Product details
Overview
R5F1217CANA#00 from Renesas Electronics is a 24-pin HWQFN-packaged 16-bit RL78/G16 microcontroller with 32 KB code flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU). It operates from 2.4–5.5 V, supports ultra-low-power STOP/HALT modes, and delivers real-time clock, 16-bit timers (8 channels), 10-bit ADC (11-channel), and dual SPI/I²C/UART interfaces - deployed in industrial human-machine interface modules requiring robust touch control and extended temperature operation.
For engineers reviewing the R5F1217CANA#00 datasheet, R5F1217CANA#00 pinout, R5F1217CANA#00 application, or R5F1217CANA#00 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.5-mm pitch) footprint, −40°C to +125°C M-grade industrial rating, 32 KB flash with 1 KB data flash, and hardware-accelerated capacitive touch sensing unit supporting self- and mutual-capacitance configurations.
Technical Context
The R5F1217CANA#00 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling configurable instruction execution time from 0.0625 μs (@16 MHz high-speed on-chip oscillator) to 30.5 μs (@32.768 kHz subsystem clock). Its memory subsystem includes 32 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-supply operation.
Peripheral integration centers on mixed-signal HMI support: a 10-bit ADC with internal reference (0.815 V) and temperature sensor, dual comparators with selectable reference sources, and a dedicated 15-channel capacitive touch sensing unit (CTSU) capable of up to 16-key mutual-capacitance matrix operation. Communication is handled by up to three simplified SPI (CSI), three UART, three simplified I²C, and one full I²C channel.

FAQ
What is the maximum operating temperature specification for the R5F1217CANA#00?
The R5F1217CANA#00 is rated for operation from −40°C to +125°C (M-grade industrial qualification), verified per Renesas' reliability testing standards. This allows deployment in high-ambient environments such as motor control enclosures, under-hood automotive modules, and factory-floor HMIs where thermal stress exceeds standard commercial or industrial grade limits. The R5F1217CANA#00 maintains full functionality including flash programming, ADC accuracy, and CTSU performance across this full range.
Does the R5F1217CANA#00 support background data flash rewriting while executing code from main flash?
No, the R5F1217CANA#00 does not support background operation (BGO) for data flash rewriting. During data flash write/erase operations, instruction execution from code flash memory is halted - meaning firmware must enter a safe state before initiating flash updates. This behavior is explicitly documented in the R5F1217CANA#00 datasheet section "Data flash memory" and applies uniformly across all RL78/G16 variants with 1 KB data flash.
How many capacitive touch channels does the R5F1217CANA#00 support, and what configuration modes are available?
The R5F1217CANA#00 integrates a dedicated Capacitive Touch Sensing Unit (CTSU) supporting up to 15 channels in self-capacitance mode (one key per pin) or up to 16 keys in mutual-capacitance matrix mode using transmit/receive pin combinations. Both modes operate independently of CPU load due to hardware acceleration, and the CTSU is fully compatible with Renesas' Smart Configurator and CTSU middleware. This capability is confirmed in the R5F1217CANA#00 datasheet section "Capacitive touch sensing unit (CTSUb)".
What oscillator options are available on the R5F1217CANA#00, and what is the accuracy over temperature?
The R5F1217CANA#00 features a high-speed on-chip oscillator selectable from 16/8/4/2/1 MHz with ±1.5% accuracy over −40°C to +125°C (M-grade), eliminating the need for external crystals in most timing-critical applications. It also includes a dedicated low-speed on-chip oscillator for watchdog and RTC operation. These specifications are guaranteed and tested per Renesas' R01DS0431EJ0130 datasheet Rev.1.30, page 1.
Is the R5F1217CANA#00 pin-compatible with other RL78/G16 variants in the 24-pin HWQFN package?
Yes, the R5F1217CANA#00 shares identical pinout, package dimensions (4.0 × 4.0 mm HWQFN, 0.5-mm pitch), and thermal pad layout with all other RL78/G16 24-pin HWQFN variants including R5F1217AGNA#00 and R5F1217AMNA#00. Pin function mapping is consistent across the family, enabling drop-in replacement between A/G/M grades when thermal and reliability requirements align - as confirmed in Table 1-5 of the R01DS0431EJ0130 datasheet.
