Product details
Overview
R5F101GEANA#20 from Renesas is a 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), 10-bit ADC (26-channel), UART/SPI/I²C interfaces, and real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GEANA#20 datasheet, R5F101GEANA#20 pinout, R5F101GEANA#20 application, or R5F101GEANA#20 equivalent, key selection criteria include its HWQFN-24 package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade, and integrated low-voltage detection with 14-level programmable threshold.
Technical Context
The R5F101GEANA#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 12-bit interval timer, one real-time clock with calendar/alarm functions, and a watchdog timer powered by a dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 26 analog input channels for the 10-bit A/D converter, three serial interface types (CSI/SPI, UART/LIN, I²C), and DMA controller with 2 channels enabling 2-clock transfers between SFR and RAM - all optimized for deterministic real-time control in resource-constrained embedded systems.

The R5F101GEANA#20 integrates 64 KB of on-chip code flash memory with 1 KB block erase granularity. It does not include on-chip data flash memory - this distinguishes it from the R5F100x series (e.g., R5F100GEANA#20). The flash supports self-programming with boot swap and flash shield window functions, enabling secure firmware updates in the field.
Does the R5F101GEANA#20 support hardware debugging and programming?
Yes, the R5F101GEANA#20 includes an on-chip debug function accessible via the P11 pin (TOOLRxD) and dedicated debug interface pins. It supports full in-circuit debugging, flash programming, and breakpoint execution using Renesas E2 emulator or compatible tools - no external debug probe is required for basic development.
What is the operating temperature range specified for the R5F101GEANA#20?
The R5F101GEANA#20 is rated for industrial operation from -40°C to +85°C, indicated by the "D" suffix in its family designation per Renesas RL78/G13 documentation. This qualifies it for use in factory automation, building controls, and outdoor metering equipment where ambient conditions exceed commercial-grade limits.
Can the R5F101GEANA#20 operate from a single 1.8 V supply?
Yes, the R5F101GEANA#20 supports single-supply operation from 1.6 V to 5.5 V, making it fully compatible with 1.8 V systems. Its I/O ports support different-potential interfacing, allowing direct connection to 1.8 V, 2.5 V, or 3.3 V peripherals without level shifters - verified across all operating modes including HALT and STOP.
How many analog input channels does the R5F101GEANA#20 ADC support?
The R5F101GEANA#20 features a 10-bit successive-approximation A/D converter with up to 26 analog input channels (ANI0–ANI25), as confirmed in the RL78/G13 datasheet section 1.1. This includes dedicated pins like P20/ANI0 and P21/ANI1, plus multiplexed port pins - enabling simultaneous monitoring of multiple sensors in compact embedded designs.
