Renesas R5F1214AANA#60

Overview

R5F1214AANA#60 from Renesas Electronics is a 16-pin HWQFN-packaged RL78/G16 16-bit microcontroller with 16 KB code flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU), designed for ultra-low-power consumer applications operating from −40°C to +85°C. It features an RL78 CPU core (3-stage pipeline), 8×16-bit timers, 10-bit A/D converter (11-channel), real-time clock with calendar, and multiple serial interfaces including UART, simplified SPI (CSI), and I²C.

For engineers reviewing the R5F1214AANA#60 datasheet, R5F1214AANA#60 pinout, R5F1214AANA#60 application, or R5F1214AANA#60 equivalent, key selection considerations include its 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch) footprint, 16 KB flash/2 KB RAM memory configuration, −40°C to +85°C industrial-grade temperature range, and native support for capacitive touch UIs without external components.

Technical Context

The R5F1214AANA#60 implements the RL78 CPU core with CISC architecture and configurable instruction timing (0.0625 μs min @ 16 MHz high-speed oscillator or 30.5 μs @ 32.768 kHz subsystem clock). It integrates a dedicated low-speed on-chip oscillator for watchdog and RTC operation independent of main clock domain.

Its peripheral set includes a 12-bit interval timer, 1-channel watchdog timer, 99-year real-time clock with alarm and correction, 1–3 channels of simplified SPI (CSI), 1–3 UART channels, and 1 I²C channel - all accessible via multiplexed I/O pins configured through the Peripheral I/O Redirection Register (PIOR).

FAQ

What is the maximum operating frequency of the R5F1214AANA#60?

The R5F1214AANA#60 supports up to 16 MHz operation using its high-speed on-chip oscillator, delivering a minimum instruction execution time of 0.0625 μs. External crystal or clock sources can also drive the CPU, but the internal oscillator eliminates BOM cost and layout complexity for most consumer applications. The R5F1214AANA#60 maintains full functionality across its entire 2.4–5.5 V supply range at this frequency.

Does the R5F1214AANA#60 support in-system programming without external tools?

Yes, the R5F1214AANA#60 includes an on-chip debug interface that enables full in-system programming and debugging via a single-wire SWD connection - no external programmer or bootloader is required. Its self-programming flash allows firmware updates directly from application code, though background operation (BGO) is not supported during data flash writes. This capability is fully implemented in the R5F1214AANA#60 silicon.

How many capacitive touch channels does the R5F1214AANA#60 support, and what configurations are available?

The R5F1214AANA#60 integrates a 15-channel capacitive touch sensing unit (CTSU) supporting both self-capacitance (15 independent keys) and mutual capacitance (matrix configuration up to 16 keys) modes. All 15 channels map directly to dedicated I/O pins (e.g., TS00–TS07, TS13) without external components. The R5F1214AANA#60's CTSU is factory-calibrated and requires no external tuning capacitors or resistors.

What is the guaranteed data retention endurance for the data flash memory in the R5F1214AANA#60?

The data flash memory in the R5F1214AANA#60 is rated for 1,000,000 write/erase cycles (typical) at VDD = 2.4–5.5 V and operates across the full −40°C to +85°C temperature range. Each rewrite occurs in 32-bit units within 512-byte blocks, and the R5F1214AANA#60 includes hardware error detection to prevent corruption during power-loss events.

Is the R5F1214AANA#60 pin-compatible with other RL78/G16 variants in the same package?

Yes, all RL78/G16 16-pin HWQFN variants - including R5F1214AANA#60, R5F1214CANA#60, R5F1214AGNA#60, and R5F1214AMNA#60 - share identical pinouts, electrical characteristics, and peripheral mappings. Only flash size (16 KB vs. 32 KB) and temperature grade (A/G/M) differ; the R5F1214AANA#60 is fully interchangeable at the PCB level with other NA-suffixed 16-pin devices.
