Overview
R5F101EAANA#40 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 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), optimized for ultra-low-power embedded control in industrial and consumer applications including sensor nodes and power management systems.
For engineers reviewing the R5F101EAANA#40 datasheet, R5F101EAANA#40 pinout, R5F101EAANA#40 application, or R5F101EAANA#40 equivalent, key selection criteria include its 64 KB code flash with self-programming, 10-bit 26-channel ADC, real-time clock with calendar function, low-power STOP/HALT modes (0.57 μA RTC+LVD), and hardware UART/SPI/I²C interfaces for peripheral integration.
Technical Context
The R5F101EAANA#40 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, 16-bit timer array (12 channels), and watchdog timer with dedicated low-speed oscillator.
Its memory subsystem includes 64 KB on-chip flash (1 KB block size, security-protected erase/write), 4 KB data flash with background operation (BGO) and 1M-cycle endurance, and 4 KB SRAM - all accessible under single-supply 1.6–5.5 V operation across –40°C to +85°C ambient range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100EAANA#40 | Includes 4 KB data flash (same as R5F101EAANA#40) but adds 8 KB RAM and 128 KB code flash; identical pinout and package | Higher memory headroom for complex protocol stacks (e.g., Modbus TCP, OTA update) and larger data buffers | Select when firmware growth or future feature expansion is anticipated; same PCB layout and toolchain compatibility |
| RL78/G14 R5F104BAANA#40 | Same 40-pin HWQFN package, 64 KB flash, but adds USB 2.0 FS host/device, higher ADC speed (1.2 μs), and 16 KB RAM | Required for USB-connected devices (e.g., diagnostic tools, HID peripherals); not suitable if USB is unnecessary | Choose only when native USB connectivity is mandatory; otherwise R5F101EAANA#40 offers lower cost and power |
Compared with R5F100EAANA#40, the R5F101EAANA#40 trades RAM and flash capacity for lower BOM cost and reduced static power, while the RL78/G14 alternative adds USB at the expense of higher active current and silicon complexity - making R5F101EAANA#40 optimal for cost- and power-constrained standalone control tasks.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101EAANA#40?
The R5F101EAANA#40 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs in this mode, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time. This flexibility allows designers to balance performance and power across application states.
Does the R5F101EAANA#40 include data flash memory, and what are its key characteristics?
Yes, the R5F101EAANA#40 includes 4 KB of on-chip data flash memory. It supports background operation (BGO), allowing program execution from main flash while rewriting data flash. Rated for 1,000,000 write cycles at VDD = 1.8–5.5 V, it is commonly used for storing calibration data, device configuration, or event logs - and is managed via Renesas' Flash Self-Programming Library.
What low-power modes does the R5F101EAANA#40 support, and what is the lowest achievable current consumption?
The R5F101EAANA#40 supports HALT, STOP, and SNOOZE modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it achieves 0.57 μA typical current consumption at VDD = 3.0 V and TA = 25°C. This enables multi-year battery operation in applications such as utility meters and wireless sensors where periodic wake-up is sufficient.
Is the R5F101EAANA#40 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F101EAANA#40 is fully pin-compatible with all other 40-pin HWQFN RL78/G13 devices (e.g., R5F100EAANA#40, R5F101FAANA#40), sharing identical pin count, pitch, thermal pad layout, and I/O mapping. This enables drop-in replacement within the same memory/performance tier and simplifies design reuse across product families.
What development tools and software support are available for the R5F101EAANA#40?
Renesas provides comprehensive support for the R5F101EAANA#40, including the CS+ IDE with compiler and debugger, e² studio with GCC-based toolchain, and the Renesas Flash Programmer for programming. Hardware tools include the E2 emulator Lite and E2 emulator, both supporting on-chip debug via FINE interface. Application notes and sample code for ADC, RTC, UART, and low-power modes are publicly available on the Renesas website.
