Product details
Overview
R5F1214AANA#40 from Renesas Electronics is a 16-pin HWQFN-packaged 16-bit RL78/G16 microcontroller with 16 KB code flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU), designed for ultra-low-power consumer electronics such as smart home controls and battery-powered human interface devices.
For engineers reviewing the R5F1214AANA#40 datasheet, R5F1214AANA#40 pinout, R5F1214AANA#40 application, or R5F1214AANA#40 equivalent, key selection criteria include its 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch) footprint, −40 to +85°C industrial-grade temperature range (A-suffix), 2.4–5.5 V single-supply operation, and support for STOP/HALT low-power modes with 61-μA/MHz active current.
Technical Context
The R5F1214AANA#40 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling configurable 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 12-bit interval timer, watchdog timer, and real-time clock with 99-year calendar and alarm functions.
Peripheral integration includes an 8/10-bit A/D converter with up to 11 analog inputs, two comparators with selectable reference sources, three serial interfaces (UART, simplified SPI/CSI, simplified I²C), and a dedicated capacitive touch sensing unit supporting both self- and mutual-capacitance configurations across 15 pins.

FAQ
What is the maximum operating frequency of the R5F1214AANA#40?
The R5F1214AANA#40 supports a maximum system clock frequency of 16 MHz using its high-speed on-chip oscillator. This yields a minimum instruction execution time of 0.0625 μs. The device also supports lower-frequency operation down to 32.768 kHz for ultra-low-power RTC and standby modes, with corresponding instruction times up to 30.5 μs.
Does the R5F1214AANA#40 support in-circuit debugging?
Yes, the R5F1214AANA#40 includes an on-chip debug function accessible via the TOOL0 (P40) and TOOLRxD/TOOLTxD (P01/P00) pins. It supports full breakpoint, step-through, and memory inspection capabilities without requiring external debug hardware beyond a standard E2 emulator or compatible JTAG/SWD adapter.
How many capacitive touch channels does the R5F1214AANA#40 support?
The R5F1214AANA#40 integrates a 15-channel capacitive touch sensing unit (CTSU). It supports self-capacitance mode (one key per pin, up to 15 keys) and mutual-capacitance matrix mode (transmit/receive pin pairing from the same 15 pins, supporting up to 16 keys), all implemented in hardware without CPU intervention during sensing.
What is the data flash endurance specification for the R5F1214AANA#40?
The R5F1214AANA#40 specifies 1,000,000 write/erase cycles (typical) for its 1 KB data flash memory. Each rewrite operates on 32-bit units, and background operation (BGO) is not supported-meaning code execution must be suspended from code flash during data flash writes.
Is an external crystal required for the R5F1214AANA#40 to operate?
No, the R5F1214AANA#40 can operate without an external crystal using its built-in high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy at TA = −20 to +85°C). External crystals (X1/X2) are optional and used only when higher timing precision or specific frequency requirements justify the added BOM cost and board space.
