Product details
Overview
R5F100EEGNA#U0 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, 3 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for ultra-low-power industrial sensor nodes and battery-powered control systems operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100EEGNA#U0 datasheet, R5F100EEGNA#U0 pinout, R5F100EEGNA#U0 application, or R5F100EEGNA#U0 equivalent, key selection criteria include its 0.57 μA STOP mode current, 40-pin 6 × 6 mm HWQFN-40 package, integrated LIN-capable UART, and support for background data flash rewriting during program execution.
Technical Context
The R5F100EEGNA#U0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and features a 1 MB address space with four register banks. It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and dedicated low-speed oscillator for RTC operation.
Power management includes HALT, STOP, and SNOOZE modes; the STOP mode draws only 0.57 μA with RTC + LVD active. Peripheral integration includes up to 16× 16-bit timers, 3× I²C interfaces, 4× UART/LIN channels, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100EEGNA#U0?
The R5F100EEGNA#U0 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0%). At this frequency, typical active current is 66 μA/MHz, resulting in ~2.1 mA total at 32 MHz with full peripheral enable. In STOP mode with RTC and LVD active, it draws only 0.57 μA - verified per R01DS0131EJ0380 Rev.3.80 datasheet Section 1.1.
Does the R5F100EEGNA#U0 support hardware LIN bus communication?
Yes, the R5F100EEGNA#U0 supports LIN 2.2/SAE J2602 via its UART peripherals with built-in sync-break detection, checksum generation, and identifier filtering. This capability is confirmed in the "Serial interface" section of the RL78/G13 datasheet (R01DS0131EJ0380), and applies directly to the R5F100EEGNA#U0 variant.
What is the data flash endurance and voltage range for reprogramming the R5F100EEGNA#U0?
The R5F100EEGNA#U0 includes 4 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. Background operation allows concurrent code execution during rewrites - a feature explicitly documented for the R5F100xx series in Section 1.1 of R01DS0131EJ0380.
Can the R5F100EEGNA#U0 interface directly with 1.8 V logic without level shifters?
Yes, the R5F100EEGNA#U0 supports different-potential I/O operation: selected ports tolerate 1.8 V, 2.5 V, or 3 V logic levels while powered from a 1.6–5.5 V VDD rail. This is implemented via configurable input buffers and is confirmed in the "I/O port" subsection of the RL78/G13 datasheet (R01DS0131EJ0380 Page 1).
What debug and programming interfaces are supported by the R5F100EEGNA#U0?
The R5F100EEGNA#U0 supports on-chip debugging via the single-wire SWD interface using the TOOLRxD/TOOLTxD pins (P11/P12). It requires the Renesas E2 emulator or compatible debug probe. No JTAG support is provided - this is consistent across all RL78/G13 devices as specified in Section 1.1 "On-chip debug function" of R01DS0131EJ0380.
