Product details
Overview
R5F1214CGSP#50 from Renesas Electronics is a 16-pin, industrial-grade RL78/G16 16-bit 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 real-time clock, 16-bit timers (8 channels), 10-bit ADC (11-channel), and multiple serial interfaces including UART, simplified SPI (CSI), and I²C - deployed in smart appliance control panels requiring robust HMI and low-power operation.
For engineers reviewing the R5F1214CGSP#50 datasheet, R5F1214CGSP#50 pinout, R5F1214CGSP#50 application, or R5F1214CGSP#50 equivalent, this page provides verified technical context, package-validated pin functions, application-specific design value, and two confirmed alternative parts for industrial embedded systems where extended temperature range (−40°C to +105°C), touch interface reliability, and flash self-programming are critical selection criteria.
Technical Context
The R5F1214CGSP#50 implements the RL78 CPU core with a 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). It integrates a dedicated low-speed on-chip oscillator for watchdog and RTC operation independent of main clock domain.
Its peripheral set includes a 99-year calendar RTC with alarm and correction, 12-bit interval timer, 1–2 comparator channels with selectable internal/external reference, and hardware-accelerated capacitive touch sensing unit (CTSU) supporting both self-capacitance (15 keys) and mutual-capacitance (16-key matrix) configurations - all operating within the −40°C to +105°C industrial temperature grade.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R5F1214CGSP#50?
The R5F1214CGSP#50 supports a high-speed on-chip oscillator up to 16 MHz, delivering a minimum instruction execution time of 0.0625 μs. This timing is achievable with the high-speed on-chip oscillator enabled and no wait states inserted - verified in the R01DS0431EJ0130 datasheet Section 1.1. The core maintains full functionality across its entire 2.4–5.5 V supply range at this frequency.
Does the R5F1214CGSP#50 support background operation during data flash rewriting?
No, the R5F1214CGSP#50 does not support background operation (BGO) during data flash rewriting. As specified in the R01DS0431EJ0130 datasheet Section 1.1, instructions cannot be executed from code flash memory while data flash is being rewritten. Firmware must enter a safe state or use STOP mode during write cycles to ensure integrity.
What is the pin configuration and package type of the R5F1214CGSP#50?
The R5F1214CGSP#50 uses a 16-pin plastic SSOP package (4.4 × 5.0 mm, 0.65-mm pitch), as confirmed in Table 1-1 and Figure 1-1 of the R01DS0431EJ0130 datasheet. Its pinout includes dedicated touch sense terminals (e.g., P02/TSCAP), dual UART channels, and crystal oscillator inputs (P121/P122) - all validated for industrial temperature operation.
How many analog input channels and what resolution does the ADC in the R5F1214CGSP#50 provide?
The R5F1214CGSP#50 integrates an 8/10-bit resolution successive-approximation ADC with up to 11 analog input channels (ANI0–ANI10), as documented in Section 1.1 of the R01DS0431EJ0130 datasheet. Input voltage range is tied to VDD (2.4–5.5 V), and internal reference voltages (0.815 V TYP.) are available for precision measurement independent of supply variation.
Is the R5F1214CGSP#50 pin-compatible with other RL78/G16 family members in the same package?
Yes, the R5F1214CGSP#50 is pin-compatible with other 16-pin SSOP variants in the RL78/G16 family, including R5F1214AGSP#50 and R5F1214AMSP#50. All share identical pin assignments, electrical characteristics, and multiplexed peripheral functions - enabling hardware reuse across consumer, industrial, and extended-temperature versions of the same footprint.
