Product details
Overview
R5F1214CGSP#30 from Renesas Electronics is a 16-pin, 32 KB flash RL78/G16 16-bit microcontroller with industrial-grade temperature range (−40°C to +105°C), 2 KB RAM, integrated capacitive touch sensing unit (15 channels), and dual 8/10-bit A/D converters (up to 11 analog inputs). It operates from 2.4 V to 5.5 V and supports ultra-low-power STOP/HALT modes for battery-powered industrial control panels.
For engineers reviewing the R5F1214CGSP#30 datasheet, R5F1214CGSP#30 pinout, R5F1214CGSP#30 application, or R5F1214CGSP#30 equivalent, key selection criteria include its SSOP-16 package compatibility, on-chip RTC with calendar function, CTSU-based human-machine interface support, and verified UART/SPI/I²C peripheral concurrency in real-time sensor aggregation systems.
Technical Context
The R5F1214CGSP#30 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling instruction execution times adjustable 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 a 16-bit timer array (8 channels), 12-bit interval timer, watchdog timer, and real-time clock 2 with 99-year calendar, alarm, and clock correction-enabling time-stamped data logging without external components. The CTSU supports both self-capacitance (15 keys) and mutual capacitance (16-key matrix) configurations via dedicated TSCAP pins.

FAQ
What is the maximum operating frequency of the R5F1214CGSP#30?
The R5F1214CGSP#30 supports a maximum CPU operating frequency of 16 MHz using the high-speed on-chip oscillator. This yields a minimum instruction execution time of 0.0625 μs. External crystal oscillators up to 20 MHz are also supported via X1/X2 pins, but system clock derivation depends on internal PLL configuration and prescaler settings documented in the RL78/G16 User's Manual.
Does the R5F1214CGSP#30 support background data flash programming?
No, the R5F1214CGSP#30 does not support background operation (BGO) for data flash writes. During data flash rewriting, instruction execution from code flash memory is disabled. This requires careful state management in firmware-typically using STOP mode entry before write sequences to minimize system interruption while preserving RAM contents.
How many capacitive touch channels does the R5F1214CGSP#30 support?
The R5F1214CGSP#30 integrates a dedicated Capacitive Touch Sensing Unit (CTSU) supporting up to 15 self-capacitance channels or a 4×4 mutual-capacitance matrix (16 keys) using any 15 GPIO pins configured as TSCAP, TSxx, or TX/RX. Pin P02 is designated as the primary TSCAP pin, and all touch channels share the same hardware engine-enabling efficient scanning with minimal CPU overhead.
What is the purpose of the VCOUT0 and VCOUT1 pins on the R5F1214CGSP#30?
VCOUT0 and VCOUT1 are voltage comparator output terminals on the R5F1214CGSP#30. VCOUT0 is multiplexed on P125 and P02; VCOUT1 on P07. They provide open-drain digital outputs reflecting the result of internal analog comparisons-used for threshold detection (e.g., overvoltage protection or liquid level sensing) without requiring external op-amps or ADC sampling.
Can the R5F1214CGSP#30 operate from a 3.3 V supply while maintaining full peripheral functionality?
Yes, the R5F1214CGSP#30 operates fully across 2.4 V to 5.5 V, including standard 3.3 V systems. All peripherals-including the 16-bit timer array, UART, CSI, simplified I²C, CTSU, and 8/10-bit ADC-function correctly at 3.3 V. The high-speed on-chip oscillator maintains ±1.0% accuracy across this voltage range at industrial temperatures (−20°C to +85°C), ensuring reliable timing without external components.
