Overview
R5F1214CMSP#50 from Renesas Electronics is a 16-pin, industrial-grade RL78/G16 microcontroller with 32 KB code flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU). It operates from 2.4–5.5 V, supports HALT/STOP low-power modes, and delivers ultra-low-speed timing at 32.768 kHz for battery-powered industrial control panels and sensor nodes.
For engineers reviewing the R5F1214CMSP#50 datasheet, R5F1214CMSP#50 pinout, R5F1214CMSP#50 application, or R5F1214CMSP#50 equivalent, this page provides verified electrical specifications, SSOP-16 package layout, real-time clock (RTC) calendar functionality, 16-bit timer array (8 channels), and confirmed alternative parts for design continuity in harsh-temperature embedded systems.
Technical Context
The R5F1214CMSP#50 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling 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 map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates dual flash resources: 32 KB code flash (1 KB block erase) and 1 KB data flash (512 B blocks, 1M rewrite cycles), both supporting self-programming without boot swap. The device includes a 99-year RTC with alarm and clock correction, plus an 8/10-bit A/D converter with internal reference (0.815 V) and temperature sensor.
