Product details
Overview
R5F1214AMNA#00 from Renesas Electronics is a 16-pin HWQFN-packaged RL78/G16 16-bit microcontroller with 16 KB flash, 2 KB RAM, and industrial-grade operation up to +125°C. It integrates capacitive touch sensing (15-channel CTSU), 8× 16-bit timers, 10-bit ADC (11-channel), RTC with calendar, and multiple serial interfaces including UART, simplified SPI (CSI), and I²C - deployed in smart appliance control panels requiring low-power, high-reliability HMI.
For engineers reviewing the R5F1214AMNA#00 datasheet, R5F1214AMNA#00 pinout, R5F1214AMNA#00 application, or R5F1214AMNA#00 equivalent, key selection criteria include its 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch) footprint, −40°C to +125°C operating range (M-grade), 16 KB code flash with 1 KB data flash, and integrated CTSU for touch-button interfaces without external components.
Technical Context
The R5F1214AMNA#00 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting variable instruction execution time from 0.0625 μs (@16 MHz) to 30.5 μs (@32.768 kHz). Its power management includes HALT and STOP modes, on-chip SPOR reset, and voltage monitoring across 2.4–5.5 V.
It features dual clock domains: a high-speed on-chip oscillator (selectable 1–16 MHz, ±1.5% accuracy at TA = −40 to +125°C) and a dedicated low-speed subsystem clock for RTC and watchdog. Peripheral integration includes 16 digital I/O pins (with N-ch open-drain capability), 10 interrupt channels, and hardware-accelerated BCD correction.

FAQ
What is the maximum operating temperature of the R5F1214AMNA#00?
The R5F1214AMNA#00 is rated for operation from −40°C to +125°C (M-grade industrial qualification), verified per Renesas' reliability testing standards. This makes it suitable for deployment in high-temperature environments such as inside sealed industrial enclosures or near heat-generating components. The device maintains full functionality and timing specifications across this entire range.
Does the R5F1214AMNA#00 support in-system programming via its debug interface?
Yes, the R5F1214AMNA#00 supports full in-system programming and debugging via its on-chip debug function using the TOOLRxD/TOOLTxD pins. No external programmer is required for firmware updates, and self-programming is enabled without boot swap functionality - allowing field upgrades while retaining existing application code integrity.
How many capacitive touch channels does the R5F1214AMNA#00 provide, and what configurations are supported?
The R5F1214AMNA#00 integrates 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). All channels operate without external RC components, and touch sensitivity is adjustable via firmware-controlled scan parameters.
What serial communication interfaces are available on the R5F1214AMNA#00?
The R5F1214AMNA#00 provides up to three UART channels, three simplified SPI (CSI) channels, three simplified I²C channels, and one standard I²C channel. These interfaces are multiplexed across GPIO pins and configurable via the Peripheral I/O Redirection Registers (PIOR), enabling flexible routing without PCB redesign.
Is an external crystal required for real-time clock operation on the R5F1214AMNA#00?
No - the R5F1214AMNA#00 includes a dedicated low-speed on-chip oscillator for RTC operation, supporting calendar functions and alarm interrupts without external components. However, for higher accuracy (e.g., <±20 ppm), an external 32.768 kHz crystal can be connected to X1/X2 pins and selected via system clock configuration.
