It operates from 2.4–5.5 V, supports ultra-low-power STOP/HALT modes, and delivers real-time control for embedded HMI and sensor interface applications in industrial equipment.
For engineers reviewing the R5F1214CGSP#10 datasheet, R5F1214CGSP#10 pinout, R5F1214CGSP#10 application, or R5F1214CGSP#10 equivalent, key selection criteria include its 16-pin LSSOP package, −40°C to +105°C operating range (G-grade), 16-bit timer array (8 channels), 10-bit A/D converter (up to 11 inputs), and hardware-based capacitive touch sensing unit-critical for robust front-panel interfaces in harsh environments.
Technical Context
The R5F1214CGSP#10 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 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 includes three serial interfaces (UART, simplified SPI/CSI, simplified I²C), one full I²C channel, 16-bit timer array (8 channels), RTC with 99-year calendar, watchdog timer, 10-bit A/D converter with internal reference (0.815 V), two comparators, and a dedicated capacitive touch sensing unit supporting self- and mutual-capacitance configurations across up to 16 keys.

Yes, the R5F1214CGSP#10 includes an on-chip debug function and supports self-programming of code flash memory without boot swap. It features a flash shield window function to prevent unauthorized read/write access to protected memory regions - enabling secure field firmware updates and IP protection in deployed R5F1214CGSP#10 devices.
How many analog input channels and touch sensing inputs does the R5F1214CGSP#10 provide?
The R5F1214CGSP#10 integrates a 10-bit A/D converter with up to 11 analog input channels (ANI0–ANI10) and a dedicated capacitive touch sensing unit (CTSU) with 15 channels. These can be configured in self-capacitance mode (15 independent keys) or mutual-capacitance matrix mode (up to 16 keys) - delivering flexible, noise-immune sensing capability within the R5F1214CGSP#10.
What serial communication interfaces are available on the R5F1214CGSP#10?
The R5F1214CGSP#10 provides three simplified SPI (CSI) channels, three UART channels, three simplified I²C channels, and one full I²C channel. All are configurable via peripheral I/O redirection registers (PIOR), allowing flexible pin assignment for mixed-interface systems - making the R5F1214CGSP#10 well-suited for connecting to displays, sensors, and industrial buses without external level shifters.
Is the R5F1214CGSP#10 pin-compatible with other RL78/G16 variants in the same package?
Yes, all RL78/G16 devices in the 16-pin LSSOP package (e.g., R5F1214AGSP#10, R5F1214CGSP#10, R5F1214MGSP#10) share identical pinouts and electrical characteristics. Only memory size (16 KB vs. 32 KB), temperature grade (A/G/M), and oscillator calibration differ - enabling drop-in upgrades or downgrades of the R5F1214CGSP#10 within the same PCB layout.
