Product details
Overview
R5F101EFANA#U0 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 at 1.6–5.5 V and delivering 41 DMIPS at 32 MHz. It integrates a 10-bit ADC (26 channels), RTC, UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for battery-powered industrial sensing and control.
For engineers reviewing the R5F101EFANA#U0 datasheet, R5F101EFANA#U0 pinout, R5F101EFANA#U0 application, or R5F101EFANA#U0 equivalent, key selection criteria include its 40-pin HWQFN-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade, and support for background data flash rewriting via BGO.
Technical Context
The R5F101EFANA#U0 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). Its memory subsystem includes 64 KB code flash (1 KB block size), 4 KB RAM, and no integrated data flash-consistent with the R5F101x family designation.
Peripheral integration includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8× 16-bit timers, real-time clock with calendar/alarm, 2× UART/LIN, 2× CSI (SPI-compatible), 3× I²C, DMA controller (2 channels), and hardware multiplier/divider. Power management features HALT, STOP, and SNOOZE modes with on-chip POR and LVD.

FAQ
What is the flash memory configuration of the R5F101EFANA#U0?
The R5F101EFANA#U0 contains 64 KB of on-chip code flash memory organized in 1 KB erasable blocks, with no integrated data flash-consistent with the R5F101x family designation. It supports self-programming with boot swap functionality and flash shield window protection. The R5F101EFANA#U0 uses RAM starting at address FEF00H for flash library operations during rewriting.
Does the R5F101EFANA#U0 support real-time clock functionality?
Yes, the R5F101EFANA#U0 integrates a full-featured real-time clock (RTC) with calendar support for 99 years, alarm interrupt capability, and hardware clock correction. It operates independently in STOP mode with only 0.57 μA current draw when powered by VDD, enabling accurate timekeeping in battery-backed applications without external RTC ICs.
What package type and pin count does the R5F101EFANA#U0 use?
The R5F101EFANA#U0 is housed in a 40-pin HWQFN package (6 × 6 mm, 0.5 mm pitch), designated by the "NA" suffix and "#U0" tray packaging code. This RoHS-compliant, lead-free package supports automated assembly and provides thermal performance suitable for industrial ambient temperatures up to +85°C.
How does the R5F101EFANA#U0 differ from R5F100EFANA#U0?
The R5F101EFANA#U0 omits the 4 KB on-chip data flash present in the R5F100EFANA#U0, reducing cost and die area while retaining identical code flash (64 KB), RAM (4 KB), peripherals, and pinout. Both share the same 40-pin HWQFN package and operate across -40°C to +85°C, but R5F101EFANA#U0 targets applications where parameter storage is handled externally or via code flash emulation.
What low-power modes are available on the R5F101EFANA#U0?
The R5F101EFANA#U0 supports HALT, STOP, and SNOOZE modes. STOP mode draws just 0.57 μA while maintaining RTC and LVD operation; HALT mode consumes 66 μA/MHz; SNOOZE enables peripheral-triggered wake-up with minimal latency. These modes are controlled via dedicated system registers and require no external components to achieve certified ultra-low-power operation.
