Product details
Overview
R5F101EDANA#U0 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 32 KB flash memory, 2 KB RAM, and no data flash. It operates from 1.6 V to 5.5 V, achieves 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode), targeting battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F101EDANA#U0 datasheet, R5F101EDANA#U0 pinout, R5F101EDANA#U0 application, or R5F101EDANA#U0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, absence of on-chip data flash, industrial-grade −40°C to +85°C temperature rating (D-suffix), and integrated 10-bit ADC with 26-channel analog input capability.
Technical Context
The R5F101EDANA#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 ultra-low-speed mode). Its memory map includes 1 MB address space and dedicated SFRs for peripheral control.
It integrates a 10-bit A/D converter with up to 26 analog inputs, real-time clock with calendar/alarm functions, 16-bit timers (up to 16 channels), UART/LIN, I²C, CSI, and DMA controller with 2 channels - all optimized for deterministic real-time control in resource-constrained embedded systems.

The R5F101EDANA#U0 is rated for industrial operation from −40°C to +85°C (D-suffix). This range is validated per Renesas specification R01DS0131EJ0380 and supports deployment in factory automation, outdoor metering, and HVAC equipment without derating.
Does the R5F101EDANA#U0 include an integrated data flash memory?
No, the R5F101EDANA#U0 does not include data flash memory. As indicated by the "101" in its part number (per Figure 1-1), it provides only code flash (32 KB) and SRAM (2 KB). For data logging or field-updatable parameters, external EEPROM or the R5F100EDANA#U0 variant must be used.
Which development tools support the R5F101EDANA#U0?
The R5F101EDANA#U0 is supported by Renesas E2 studio IDE, CS+ (formerly CubeSuite+), and the Renesas Starter Kit for RL78/G13 (RTK0EG0012D01000BJ). Debugging uses single-wire SWD via the TOOLRxD pin (P11), requiring no additional JTAG header.
Can the R5F101EDANA#U0 operate from a 1.8 V supply?
Yes, the R5F101EDANA#U0 supports 1.6 V to 5.5 V operation. At 1.8 V, it can run up to 16 MHz (per Section 1.1), enabling ultra-low-power operation in coin-cell or energy-harvesting systems while maintaining full peripheral functionality including ADC and RTC.
What is the maximum ADC resolution and channel count supported by the R5F101EDANA#U0?
The R5F101EDANA#U0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), including P20–P27 and P147. It supports internal 1.45 V reference and temperature sensor readout - all usable across the full 1.6–5.5 V supply range.
