Product details
Overview
R5F1217CMNA#00 from Renesas Electronics is a 24-pin, 32 KB flash, 2 KB RAM RL78/G16 microcontroller with capacitive touch sensing (15-channel CTSU), 10-bit A/D converter (11 channels), and industrial-grade operation up to +125°C. It integrates UART, simplified SPI (CSI), simplified I²C, and real-time clock with calendar function for embedded control in harsh environments.
For engineers reviewing the R5F1217CMNA#00 datasheet, R5F1217CMNA#00 pinout, R5F1217CMNA#00 application, or R5F1217CMNA#00 equivalent, key selection criteria include its HWQFN-24 package, 2.4–5.5 V supply range, 61 µA/MHz active current, 16 MHz on-chip oscillator accuracy (±1.5% at TA = −40 to +125°C), and integrated touch interface for space-constrained industrial HMI designs.
Technical Context
The R5F1217CMNA#00 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.0625 µs (16 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its memory subsystem includes 32 KB code flash (1 KB blocks), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 2 KB SRAM.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, watchdog timer, RTC2 with 99-year calendar and alarm, two comparators, and a dedicated capacitive touch sensing unit (CTSU) supporting both self- and mutual-capacitance configurations across 15 pins. Serial interfaces comprise up to three CSI channels, three UART channels, three simplified I²C channels, and one full I²C channel.
