1.6–5.5 V VDD range, enabling accurate measurements in both low-voltage battery systems and higher-voltage industrial sensors.
What low-power modes are available on the R5F100GLANA#20, and what is the lowest current consumption?
The R5F100GLANA#20 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes just 0.57 μA - verified at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year battery life in wireless sensor nodes and other energy-constrained applications without sacrificing timekeeping or fault detection.
Is the R5F100GLANA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin HWQFN package - including R5F100GLANA#20, R5F100GKANA#20, and R5F101GLANA#20 - share identical pinouts and electrical characteristics. This allows hardware reuse across memory variants (e.g., 128 KB vs 96 KB flash) and feature sets (e.g., with or without data flash), simplifying design scalability and inventory management.
