Renesas R5F101GHANA#20

Overview

R5F101GHANA#20 from Renesas is a 48-pin, 128 KB flash, data-flash-free RL78/G13 16-bit microcontroller with HWQFN package (7 × 7 mm, 0.5-mm pitch), operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz and ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in battery-powered industrial sensor nodes and smart metering interfaces.

For engineers reviewing the R5F101GHANA#20 datasheet, R5F101GHANA#20 pinout, R5F101GHANA#20 application, or R5F101GHANA#20 equivalent, key selection considerations include its 48-pin HWQFN footprint, absence of on-chip data flash, -40°C to +105°C industrial temperature grade (G suffix), and integrated RTC/calendar, 10-bit ADC (26 channels), and multiple serial interfaces (CSI, UART/LIN, I²C).

Technical Context

The R5F101GHANA#20 implements the RL78 CPU core with 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). It integrates a 12-bit interval timer, real-time clock with calendar/alarm/correction, and watchdog timer with dedicated low-speed oscillator.

Its peripheral set includes up to 16× 16-bit timers, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, 2–8-channel CSI, 8/10-bit ADC with internal 1.45 V reference and temperature sensor, and DMA controller with 2/4 channels supporting 2-clock transfers between SFR and RAM.

FAQ

What is the flash memory configuration of the R5F101GHANA#20?

The R5F101GHANA#20 features 128 KB of on-chip code flash memory and no integrated data flash. This configuration eliminates data flash wear leveling and erase/write management overhead, making it ideal for applications where firmware updates are infrequent and parameter storage is handled externally or in RAM with backup power.

Does the R5F101GHANA#20 support real-time clock functionality?

Yes, the R5F101GHANA#20 includes a dedicated real-time clock (RTC) module with full calendar support (year/month/day/hour/minute/second), alarm interrupt, and clock correction capability. It operates independently in STOP mode with only 0.57 μA consumption, enabling accurate timekeeping during ultra-low-power sleep states.

What is the operating temperature range specified for the R5F101GHANA#20?

The R5F101GHANA#20 is rated for an operating ambient temperature range of -40°C to +105°C, indicated by the 'G' suffix in the part number. This industrial-grade qualification makes it suitable for under-hood automotive modules, motor drive controllers, and outdoor industrial equipment where thermal resilience is essential.

Which package type does the R5F101GHANA#20 use, and what are its key mechanical attributes?

The R5F101GHANA#20 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. It complies with JEDEC standards for moisture sensitivity level (MSL) 3 and is lead-free/RoHS compliant. The compact footprint supports high-density PCB layouts while providing efficient thermal dissipation for sustained 32 MHz operation.

How many analog input channels does the R5F101GHANA#20 support, and what is the ADC resolution?

The R5F101GHANA#20 integrates an 8/10-bit successive approximation register (SAR) ADC supporting up to 26 analog input channels. It includes an internal 1.45 V reference voltage and on-chip temperature sensor, enabling accurate voltage, current, and thermal measurements without external reference components.
