Product details
Overview
R5F100GLANA#W0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed (41 DMIPS), and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, RTC, and operates from 1.6–5.5 V for battery-powered industrial sensors and smart meters.
For engineers reviewing the R5F100GLANA#W0 datasheet, R5F100GLANA#W0 pinout, R5F100GLANA#W0 application, or R5F100GLANA#W0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, industrial-grade -40°C to +105°C operation (G-grade), integrated data flash with 1M rewrite cycles, SNOOZE mode for low-latency wake-up, and hardware multiplier/divider for real-time control math.
Technical Context
The R5F100GLANA#W0 implements the RL78 CPU core with a 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). Its memory subsystem includes 128 KB on-chip code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB RAM - all accessible within a 1 MB address space.
Peripheral integration centers on mixed-signal timing and communication: one 12-bit interval timer, one calendar RTC with alarm/correction, eight 16-bit timers, up to ten I²C channels, four UART/LIN channels, and a 10-bit ADC with internal 1.45 V reference and temperature sensor - all configurable under single-supply 1.6–5.5 V operation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GLAFB#V0 | LQFP-48 (7×7 mm, 0.5 mm pitch) vs. HWQFN-48; identical memory, peripherals, and G-grade temp range. | Better suited for prototyping or manual soldering; larger footprint eases test probe access and thermal management. | Select when board assembly uses reflow-only processes or requires higher thermal dissipation than HWQFN allows. |
| R5F101GLANA#W0 | Same package and pinout but lacks data flash (0 KB); retains 128 KB code flash, 12 KB RAM, and identical peripherals. | Ideal for cost-sensitive applications where firmware updates occur only via external loader or where parameter storage uses external EEPROM. | Choose when data logging or field firmware patching is unnecessary - reduces BOM cost by eliminating data flash redundancy. |
Compared with R5F100GLAFB#V0, the R5F100GLANA#W0 offers superior board-area efficiency and thermal performance in space-constrained modules, while R5F101GLANA#W0 trades data flash capability for lower unit cost in static-function deployments.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100GLANA#W0?
The R5F100GLANA#W0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under typical conditions (VDD = 3.3 V, TA = 25°C). The R5F100GLANA#W0 achieves this while maintaining ultra-low active current (66 μA/MHz), making it suitable for high-throughput yet power-constrained applications like real-time sensor fusion.
Does the R5F100GLANA#W0 support in-system programming and secure firmware updates?
Yes, the R5F100GLANA#W0 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features for security. Its self-programming capability - including boot swap and background operation (BGO) for data flash - enables robust over-the-air (OTA) updates without interrupting application execution, a key requirement for deployed R5F100GLANA#W0-based edge devices.
What analog features are integrated into the R5F100GLANA#W0 for sensor interfacing?
The R5F100GLANA#W0 integrates a 10-bit ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-die temperature sensor. These features allow direct connection of resistive sensors, thermistors, and voltage-output transducers without external references or signal conditioning. The ADC operates across the full 1.6–5.5 V supply range, ensuring accuracy in varying battery conditions - a critical capability for R5F100GLANA#W0 implementations in portable instrumentation.
How does the SNOOZE mode in the R5F100GLANA#W0 improve responsiveness in low-power systems?
SNOOZE mode allows selected peripherals (UART, SPI, I²C) to remain active while the CPU is halted, enabling immediate wake-up upon frame reception or transmission completion - typically within <10 μs. This eliminates the latency of full CPU restart, making the R5F100GLANA#W0 ideal for always-listening interfaces like LIN slaves or BLE command responders, where deterministic response time is essential despite ultra-low average power draw.
Is the R5F100GLANA#W0 qualified for automotive applications, and what temperature grade does it carry?
Yes, the R5F100GLANA#W0 carries the 'G' suffix, indicating qualification for industrial applications over -40°C to +105°C ambient temperature - a range commonly required for under-hood and cabin-adjacent automotive modules such as door controllers, seat positioners, and HVAC actuators. While not AEC-Q100 certified out-of-box, its G-grade thermal specification and Renesas' automotive process heritage make the R5F100GLANA#W0 a proven foundation for automotive-qualified designs.
