Product details
Overview
R5F101EGANA#20 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit 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 modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and integrated real-time clock - deployed in battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F101EGANA#20 datasheet, R5F101EGANA#20 pinout, R5F101EGANA#20 application, or R5F101EGANA#20 equivalent, key selection criteria include its no-data-flash configuration, 40-pin 6×6 mm HWQFN-0.5mm-pitch package, -40°C to +85°C industrial temperature grade (D), and support for SNOOZE mode DMA transfers during low-power operation.
Technical Context
The R5F101EGANA#20 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, plus dual UART/LIN, up to 10 I²C channels, and 16-bit timers including calendar-mode RTC.
Power management includes on-chip POR, 14-level LVD with interrupt/reset options, HALT/STOP/SNOOZE modes, and background data flash rewriting (BGO) with 1M write endurance. The device lacks on-chip data flash (denoted by "101" in part number), distinguishing it from "100" variants, and targets cost-sensitive, power-constrained embedded control where flash self-programming is not required.

FAQ
What is the flash memory configuration of the R5F101EGANA#20?
The R5F101EGANA#20 contains 64 KB of code flash memory and zero data flash memory - indicated by the "101" prefix in the part number per Renesas' naming convention. This configuration is intended for applications with fixed firmware and no requirement for runtime parameter storage. The device supports self-programming of code flash only, and uses 4 KB of on-chip RAM for data buffering and stack operations. All flash blocks are 1 KB in size with optional erase/write protection.
Does the R5F101EGANA#20 support hardware debugging?
Yes, the R5F101EGANA#20 includes full on-chip debug functionality compatible with Renesas E2 emulator and CS+ IDE. It supports breakpoints, watchpoints, real-time variable monitoring, and flash programming via the single-wire debug (SWD) interface using pins P11 (TOOLRxD) and P12 (TOOLTxD). No external debug probe is required for development, and debug features remain accessible even when code flash security is enabled.
What are the power supply requirements for R5F101EGANA#20?
The R5F101EGANA#20 operates from a single supply voltage of 1.6 V to 5.5 V, eliminating the need for multiple rails or LDOs in most designs. It integrates an on-chip power-on-reset (POR) circuit and 14-level voltage detector (LVD) with programmable reset or interrupt thresholds. The device draws just 66 μA per MHz in active mode and sustains RTC + LVD operation at 0.57 μA in STOP mode - enabling direct connection to primary batteries or energy-harvesting sources.
Can the R5F101EGANA#20 drive an LCD directly?
No, the R5F101EGANA#20 does not integrate an LCD segment driver. While it supports general-purpose I/O with software-controlled PWM and on-chip clock output for basic timing, dedicated LCD driving requires external bias generation or a companion driver IC. For LCD applications, Renesas recommends the RL78/L12 or RL78/F14 families, which include built-in LCD controllers. The R5F101EGANA#20 is optimized for LED indicators, buzzer control, and character displays via SPI/I²C interfaces instead.
What packaging and compliance specifications apply to R5F101EGANA#20?
The R5F101EGANA#20 is supplied in a 40-pin HWQFN package (6 × 6 mm, 0.5 mm pitch) with wettable flanks, rated MSL3, and compliant with JEDEC J-STD-020D. It meets RoHS Directive 2011/65/EU, REACH SVHC, and is halogen-free. The device is qualified for industrial temperature range (−40°C to +85°C) per AEC-Q100 Class 2 standards, and supports lead-free reflow per IPC/JEDEC J-STD-020.
