Product details
Overview
R5F1216CGSP#50 from Renesas Electronics is a 20-pin, 32 KB flash, 2 KB RAM RL78/G16 16-bit microcontroller with integrated capacitive touch sensing (15-channel CTSU), 10-bit A/D converter (11-channel), real-time clock (99-year calendar), and low-power operation down to 61 µA/MHz at 125°C. It targets industrial HMI, appliance control, and sensor interface applications requiring robust timing, analog acquisition, and touch input.
For engineers reviewing the R5F1216CGSP#50 datasheet, R5F1216CGSP#50 pinout, R5F1216CGSP#50 application, or R5F1216CGSP#50 equivalent, key selection considerations include its 20-pin LSSOP package, −40°C to +105°C industrial temperature grade (G), 32 KB code flash with 1 KB data flash, and support for UART/SPI/I²C interfaces alongside dedicated touch-sensing and RTC peripherals.
Technical Context
The R5F1216CGSP#50 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting configurable 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 12-bit interval timer, watchdog timer, and real-time clock 2 with alarm and correction functions.
Its peripheral set includes an 8/10-bit A/D converter with internal reference voltage (0.815 V) and temperature sensor, two comparator channels with selectable reference sources, and a capacitive touch sensing unit supporting both self- and mutual-capacitance configurations across up to 16 keys. Serial interfaces comprise up to three simplified SPI (CSI), three UART, three simplified I²C, and one full I²C channel.

FAQ
What is the maximum operating frequency and corresponding instruction execution time for the R5F1216CGSP#50?
The R5F1216CGSP#50 supports a high-speed on-chip oscillator up to 16 MHz, yielding a minimum instruction execution time of 0.0625 µs. This timing assumes operation with the high-speed on-chip oscillator enabled and applies across the full industrial temperature range (−40°C to +105°C).
Does the R5F1216CGSP#50 support background operation during data flash rewriting?
No, the R5F1216CGSP#50 does not support background operation (BGO) during data flash rewriting. While rewriting the 1 KB data flash memory, instruction execution from code flash is disabled. This requires careful firmware sequencing to avoid system lockup during reprogramming.
How many analog input channels and what resolution does the A/D converter in the R5F1216CGSP#50 provide?
The R5F1216CGSP#50 integrates an 8/10-bit resolution A/D converter with up to 11 analog input channels (ANI0–ANI10). The converter operates over the full supply range of 2.4 V to 5.5 V and includes selectable internal reference voltages (0.815 V typical) and a built-in temperature sensor.
What is the capacitive touch sensing capability of the R5F1216CGSP#50?
The R5F1216CGSP#50 features a 15-channel capacitive touch sensing unit (CTSU) supporting both self-capacitance (up to 15 independent keys) and mutual-capacitance (matrix configuration supporting up to 16 keys) modes. It includes hardware acceleration and noise immunity features tailored for industrial-grade touch interfaces.
Is the R5F1216CGSP#50 pin-compatible with other RL78/G16 variants in the same package?
Yes, all RL78/G16 devices sharing the 20-pin LSSOP package-including R5F1216AGSP#50, R5F1216CGSP#50, and R5F1216CMSP#50-are fully pin-compatible. They share identical pin functions, electrical characteristics, and mechanical footprint, enabling drop-in replacement based on temperature grade and memory requirements.
