Product details
Overview
R5F1217AANA#00 from Renesas Electronics is a 24-pin HWQFN-packaged 16-bit RL78/G16 microcontroller with 16 KB code flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU), designed for ultra-low-power consumer electronics requiring robust HMI and mixed-signal control at −40°C to +85°C.
For engineers reviewing the R5F1217AANA#00 datasheet, R5F1217AANA#00 pinout, R5F1217AANA#00 application, or R5F1217AANA#00 equivalent, this page delivers verified electrical specifications, validated package mapping, confirmed peripheral integration (including RTC2, 16-bit timers ×8, 10-bit ADC ×11 ch), and real-world use-case context for rapid design-in decisions.
Technical Context
The R5F1217AANA#00 implements the RL78 CPU core with a 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). It integrates a dedicated low-speed on-chip oscillator for watchdog and RTC2 operation independent of main clock domain.
Its memory architecture separates 16 KB code flash (1 KB block erase) from 1 KB data flash (512 B blocks, 1M rewrite cycles), with background operation disabled during data flash writes-requiring careful sequencing in firmware. The CTSU supports both self- and mutual-capacitance modes across 15 pins without external components.
