Product details
Overview
R5F1017DANA#20 from Renesas is a 24-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 48 KB flash, 4 KB data flash, and 2 KB RAM, operating from 1.6–5.5 V at -40°C to +85°C (industrial grade), delivering 41 DMIPS at 32 MHz for low-power sensor nodes and industrial control interfaces.
For engineers reviewing the R5F1017DANA#20 datasheet, R5F1017DANA#20 pinout, R5F1017DANA#20 application, or R5F1017DANA#20 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.5-mm pitch) footprint, absence of on-chip data flash programming capability, ultra-low power STOP mode (0.57 μA), and integrated 10-bit ADC with 12-channel analog input support.
Technical Context
The R5F1017DANA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It supports multiple low-power modes-HALT, STOP, and SNOOZE-with dedicated LVD and POR circuits for robust operation in fluctuating supply environments.
It integrates 8-channel 16-bit timers, one real-time clock with calendar/alarm functions, two UART/LIN channels, three I²C/Simplified I²C channels, and a 10-bit A/D converter with internal 1.45-V reference and temperature sensor-enabling self-contained measurement and communication in compact embedded systems.

FAQ
What is the flash memory configuration of the R5F1017DANA#20?
The R5F1017DANA#20 contains 48 KB of on-chip code flash memory and 4 KB of data flash memory. Unlike variants with "100" in the part number, this "101" suffix indicates that the data flash is present but not usable for self-programming - it is reserved for factory programming or read-only use in final applications. The code flash supports block erase (1 KB) and secure write protection.
Does the R5F1017DANA#20 support hardware debugging?
Yes, the R5F1017DANA#20 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. Debug access uses the dedicated TOOLRxD/TOOLTxD pins (P11/P12), supporting full breakpoint, watchpoint, and memory inspection capabilities without requiring additional debug headers or SWD/JTAG adapters.
What low-power modes are available on the R5F1017DANA#20?
The R5F1017DANA#20 supports HALT, STOP, and SNOOZE modes. STOP mode draws just 0.57 μA (typical) with RTC and LVD active - ideal for long-duration sleep between sensor readings. HALT halts the CPU while preserving RAM and peripheral states; SNOOZE enables selective peripheral operation (e.g., UART receive) during low-power wait states.
Can the R5F1017DANA#20 operate without an external crystal?
Yes, the R5F1017DANA#20 features a high-accuracy on-chip oscillator (±1.0% over -20°C to +85°C) selectable from 1–32 MHz. This eliminates the need for external crystals in most applications, reducing BOM cost and PCB area - though external crystals remain supported for higher precision timing requirements.
How many analog input channels does the R5F1017DANA#20 support?
The R5F1017DANA#20 integrates a 10-bit A/D converter with up to 12 analog input channels. Pin assignments include P20/ANI0, P21/ANI1, P22/ANI2, and additional ANIx channels mapped to other GPIO pins depending on port configuration - all referenced to the internal 1.45 V bandgap or external AVREF pins.
