Product details
Overview
R5F100EHANA#20 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 at 32 MHz (41 DMIPS), supporting ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and multiple serial interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100EHANA#20 datasheet, R5F100EHANA#20 pinout, R5F100EHANA#20 application, or R5F100EHANA#20 equivalent, key selection criteria include its 40-pin HWQFN-0.5mm package, integrated RTC with calendar/alarm, background data flash rewrite capability, and support for LIN-compliant UART in low-voltage (1.6–5.5 V) operation.
Technical Context
The R5F100EHANA#20 implements the RL78 CPU core with 3-stage pipeline, configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz), and 1 MB address space. It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog/RTC.
Peripherals include eight 16-bit timers, one 12-bit interval timer, one real-time clock with calendar and clock correction, two to four UART/LIN channels, three to ten I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) channels - all accessible via 34 programmable I/O pins including 5 N-ch open-drain ports.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100EGANA#20 | Same 40-pin HWQFN package, but 48 KB flash / 4 KB data flash / 3 KB RAM; lower memory density | Suitable for simpler control tasks without extensive firmware or data logging | Select when firmware footprint < 48 KB and data logging requirements are minimal |
| R5F101EHANA#20 | Identical package and pinout, but no data flash memory (0 KB); retains 64 KB code flash and 4 KB RAM | Used where EEPROM-like nonvolatile storage is handled externally or not required | Choose when external SPI Flash or FRAM handles parameter storage, reducing cost and simplifying qualification |
Compared with R5F100EGANA#20 and R5F101EHANA#20, the R5F100EHANA#20 uniquely balances on-chip data persistence (4 KB data flash), computational headroom (41 DMIPS), and ultra-low-power operation - making it optimal for autonomous edge nodes requiring local data buffering and firmware resilience.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100EHANA#20?
The R5F100EHANA#20 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this via a 3-stage pipeline and supports dynamic clock scaling - including high-speed on-chip oscillator modes (±1.0% accuracy from 1–32 MHz) and ultra-low-speed 32.768 kHz subsystem clock for RTC and LVD operation. This enables deterministic real-time response while minimizing active power consumption.
Does the R5F100EHANA#20 support LIN bus communication, and how is it implemented?
Yes, the R5F100EHANA#20 supports LIN 2.2A-compliant communication through its UART peripherals. Each UART channel includes hardware-level sync-break detection, checksum generation (classic and enhanced), and automatic header/response timing - eliminating software overhead. The R5F100EHANA#20 can serve as either LIN master or slave, with configuration managed via dedicated control registers and interrupt-driven frame handling.
How does the data flash memory in the R5F100EHANA#20 differ from standard code flash, and what is its endurance?
The R5F100EHANA#20 includes 4 KB of dedicated data flash memory, separate from its 64 KB code flash. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash. Rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V, it is optimized for frequent parameter storage - such as calibration data, device configuration, or usage logs - without wearing out main program memory.
What low-power modes are available on the R5F100EHANA#20, and what is the lowest achievable current draw?
The R5F100EHANA#20 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA (typical) at VDD = 3.0 V and TA = 25°C. This mode retains RAM content and allows wake-up via RTC alarm, external interrupt, or LVD threshold crossing - enabling decade-long battery operation in intermittent-sensing applications like environmental monitors.
Is the R5F100EHANA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100EHANA#20 shares identical pinout and electrical characteristics with all other 40-pin HWQFN RL78/G13 devices (e.g., R5F100EGANA#20, R5F100EJANA#20). All share the same VDD/VSS distribution, I/O mapping, and peripheral pin assignments - enabling drop-in replacement within the same memory/feature tier, provided firmware accommodates differences in flash size or peripheral enablement.
