Product details
Overview
R5F101GLANA#U0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 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 for industrial sensor and control applications.
For engineers reviewing the R5F101GLANA#U0 datasheet, R5F101GLANA#U0 pinout, R5F101GLANA#U0 application, or R5F101GLANA#U0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +105°C industrial temperature grade (G suffix), and support for SNOOZE mode, BGO data flash rewriting, and LIN-capable UARTs.
Technical Context
The R5F101GLANA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed main system clock and independent low-speed subsystem clock for RTC and watchdog operation.
Its peripheral set includes 8-channel 16-bit timers, 1-channel 12-bit interval timer, calendar-based RTC with alarm and correction, 2–4 channel DMA, and serial interfaces comprising CSI (SPI-compatible), UART/LIN, and I²C - all configurable via dedicated SFRs and interrupt vectors mapped to the 1 MB address space.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GLANA#U0 | Includes 8 KB data flash; identical pinout, package, and peripheral set. | Required where field-updatable calibration tables or logging data must be stored on-chip. | Select when non-volatile parameter storage is needed without external EEPROM or flash. |
| R5F101GLAFA#V0 | LQFP-48 (7×7 mm, 0.5 mm pitch) instead of HWQFN; same memory and peripheral configuration. | Preferred for manual assembly, prototyping, or thermal environments where QFP's exposed pad is not required. | Choose for easier rework, legacy PCB compatibility, or when thermal dissipation via top-side convection suffices. |
Compared with R5F101GLANA#U0, R5F100GLANA#U0 adds on-chip data flash for persistent parameter storage but increases cost and complexity, while R5F101GLAFA#V0 trades HWQFN's thermal and density advantages for LQFP's assembly flexibility - both retain identical instruction set, clocking, and peripheral register mapping.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101GLANA#U0?
The R5F101GLANA#U0 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 standard test conditions (VDD = 3.3 V, TA = 25°C). The R5F101GLANA#U0 achieves this without requiring external acceleration blocks, making it suitable for real-time control tasks such as brushless DC motor commutation or protocol parsing.
Does the R5F101GLANA#U0 include on-chip data flash memory?
No, the R5F101GLANA#U0 does not include on-chip data flash memory. As indicated by the "101" in its part number (per Renesas' naming convention), it belongs to the data-flash-free variant of the RL78/G13 family. Its 128 KB code flash is used exclusively for program storage, while non-volatile parameter retention must be implemented externally or via emulated EEPROM techniques in code flash.
What package type and pin pitch does the R5F101GLANA#U0 use?
The R5F101GLANA#U0 uses a 48-pin HWQFN package (7 mm × 7 mm) with 0.5 mm pin pitch and wettable flanks. This package is designated by the "NA" suffix and ordered in trays (#U0). Its exposed thermal pad enhances heat dissipation in compact industrial enclosures, and the fine-pitch design supports high-density PCB layouts typical in modern sensor modules.
What is the operating temperature range specified for the R5F101GLANA#U0?
The R5F101GLANA#U0 is rated for operation from -40°C to +105°C, denoted by the "G" suffix in its part number. This industrial-grade temperature qualification makes it suitable for under-hood automotive applications, factory-floor controllers, and outdoor environmental monitoring systems where ambient extremes demand guaranteed functionality without derating.
Which serial communication interfaces are supported by the R5F101GLANA#U0?
The R5F101GLANA#U0 supports three serial interface types: CSI (SPI-compatible, up to 8 channels), UART/LIN (up to 4 channels with hardware LIN support), and I²C/Simplified I²C (up to 10 channels). All are multiplexed onto GPIO pins and configurable via dedicated SFRs - enabling flexible peripheral routing without requiring external level shifters or protocol translators.
