Product details
Overview
R5F1214CANA#00 from Renesas Electronics is a 16-pin HWQFN-packaged 32 KB flash RL78/G16 16-bit microcontroller with 2 KB RAM, 15-channel capacitive touch sensing unit (CTSU), and integrated 8/10-bit ADC for industrial human-machine interface applications operating from 2.4 to 5.5 V.
For engineers reviewing the R5F1214CANA#00 datasheet, R5F1214CANA#00 pinout, R5F1214CANA#00 application, or R5F1214CANA#00 equivalent, key selection criteria include its 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch) footprint, −40°C to +125°C M-grade temperature rating, 32 KB code flash with 1 KB data flash, and CTSU support for up to 16 keys in mutual capacitance mode.
Technical Context
The R5F1214CANA#00 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting 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 real-time clock with 99-year calendar and alarm function, watchdog timer, and background operation–disabled data flash rewriting requiring CPU stall during write cycles.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one channel of I²C, up to three simplified SPI (CSI) channels, up to three UART channels, two comparator channels with selectable reference sources, and a dedicated capacitive touch sensing unit with self- and mutual-capacitance modes configurable via 15 pins.

FAQ
What is the maximum operating temperature specification for the R5F1214CANA#00?
The R5F1214CANA#00 is rated for operation from −40°C to +125°C (M-grade), making it suitable for under-hood automotive and high-temperature industrial environments where standard industrial-grade MCUs would require derating or forced cooling. This rating is confirmed in the Renesas RL78/G16 datasheet R01DS0431EJ0130 Rev.1.30.
Does the R5F1214CANA#00 support self-programming of its code flash memory?
Yes, the R5F1214CANA#00 supports self-programming of its 32 KB code flash memory without requiring boot swap functionality or flash shield window features. This enables field firmware updates and secure parameter storage directly from application code, as documented in the RL78/G16 datasheet Section 1.1 "Features".
How many capacitive touch channels does the R5F1214CANA#00 provide, and what configurations are supported?
The R5F1214CANA#00 integrates a 15-channel capacitive touch sensing unit (CTSU) supporting both self-capacitance (up to 15 independent keys) and mutual-capacitance (up to 16 keys in matrix configuration) modes. Pin assignments and configuration details are specified in Tables 1-3 and 1-5 of the RL78/G16 datasheet R01DS0431EJ0130.
What communication interfaces are available on the R5F1214CANA#00?
The R5F1214CANA#00 provides one I²C channel, up to three simplified SPI (CSI) channels, and up to three UART channels. These interfaces are multiplexed across GPIO pins including P00–P07 and P40–P41, with detailed mapping provided in Table 1-3 of the RL78/G16 datasheet R01DS0431EJ0130.
Is an external crystal required for real-time clock operation on the R5F1214CANA#00?
No, the R5F1214CANA#00 includes a dedicated real-time clock (RTC) with 99-year calendar, alarm, and clock correction functions that operate using the internal 32.768 kHz subsystem clock. An external 32.768 kHz crystal may be used via X1/XT1 (P121) for higher accuracy, but is not required for basic RTC functionality.
