Product details
Overview
R5F1217AMNA#20 from Renesas Electronics is a 24-pin HWQFN-packaged 16-bit RL78/G16 microcontroller with 32 KB code flash, 2 KB RAM, and industrial-grade operation up to +125°C. It integrates an 8/10-bit ADC (11-channel), capacitive touch sensing unit (15-channel), real-time clock with calendar, and dual serial interfaces including I²C and simplified SPI/UART - deployed in smart appliance control panels requiring low-power HMI and sensor fusion.
For engineers reviewing the R5F1217AMNA#20 datasheet, R5F1217AMNA#20 pinout, R5F1217AMNA#20 application, or R5F1217AMNA#20 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.5-mm pitch) footprint, TA = −40 to +125°C rating, 32 KB flash/2 KB RAM memory configuration, and integrated CTSU for self- and mutual-capacitance touch sensing without external components.
Technical Context
The R5F1217AMNA#20 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.0625 μs (@16 MHz high-speed on-chip oscillator) to 30.5 μs (@32.768 kHz subsystem clock). Its power management includes HALT and STOP modes, selectable SPOR reset levels, and 61-μA/MHz operating current at 125°C.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, watchdog timer, RTC2 with 99-year calendar and alarm, and a dedicated capacitive touch sensing unit (CTSU) supporting up to 16 keys via mutual capacitance matrix or 15 keys via self-capacitance - all operating from a single 2.4–5.5 V supply without external reference components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1217CMNA#20 | Same package and peripherals but rated for −40°C to +105°C (G-grade); 32 KB flash/2 KB RAM identical. | Suitable for industrial equipment not requiring extended high-temp operation; lower cost where 125°C is unnecessary. | Select when ambient temperature stays ≤+105°C and cost optimization is prioritized over thermal margin. |
| R5F1214AMNA#20 | 16-pin HWQFN variant with 16 KB flash, 2 KB RAM, and reduced peripheral count (e.g., no RTC2, only 4 ADC channels). | Targeted at simpler HMI or sensor nodes where calendar/timekeeping and full ADC channel count are not required. | Choose for space-constrained, cost-sensitive designs with minimal feature set - avoids over-specifying flash and peripherals. |
