Overview
R5F101GHANA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and DMA - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GHANA#U0 datasheet, R5F101GHANA#U0 pinout, R5F101GHANA#U0 application, or R5F101GHANA#U0 equivalent, key selection criteria include its no-data-flash configuration, -40°C to +105°C industrial temperature grade (G-suffix), 48-pin 7×7 mm HWQFN package, and support for background data flash rewriting and real-time clock calendar functions.
Technical Context
The R5F101GHANA#U0 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). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash supporting background operation (BGO) and 1M write cycles, and 12 KB on-chip RAM.
Peripheral integration includes 16-bit timer arrays (16 channels), 12-bit interval timer, calendar-capable RTC with alarm and correction, watchdog timer, 10-bit A/D converter with 26 analog inputs and internal temperature sensor, and serial interfaces: up to 8 CSI channels, 4 UART/LIN channels, and 10 I²C/Simplified I²C channels - all configurable under single-supply 1.6–5.5 V operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GHANA#V0 | LQFP-48 package (7×7 mm, 0.5 mm pitch) instead of HWQFN; identical electrical specs and memory map | Better suited for prototyping and manual soldering; less optimal for high-density or thermally constrained layouts | Select #V0 for breadboarding or low-volume assembly where QFN reflow capability is limited |
| R5F100GHANA#U0 | Includes 8 KB data flash (R5F100x) vs. none (R5F101x); otherwise identical pinout, package, and peripherals | Required when field-upgradable parameter storage or firmware-over-the-air logging is needed | Choose R5F100GHANA#U0 if data flash persistence is mandatory; R5F101GHANA#U0 saves cost where only code flash is used |
Compared with R5F101GHANA#U0, the #V0 variant trades HWQFN thermal performance and density for LQFP manufacturability, while R5F100GHANA#U0 adds data flash functionality at higher unit cost - making R5F101GHANA#U0 optimal for cost-sensitive, thermally demanding, flash-static applications.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101GHANA#U0?
The R5F101GHANA#U0 operates at up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy), delivering 41 DMIPS. This performance level supports real-time control loops, sensor fusion, and protocol stack processing in resource-constrained edge devices without requiring external clock sources.
Does the R5F101GHANA#U0 include data flash memory?
No, the R5F101GHANA#U0 does not include data flash memory. The "101" in the part number explicitly denotes "data flash not provided", distinguishing it from "100" variants (e.g., R5F100GHANA#U0) which integrate 8 KB of data flash. Code flash remains 128 KB in both cases.
What package type and pin count does the R5F101GHANA#U0 use?
The R5F101GHANA#U0 uses a 48-pin HWQFN package measuring 7 mm × 7 mm with 0.5 mm pitch. The "#U0" suffix confirms tray packaging for automated surface-mount assembly, and the "G" in the part number indicates industrial temperature grade (-40°C to +105°C).
How does the R5F101GHANA#U0 support low-power design in battery applications?
The R5F101GHANA#U0 supports ultra-low-power design via multiple sleep modes: HALT (1.2 μA), STOP (0.57 μA with RTC + LVD), and SNOOZE. Its 66 μA/MHz active current, combined with RTC calendar and wake-on-peripheral-interrupt capability, enables multi-year operation on coin-cell batteries in wireless sensor endpoints.
Which serial communication interfaces are available on the R5F101GHANA#U0?
The R5F101GHANA#U0 integrates three serial interface types: up to 8 CSI (SPI-compatible) channels, up to 4 UART/LIN channels (with LIN bus support), and up to 10 I²C/Simplified I²C channels. All are multiplexed onto GPIO pins and configurable via register settings without external hardware changes.
