Renesas R5F1214AGNA#60

Overview

R5F1214AGNA#60 from Renesas Electronics is a 16-pin HWQFN-packaged RL78/G16 16-bit microcontroller with 16 KB flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU), designed for low-power industrial control applications operating from −40°C to +105°C. It features an RL78 CPU core (3-stage pipeline), 8× 16-bit timers, 10-bit A/D converter (up to 11 channels), and multiple serial interfaces including UART, simplified SPI (CSI), and I²C.

For engineers reviewing the R5F1214AGNA#60 datasheet, R5F1214AGNA#60 pinout, R5F1214AGNA#60 application, or R5F1214AGNA#60 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch) footprint, on-chip RTC with calendar function, and hardware-accelerated touch sensing supporting self- and mutual-capacitance configurations.

Technical Context

The R5F1214AGNA#60 implements the RL78 CPU core with CISC architecture and configurable instruction timing (0.0625 μs min @ 16 MHz to 30.5 μs @ 32.768 kHz), enabling dynamic power/performance trade-offs. Its memory subsystem includes 16 KB code flash (1 KB block size), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 2 KB SRAM - all accessible under single 2.4–5.5 V supply.

Peripheral integration centers on real-time control and human-machine interface: dual comparators, 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, 99-year RTC with alarm/correction, and a dedicated capacitive touch sensing unit (CTSU) supporting up to 16 keys in mutual-capacitance matrix mode using 15 pins.

FAQ

What is the maximum operating frequency and corresponding instruction timing for the R5F1214AGNA#60?

The R5F1214AGNA#60 achieves a minimum instruction execution time of 0.0625 μs when operating at 16 MHz using the high-speed on-chip oscillator. This timing is confirmed in the RL78/G16 datasheet Rev.1.30, Section 1.1 Features, and applies directly to the R5F1214AGNA#60 under VDD = 2.4–5.5 V and TA = −20°C to +85°C conditions.

Does the R5F1214AGNA#60 support background data flash rewriting while executing code from main flash?

No, the R5F1214AGNA#60 does not support background operation (BGO) for data flash. As specified in the datasheet Section 1.1, instructions cannot be executed from code flash memory during data flash rewriting. The R5F1214AGNA#60 requires careful state management - halting code execution or using interrupt-driven safe zones - when updating its 1 KB data flash.

How many capacitive touch channels does the R5F1214AGNA#60 support, and what configuration options are available?

The R5F1214AGNA#60 integrates a 15-channel capacitive touch sensing unit (CTSU). It supports self-capacitance mode (15 independent keys, one per pin) and mutual-capacitance matrix mode (up to 16 keys using transmit/receive pin combinations selected from the 15 available pins), as documented in Section 1.1 Features of the RL78/G16 datasheet.

What is the qualified operating temperature range for the R5F1214AGNA#60, and how is it indicated in the part number?

The R5F1214AGNA#60 is qualified for −40°C to +105°C operation, denoted by the "G" in its part number (R5F1214AGNA#60), per Figure 1-1 and Table 1-1 of the RL78/G16 datasheet. This industrial-grade rating ensures reliable performance in demanding environments such as factory automation and HVAC systems.

Which serial communication interfaces are available on the R5F1214AGNA#60, and how many channels does each support?

The R5F1214AGNA#60 provides three serial interface types: UART (1–3 channels), simplified SPI (CSI, 1–3 channels), and I²C (1–3 channels plus one dedicated IICA channel). These are confirmed in Section 1.1 Features and Table 1-3 (Multiplexed Functions of 16-pin Products) of the RL78/G16 datasheet Rev.1.30.
