Product details
Overview
R5F100EGANA#20 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 32 MHz max CPU speed (41 DMIPS), and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode). It integrates 12-bit ADC (12 channels), UART/SPI/I²C interfaces, RTC, watchdog timer, and DMA for embedded control in battery-powered industrial sensors and smart home nodes.
For engineers reviewing the R5F100EGANA#20 datasheet, R5F100EGANA#20 pinout, R5F100EGANA#20 application, or R5F100EGANA#20 equivalent, key selection criteria include its 40-pin HWQFN-0.5mm-pitch package, industrial-grade -40°C to +105°C operation (G-grade), integrated data flash with 1M rewrite cycles, and support for SNOOZE mode for low-latency peripheral wake-up without full CPU restart.
Technical Context
The R5F100EGANA#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 features dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for RTC/watchdog.
Its memory subsystem includes 64 KB code flash (1 KB block erase), 4 KB data flash with background operation (BGO), and 4 KB SRAM - enabling simultaneous program execution and nonvolatile data logging. Power management supports HALT, STOP, and SNOOZE modes with configurable wake sources including serial interface activity and ADC completion.

FAQ
What is the maximum operating frequency and performance of the R5F100EGANA#20?
The R5F100EGANA#20 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 μs in high-speed mode, and supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. This makes R5F100EGANA#20 suitable for both responsive control tasks and extended battery-life applications.
Does the R5F100EGANA#20 support in-system programming and secure firmware updates?
Yes, the R5F100EGANA#20 supports full in-system programming via its on-chip debug interface and boot swap functionality. It includes flash shield window protection and block-level erase/write prohibition to prevent unauthorized access or corruption. The 4 KB data flash supports background operation (BGO), allowing R5F100EGANA#20 to execute application code while logging parameters or updating configuration - critical for field-upgradable devices.
What analog peripherals are integrated into the R5F100EGANA#20?
The R5F100EGANA#20 integrates a 12-bit successive-approximation ADC with up to 12 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. These analog resources are accessible via dedicated ANI pins (e.g., P20/ANI0, P21/ANI1) and support differential measurements using AVREFP/AVREFM. No external reference or sensor is required for basic environmental monitoring, reducing system cost and calibration complexity in R5F100EGANA#20 designs.
How does the R5F100EGANA#20 achieve ultra-low-power operation in battery-powered applications?
The R5F100EGANA#20 achieves ultra-low-power operation through multiple hardware-optimized modes: STOP mode draws just 0.57 μA while maintaining RTC and LVD functionality, HALT mode consumes 0.23 μA, and SNOOZE mode enables fast peripheral wake without full CPU restart. Its 1.6–5.5 V wide supply range allows direct use of primary batteries or energy harvesters. These features make R5F100EGANA#20 ideal for multi-year deployments in wireless sensors and portable medical devices.
Is the R5F100EGANA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 40-pin HWQFN package - including R5F100EGANA#20, R5F100FGANA#20, and R5F100DGANA#20 - share identical pinouts and electrical characteristics. Memory size, data flash capacity, and RAM differ across variants, but PCB layout, decoupling, and peripheral routing remain fully reusable. This enables scalable design migration within the same footprint without redesigning R5F100EGANA#20-based hardware.
