Product details
Overview
R5F100EHANA#40 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), and real-time clock with calendar support - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100EHANA#40 datasheet, R5F100EHANA#40 pinout, R5F100EHANA#40 application, or R5F100EHANA#40 equivalent, key selection criteria include its 40-pin HWQFN (6 × 6 mm, 0.5 mm pitch) footprint, 64 KB code flash with self-programming and flash shield window, 10-bit ADC with internal 1.45 V reference and temperature sensor, and support for LIN-bus UART and simplified SPI/CSI interfaces.
Technical Context
The R5F100EHANA#40 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). It integrates dual-clock domains: high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 8-channel 16-bit timers, 1-channel 12-bit interval timer, 1-channel real-time clock with calendar/alarm/correction, 2–4 channel DMA controller, and serial interfaces comprising 2–4 UART/LIN channels, 2–8 CSI/SPI channels, and 3–10 I²C/Simplified I²C channels - all configurable via register-based control without external clock dependencies.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100EHANA#40?
The R5F100EHANA#40 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over –20 to +85°C), delivering 41 DMIPS. Its minimum instruction execution time is 0.03125 μs in high-speed mode, and it supports dynamic clock switching down to 32.768 kHz for ultra-low-power RTC operation - making R5F100EHANA#40 suitable for both responsive control and extended battery life.
Does the R5F100EHANA#40 support in-system programming and secure firmware updates?
Yes, the R5F100EHANA#40 supports full in-system programming via on-chip debug interface and includes boot swap functionality plus flash shield window protection. These features allow authenticated firmware updates without erasing critical parameters, and prevent unauthorized access to protected code regions - essential for field-deployed R5F100EHANA#40 implementations in certified metering or medical devices.
How many analog input channels does the R5F100EHANA#40 provide, and what ADC resolution is supported?
The R5F100EHANA#40 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), including dedicated AVREFP/AVREFM pins. It also provides an internal 1.45 V reference voltage and an integrated temperature sensor - both usable only in high-speed (HS) main mode. This ADC configuration enables precise sensor signal acquisition in R5F100EHANA#40-based environmental monitoring and motor control systems.
What low-power modes are available on the R5F100EHANA#40, and what is the lowest achievable current draw?
The R5F100EHANA#40 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across –40°C to +85°C. This enables decade-scale battery backup for real-time stamping and supervisory functions, a key advantage of the R5F100EHANA#40 in remote sensing and utility infrastructure applications.
Is the R5F100EHANA#40 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 40-pin HWQFN package - including R5F100EAANA#40 through R5F100EHANA#40 and R5F101x series - share identical pinouts and electrical characteristics. This allows hardware reuse across firmware variants, such as migrating from R5F100EHANA#40 to R5F100FHANA#40 for increased flash (96 KB) without PCB redesign - a validated design flexibility path for R5F100EHANA#40 users scaling feature sets.
