Overview
R5F100GHANA#U0 from Renesas is a 48-pin, 128 KB flash, 8 KB data flash, 12 KB RAM RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), 1.6–5.5 V supply, and integrated 32 MHz high-accuracy on-chip oscillator (±1.0 %). It targets battery-powered industrial sensors and smart metering interfaces requiring long runtime and robust peripheral integration.
For engineers reviewing the R5F100GHANA#U0 datasheet, R5F100GHANA#U0 pinout, R5F100GHANA#U0 application, or R5F100GHANA#U0 equivalent, key selection criteria include its HWQFN-48 package, industrial-grade −40°C to +105°C operation (G-grade), 16-bit ADC with 26-channel analog input, real-time clock with calendar/alarm, and hardware DMA supporting background data flash rewriting.
Technical Context
The R5F100GHANA#U0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling variable instruction execution time from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and supports HALT/STOP/SNOOZE low-power modes. Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO) and 1M rewrite cycles, and 12 KB on-chip RAM.
Peripheral integration includes up to 26-channel 8/10-bit ADC, 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN, 2× CSI (SPI-compatible), 12-bit interval timer, RTC with calendar and correction, watchdog timer, and 4-channel DMA - all operating across the full 1.6–5.5 V voltage range.

R5F100GHANA#U0 operates up to 32 MHz using its on-chip high-accuracy oscillator, configurable for ±1.0 % tolerance across 1.8–5.5 V and −20°C to +85°C. External crystals (e.g., 32.768 kHz for RTC or 1–20 MHz for main clock) are optional but not required - the internal oscillator eliminates BOM cost and layout complexity for most applications.
Does R5F100GHANA#U0 support in-system programming and secure firmware updates?
Yes, R5F100GHANA#U0 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features. Its self-programming capability enables secure firmware updates in the field, with boot swap functionality ensuring fail-safe recovery during upgrade sequences.
How many analog input channels does the ADC in R5F100GHANA#U0 support, and what reference options are available?
R5F100GHANA#U0 integrates an 8/10-bit ADC with up to 26 analog input channels. Reference voltage options include external AVREFP/AVREFM pins, internal 1.45 V reference (selectable in HS mode), or VDD - enabling flexible ratiometric or absolute measurements depending on sensor type and accuracy requirements.
What low-power modes are available on R5F100GHANA#U0, and what is the typical current draw in each?
R5F100GHANA#U0 offers HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, it maintains RTC calendar, alarm, and low-voltage detection while consuming less than 1 μA - ideal for battery-backed real-time logging and wake-on-event applications.
Is R5F100GHANA#U0 pin-compatible with other RL78/G13 variants in the same package?
R5F100GHANA#U0 is pin-compatible with all RL78/G13 devices in the 48-pin HWQFN package (e.g., R5F100FHANA#U0, R5F100JHANA#U0), sharing identical pin functions and electrical characteristics. Memory size and peripheral enablement differ by part number, but PCB layout remains unchanged across this package group.
