Product details
Overview
R5F1217AMNA#40 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 capacitive touch sensing (15-channel CTSU), 10-bit A/D converter (11 channels), real-time clock with calendar, and low-power STOP/HALT modes - deployed in smart appliance control panels requiring robust HMI and thermal resilience.
For engineers reviewing the R5F1217AMNA#40 datasheet, R5F1217AMNA#40 pinout, R5F1217AMNA#40 application, or R5F1217AMNA#40 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.5-mm pitch) footprint, M-grade temperature rating (−40°C to +125°C), integrated CTSU for touch buttons, and dual serial interfaces (I²C + simplified SPI/CSI) supporting sensor fusion and display interface in space-constrained industrial controls.
Technical Context
The R5F1217AMNA#40 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting configurable instruction execution time 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 erase), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 2 KB SRAM.
Peripheral integration centers on human-machine interaction: 15-channel capacitive touch sensing unit (CTSU) supporting self- and mutual-capacitance configurations; 10-bit A/D converter with internal reference (0.815 V), temperature sensor, and touch voltage inputs; and dual serial interfaces - one full I²C channel plus up to three simplified SPI (CSI) or UART channels, all configurable via peripheral I/O redirection registers (PIOR).
