Product details
Overview
R5F1217AGNA#00 from Renesas Electronics is a 24-pin HWQFN-packaged RL78/G16 16-bit microcontroller with 32 KB code flash, 2 KB RAM, and industrial-grade operation up to +105°C. It integrates an 8/10-bit ADC (11-channel), capacitive touch sensing unit (15-channel self-capacitance), real-time clock with calendar, and low-power HALT/STOP modes - deployed in smart home control panels requiring integrated HMI and sensor interfacing.
For engineers reviewing the R5F1217AGNA#00 datasheet, R5F1217AGNA#00 pinout, R5F1217AGNA#00 application, or R5F1217AGNA#00 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.5-mm pitch) footprint, 32 KB flash with 1 KB data flash, CTSU support for touch buttons, and dual serial interfaces (I²C + simplified SPI/CSI) for peripheral expansion in space-constrained industrial controls.
Technical Context
The R5F1217AGNA#00 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, 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 subsystem 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 and alarm, two comparators, and a dedicated capacitive touch sensing unit (CTSU) supporting both self- and mutual-capacitance configurations across up to 15 pins - all operating within VDD = 2.4–5.5 V and TA = −40 to +105°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1217CGNA#00 | Same package and pinout; 32 KB flash but G-grade (−40°C to +105°C) vs. A-grade (−40°C to +85°C) - R5F1217AGNA#00 is G-grade per datasheet Table 1-1 | Identical functional scope; differs only in temperature qualification - R5F1217AGNA#00 is explicitly G-grade per ordering table | Select R5F1217AGNA#00 when industrial ambient operation up to +105°C is required; verify thermal derating in enclosure design |
| R5F1216AGSP#50 | 20-pin LSSOP package; 16 KB flash, same 2 KB RAM; lacks CTSU and one I²C channel; no RTC2 calendar function | Suitable for simpler control tasks without touch interface or long-term timekeeping; lower pin count reduces PCB routing complexity | Choose R5F1216AGSP#50 for cost-optimized non-touch applications where 16 KB flash suffices and LSSOP assembly is preferred |

FAQ
What is the maximum operating temperature specification for R5F1217AGNA#00?
R5F1217AGNA#00 is rated for industrial operation from −40°C to +105°C (G-grade), as confirmed in Table 1-1 of the R01DS0431EJ0130 datasheet. This rating applies across the full VDD range of 2.4–5.5 V and ensures reliable performance in factory automation and building control environments where ambient temperatures exceed consumer-grade limits.
Does R5F1217AGNA#00 support in-system programming without external hardware?
Yes, R5F1217AGNA#00 supports on-chip debug and self-programming of code flash memory without boot swap functionality. The device includes an integrated debug interface accessible via TOOL0/TOOLRxD/TOOLTxD pins, enabling firmware updates in the field using standard UART-based protocols - no external programmer is required for basic flash reprogramming.
How many capacitive touch channels does R5F1217AGNA#00 provide, and what configuration modes are supported?
R5F1217AGNA#00 integrates a dedicated capacitive touch sensing unit (CTSU) with 15 channels. It supports self-capacitance mode (one key per pin, up to 15 keys) and mutual capacitance mode (matrix configuration using transmit/receive pin selection from the same 15 pins, supporting up to 16 keys) - both modes operate without external components and include built-in noise suppression.
What serial communication interfaces are available on R5F1217AGNA#00, and how many can operate concurrently?
R5F1217AGNA#00 provides three simplified SPI (CSI) channels, three UART channels, three simplified I²C (SIIC) channels, and one full I²C (IICA) channel. All interfaces share multiplexed pins but can operate concurrently - for example, CSI0, UART0, and IICA0 may run simultaneously using distinct pin groups as defined in Table 1-5 of the datasheet.
Is the data flash memory in R5F1217AGNA#00 capable of background operation during code execution?
No, R5F1217AGNA#00 does not support background operation (BGO) for data flash writes. During data flash rewriting, instruction execution from code flash memory is halted - requiring careful scheduling of write operations outside real-time critical sections. The datasheet explicitly states "Background operation (BGO) is not supported" for data flash memory in this device.
