Product details
Overview
R5F1217AMNA#00 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 self-capacitance), real-time clock with calendar, and dual serial interfaces including I²C and simplified SPI/CSI - deployed in smart appliance control panels requiring low-power, touch-enabled HMI.
For engineers reviewing the R5F1217AMNA#00 datasheet, R5F1217AMNA#00 pinout, R5F1217AMNA#00 application, or R5F1217AMNA#00 equivalent, this page delivers verified electrical specs, validated package mapping, confirmed peripheral functions, and real-world design context for embedded control and capacitive touch systems operating at extended temperature.
Technical Context
The R5F1217AMNA#00 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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 memory subsystem includes 32 KB code flash (1 KB block size), 1 KB data flash (512 B block), and 2 KB SRAM - all accessible under single 2.4–5.5 V supply.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, watchdog timer, RTC with 99-year calendar and alarm, and a dedicated capacitive touch sensing unit (CTSU) supporting both self- and mutual-capacitance configurations across up to 16 keys. Serial connectivity comprises up to three simplified SPI/CSI channels, three UART channels, three simplified I²C channels, and one full I²C interface.

FAQ
What is the maximum operating temperature specification for the R5F1217AMNA#00?
The R5F1217AMNA#00 is qualified for industrial applications with an operating ambient temperature range of −40°C to +125°C (M-grade). This rating is confirmed in the datasheet's "Operating ambient temperature" section and applies to all functional blocks including the CTSU, RTC, and flash memory - enabling deployment in high-thermal environments like motor drives or enclosed power supplies.
Does the R5F1217AMNA#00 include an integrated capacitive touch sensing unit?
Yes, the R5F1217AMNA#00 includes a dedicated Capacitive Touch Sensing Unit (CTSU) supporting up to 15 self-capacitance channels or 16 keys in mutual-capacitance matrix configuration. The CTSU is fully integrated into the silicon and requires no external components - its functionality is documented in Section 1.1 "Features" and Table 1-5 of the R01DS0431EJ0130 datasheet.
What package type and pin count does the R5F1217AMNA#00 use?
The R5F1217AMNA#00 uses a 24-pin HWQFN package (4.0 × 4.0 mm, 0.5 mm pitch) with exposed die pad, as specified in Figure 1-1 and Table 1-1 of the RL78/G16 datasheet. The "NA" suffix in the part number explicitly denotes the HWQFN package variant, and pin configuration details are provided in Section 1.3.4 and Table 1-5.
How much flash memory does the R5F1217AMNA#00 have, and what are its erase characteristics?
The R5F1217AMNA#00 contains 32 KB of code flash memory organized in 1 KB blocks, and 1 KB of data flash memory in 512 B blocks. Flash erase is block-based only - no partial-block or byte-level erase is supported - and write operations require prior full-block erase, as stated in the "Code flash memory" and "Data flash memory" subsections of Section 1.1.
Is the R5F1217AMNA#00 compatible with Renesas' standard debugging tools?
Yes, the R5F1217AMNA#00 supports on-chip debugging via the TOOL0/TOOLRxD/TOOLTxD pins (P40, P01, P00), which implement Renesas' standard E1/E20 debug interface protocol. These pins are documented in Tables 1-5 and 1-6, and full debug functionality - including flash programming and real-time trace - is enabled without external adapters when used with Renesas CS+ or e2 studio IDEs.
