Renesas R5F1217CANA#60

Overview

R5F1217CANA#60 from Renesas Electronics is a 24-pin HWQFN-packaged 32-bit RL78/G16 microcontroller with 32 KB code flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU), designed for low-power industrial human-machine interface applications operating from −40°C to +125°C.

For engineers reviewing the R5F1217CANA#60 datasheet, R5F1217CANA#60 pinout, R5F1217CANA#60 application, or R5F1217CANA#60 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.5-mm pitch) package, 32 KB flash/2 KB RAM memory configuration, 10-bit A/D converter with up to 11 channels, real-time clock with calendar function, and support for UART, simplified SPI (CSI), and simplified I²C interfaces.

Technical Context

The R5F1217CANA#60 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-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 16-bit timer array unit (8 channels), 12-bit interval timer, watchdog timer, and RTC2 with 99-year calendar and alarm functions.

Its analog subsystem includes an 8/10-bit A/D converter (VDD = 2.4–5.5 V, 4–11 input channels), two comparators with selectable reference sources, and a dedicated capacitive touch sensing unit (CTSU) supporting self-capacitance (15 keys) and mutual-capacitance (up to 16 keys in matrix) operation-all configurable via peripheral I/O redirection registers (PIOR).

FAQ

What is the maximum operating frequency and oscillator accuracy of the R5F1217CANA#60?

The R5F1217CANA#60 supports a high-speed on-chip oscillator up to 16 MHz with ±1.5% frequency accuracy over its full operating range of −40°C to +125°C. This eliminates the need for external crystals in many industrial applications while ensuring timing integrity for UART, timer, and touch sensing functions within the R5F1217CANA#60.

Does the R5F1217CANA#60 support in-system programming and secure firmware updates?

Yes, the R5F1217CANA#60 includes on-chip debug functionality and self-programming capability for code flash memory. It supports flash shield window protection to prevent unauthorized readout, enabling secure field firmware updates without requiring boot swap mechanisms-critical for maintaining integrity in deployed R5F1217CANA#60-based systems.

How many capacitive touch channels does the R5F1217CANA#60 support, and what configurations are available?

The R5F1217CANA#60 integrates a dedicated Capacitive Touch Sensing Unit (CTSU) supporting up to 15 self-capacitance channels (one pin per key) or up to 16 mutual-capacitance keys using matrix configuration across 15 pins. This flexibility allows designers to implement compact, robust touch interfaces directly within the R5F1217CANA#60 without external touch controllers.

What communication interfaces are available on the R5F1217CANA#60, and how are they allocated across pins?

The R5F1217CANA#60 provides up to three simplified SPI (CSI), three UART, three simplified I²C, and one full I²C interface. These are multiplexed across pins including P00/P01 (UART0), P60/P61 (I²C0), P40/P02 (CSI0), and remappable channels via PIOR registers-allowing dynamic allocation without hardware changes in the R5F1217CANA#60 design.

Is the R5F1217CANA#60 pin-compatible with other RL78/G16 variants in the same package?

Yes, all RL78/G16 devices in the 24-pin HWQFN package-including R5F1217CANA#60, R5F1217AMNA#60, and R5F1217CGNA#60-share identical pinouts and electrical characteristics. This enables drop-in replacement for memory or temperature grade upgrades while preserving PCB layout and firmware compatibility in the R5F1217CANA#60 footprint.
