Product details
Overview
R5F10EGEGNA#20 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G1A microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 28-channel 12-bit ADC, and ultra-low-power operation down to 0.57 µA in RTC+LVD halt mode. It integrates UART, I²C, SPI, RTC, programmable buzzer outputs, and operates from 1.6 V to 3.6 V - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F10EGEGNA#20 datasheet, R5F10EGEGNA#20 pinout, R5F10EGEGNA#20 application, or R5F10EGEGNA#20 equivalent, key selection criteria include its 48-pin HWQFN (7 × 7 mm) package, industrial-grade −40 °C to +105 °C ambient rating, 32 MHz max CPU frequency delivering 41 DMIPS, and support for background data flash operations with 1 million erase cycles.
Technical Context
The R5F10EGEGNA#20 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, enabling 86% of instructions in 1–2 clock cycles. Its CPU core supports 16×16 multiply-to-32-bit in one cycle and MAC in two cycles, paired with a 16-bit barrel shifter.
It features dual-clock domain operation: high-speed on-chip oscillator (32 MHz ±1% over voltage/temperature) and subsystem crystal oscillator (32.768 kHz), with independent power domains (VDD/EVDD0, VSS/EVSS0) for noise-sensitive analog and digital sections.

Does the R5F10EGEGNA#20 support functional safety standards like IEC 60730?
Yes, the R5F10EGEGNA#20 includes multiple hardware safety features required for IEC 60730 Class B compliance: flash memory CRC calculation engine, RAM parity error detection, SFR write protection, illegal memory access monitoring, clock frequency detection, and ADC self-test capability - all verified in Renesas' official safety manual for the RL78/G1A family.
What are the power consumption characteristics of the R5F10EGEGNA#20 in low-power modes?
The R5F10EGEGNA#20 achieves 0.57 µA in Halt mode with RTC and LVD active, 0.23 µA in Stop mode (RAM retained), and 0.7 mA in Snooze mode with UART active. Its 66 µA/MHz active-mode efficiency enables multi-year battery life in metering and sensor applications - values confirmed in the R01DS0151EJ0230 datasheet Section 1.1 under "Ultra-Low Power Technology".
How many analog input channels does the R5F10EGEGNA#20 support, and what is its ADC resolution?
The R5F10EGEGNA#20 integrates a 12-bit successive approximation register (SAR) ADC with up to 28 configurable analog input channels (ANI0–ANI30), 3.375 µs conversion time, and support for 1.6 V minimum supply. It includes internal voltage reference (1.45 V), AVREFP/AVREFM differential inputs, and an on-chip temperature sensor - all detailed in Section 1.1 "Rich Analog" of the R5F10EGEGNA#20 datasheet.
What package type and pin count does the R5F10EGEGNA#20 use, and is thermal pad connection required?
The R5F10EGEGNA#20 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with an exposed thermal pad. Renesas datasheet Section 1.3.3 explicitly recommends connecting the exposed die pad to VSS for optimal thermal performance and electrical stability - a requirement critical for sustained operation in industrial ambient temperatures up to +105 °C.
