Overview
R5F10EGDANA#20 from Renesas Electronics is a 48-pin HWQFN-packaged 16-bit RL78/G1A microcontroller with 48 KB flash, 4 KB data flash, and 2 KB RAM. It operates from 1.6 V to 3.6 V, delivers 41 DMIPS at 32 MHz, integrates a 12-bit 28-channel ADC (3.375 µs conversion), RTC with calendar/alarm, and ultra-low-power modes including 0.57 µA Halt (RTC + LVD) - deployed in battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F10EGDANA#20 datasheet, R5F10EGDANA#20 pinout, R5F10EGDANA#20 application, or R5F10EGDANA#20 equivalent, key selection criteria include its 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) package, industrial-grade −40 °C to +105 °C operation, dual I²C/SPI/UART interfaces, and hardware CRC for IEC 60730 compliance in safety-critical embedded control.
Technical Context
The R5F10EGDANA#20 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, enabling 86% of instructions in 1–2 clock cycles. Its on-chip high-speed oscillator achieves ±1% accuracy from 1.8 V to 3.6 V and −20 °C to +85 °C, supporting pre-configured frequencies up to 32 MHz.
It features two independent serial array units: Unit 0 provides UART0/UART1/I²C00/CSI00; Unit 1 adds UART2/LINSEL/I²C20/CSI20. The 8-channel timer array includes TI03/TO03 on P31 and RTC1HZ output on P30, with programmable buzzer outputs PCLBUZ0/PCLBUZ1.

Its RL78 16-bit CPU core executes 86% of instructions in just 1–2 clock cycles due to its 3-stage pipeline and CISC Harvard architecture - making R5F10EGDANA#20 suitable for real-time control loops with tight timing constraints.
Does the R5F10EGDANA#20 support IEC 60730 functional safety requirements?
Yes, the R5F10EGDANA#20 includes hardware-level safety features required for Class B compliance: flash memory CRC calculation, RAM parity error detection, SFR write protection, illegal memory access detection, clock stop/frequency monitoring, and ADC self-test - all documented in the R5F10EGDANA#20 datasheet for integration into certified firmware designs.
What package type and pin count does the R5F10EGDANA#20 use?
The R5F10EGDANA#20 uses a 48-pin HWQFN package measuring 7 × 7 mm with 0.5 mm pitch and an exposed die pad. This matches the pinout defined in Section 1.3.3 of the RL78/G1A datasheet (R01DS0151EJ0230), and the exposed pad must be connected to VSS for thermal and electrical stability - confirming R5F10EGDANA#20's suitability for compact, thermally constrained industrial PCBs.
How much ADC channel count and resolution does the R5F10EGDANA#20 provide?
The R5F10EGDANA#20 integrates a 12-bit successive-approximation ADC with up to 28 input channels (ANI0–ANI30, excluding gaps), achieving 3.375 µs conversion time. It supports 1.6 V minimum supply and includes internal voltage reference (1.45 V) and on-chip temperature sensor - enabling direct R5F10EGDANA#20 use in multi-sensor data acquisition without external reference or signal conditioning.
What low-power modes are available on the R5F10EGDANA#20 and their typical current draw?
The R5F10EGDANA#20 offers multiple low-power states: Stop mode draws 0.23 µA (RAM retained), Halt mode consumes 0.57 µA with RTC + LVD active, Snooze mode uses 0.6 mA during ADC conversion or 0.7 mA for UART receive, and active operation draws 66 µA per MHz - allowing R5F10EGDANA#20 to sustain decade-long operation in battery-powered edge devices.
