Technical Context

The R5F1217CMNA#60 implements the RL78 CPU core 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). Its memory architecture includes 32 KB code flash (1 KB block size), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 2 KB SRAM.

Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, watchdog timer, RTC2 with 99-year calendar, two comparators, and a dedicated capacitive touch sensing unit (CTSU) supporting both self- and mutual-capacitance configurations across 15 pins. Serial connectivity comprises up to three simplified SPI/CSI channels, three UART channels, three simplified I²C channels, and one full I²C interface.

FAQ

What is the maximum operating frequency and corresponding instruction timing for the R5F1217CMNA#60?

The R5F1217CMNA#60 supports a maximum operating frequency of 16 MHz using its high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.0625 μs. This timing is achievable only when the high-speed oscillator is selected and configured per the device's clock control registers. The R5F1217CMNA#60 also supports slower clocks down to 32.768 kHz for ultra-low-power operation, extending instruction time to 30.5 μs.

Does the R5F1217CMNA#60 support background data flash rewriting while executing code from main flash?

No, the R5F1217CMNA#60 does not support background operation (BGO) for data flash rewriting. During data flash write or erase operations, instruction execution from code flash memory is halted. This means firmware must enter a safe state-disabling interrupts and halting real-time tasks-before initiating flash updates. The R5F1217CMNA#60 specifies that instructions cannot be executed from code flash while rewriting data flash, unlike some higher-tier RL78 variants with BGO capability.

How many capacitive touch channels does the R5F1217CMNA#60 support, and what configuration options are available?

The R5F1217CMNA#60 integrates a dedicated Capacitive Touch Sensing Unit (CTSU) supporting up to 15 channels. It enables both self-capacitance mode (one key per pin, up to 15 keys) and mutual-capacitance mode (matrix configuration using transmit/receive pin pairs from the same 15-pin pool, supporting up to 16 keys). All CTSU functionality is hardware-accelerated and operates independently of the CPU core, allowing touch scanning during low-power STOP mode with minimal current draw.

What are the supported serial communication interfaces on the R5F1217CMNA#60, and how are they mapped to pins?

The R5F1217CMNA#60 supports simplified SPI (CSI), UART, simplified I²C, and full I²C interfaces. Specifically, it offers up to three CSI channels, three UART channels, three simplified I²C channels, and one full I²C interface. These are multiplexed across pins such as P00 (SO00/TxD0/SCK11/SCL11/SCLA0), P01 (SI00/RxD0/SDA00/SI11/SDA11/SO11/SDAA0), and P02 (SCK00/SCL00/SCK20/SCL20). Pin function selection is controlled via the Peripheral I/O Redirection Registers (PIOR), enabling flexible routing without hardware changes.

Is the R5F1217CMNA#60 pin-compatible with other RL78/G16 devices in the same package variant?

Yes, the R5F1217CMNA#60 is pin-compatible with all other RL78/G16 devices in the 24-pin HWQFN package (e.g., R5F1217CGNA#60, R5F1217AMNA#60), sharing identical pin count, pitch, thermal pad layout, and base I/O mapping. Differences between variants-such as flash size (16 KB vs. 32 KB) or temperature grade (G vs. M)-do not affect pin assignment or electrical characteristics. This allows drop-in replacement during qualification or cost optimization without PCB redesign.
