Overview
R5F1214CGNA#00 from Renesas Electronics is a 16-pin HWQFN-packaged 16-bit RL78/G16 microcontroller with 32 KB code flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU), designed for industrial control panels and low-power HMI applications operating from −40°C to +105°C.
For engineers reviewing the R5F1214CGNA#00 datasheet, R5F1214CGNA#00 pinout, R5F1214CGNA#00 application, or R5F1214CGNA#00 equivalent, key selection criteria include its 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch) footprint, 32 KB flash/2 KB RAM memory configuration, industrial-grade temperature range (−40°C to +105°C), and support for multiple serial interfaces including UART, simplified SPI (CSI), and I²C.
Technical Context
The R5F1214CGNA#00 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). It integrates a 12-bit interval timer, watchdog timer, and real-time clock with 99-year calendar and alarm functions.
Its analog subsystem includes an 8/10-bit A/D converter with up to 11 input channels, internal reference voltage (0.815 V TYP.), temperature sensor, and dual comparators with selectable high/low-speed modes and external/internal reference options - all supporting precise sensor interfacing in industrial environments.

FAQ
What is the maximum operating frequency of the R5F1214CGNA#00?
The R5F1214CGNA#00 supports a maximum system clock frequency of 16 MHz using its high-speed on-chip oscillator. This frequency is achievable with ±1.0% accuracy over the industrial temperature range (−20°C to +85°C) and VDD = 2.4–5.5 V. The device also supports lower-frequency operation down to 32.768 kHz for ultra-low-power RTC and sleep modes - all within the same R5F1214CGNA#00 silicon.
Does the R5F1214CGNA#00 support in-circuit debugging?
Yes, the R5F1214CGNA#00 includes an on-chip debug function accessible via dedicated TOOL0, TOOLRxD, and TOOLTxD pins. This allows full background debugging, flash programming, and real-time variable inspection without halting system operation - a capability confirmed in the R01DS0431EJ0130 datasheet for the R5F1214CGNA#00 variant.
What is the data flash endurance specification for the R5F1214CGNA#00?
The R5F1214CGNA#00 features 1 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 2.4–5.5 V. Unlike code flash, this memory supports 32-bit rewrite units and is intended for non-volatile parameter storage - a specification explicitly defined for the R5F1214CGNA#00 in the RL78/G16 datasheet Rev.1.30.
Can the R5F1214CGNA#00 operate at +105°C ambient temperature?
Yes, the R5F1214CGNA#00 is qualified for industrial applications (G-grade) with guaranteed operation from −40°C to +105°C ambient temperature. This rating is part of the device's ordering code definition ("G" suffix) and verified across all electrical parameters in the R01DS0431EJ0130 datasheet - confirming full functionality of its 32 KB flash, 2 KB RAM, CTSU, and analog peripherals at +105°C.
How many capacitive touch channels does the R5F1214CGNA#00 support?
The R5F1214CGNA#00 integrates a 15-channel Capacitive Touch Sensing Unit (CTSU) supporting both self-capacitance (up to 15 keys) and mutual-capacitance (up to 16 keys in matrix configuration). This capability is documented in the "Capacitive touch sensing unit (CTSUb)" section of the R01DS0431EJ0130 datasheet and applies specifically to the R5F1214CGNA#00 as a member of the RL78/G16 family with 16-pin HWQFN packaging.
