Renesas R5F1217AANA#60

Overview

R5F1217AANA#60 from Renesas Electronics is a 24-pin RL78/G16 16-bit microcontroller with 16 KB code flash, 2 KB RAM, and integrated capacitive touch sensing (15-channel CTSU), designed for low-power consumer applications operating from −40°C to +85°C. It features an RL78 CPU core (3-stage pipeline), 16-bit timer array (8 channels), 8/10-bit ADC (11 analog inputs), and dual serial interfaces including UART, simplified SPI (CSI), and I²C.

For engineers reviewing the R5F1217AANA#60 datasheet, R5F1217AANA#60 pinout, R5F1217AANA#60 application, or R5F1217AANA#60 equivalent, key selection criteria include its HWQFN-24 package (4 × 4 mm, 0.5-mm pitch), 2.4–5.5 V single-supply operation, STOP/HALT low-power modes, and on-chip RTC with calendar function - all critical for battery-powered HMI and sensor-edge devices.

Technical Context

The R5F1217AANA#60 implements the RL78 CPU core with configurable instruction timing (0.0625 μs min @ 16 MHz to 30.5 μs @ 32.768 kHz), 1 MB address space, and four register banks. Its memory subsystem includes 16 KB code flash (1 KB erase blocks) and 1 KB data flash (512 B blocks, 1M rewrite cycles), with background operation disabled during data flash writes.

Peripherals are tightly integrated: 16-bit timer array supports capture/compare/PWM across 8 channels; RTC2 provides 99-year calendar, alarm, and clock correction; CTSU enables self- and mutual-capacitance touch sensing up to 16 keys; and serial interfaces include up to 3 CSI, 3 UART, and 3 simplified I²C channels plus one full I²C master/slave interface.

FAQ

What is the maximum operating frequency and instruction timing of the R5F1217AANA#60?

The R5F1217AANA#60 supports a high-speed on-chip oscillator up to 16 MHz, delivering a minimum instruction execution time of 0.0625 μs. It also operates at ultra-low speed (32.768 kHz subsystem clock) with 30.5 μs per instruction - enabling dynamic power/performance scaling. The RL78 CPU core uses a 3-stage pipeline and supports configurable clock sources including external crystals (X1/X2) and internal oscillators.

Does the R5F1217AANA#60 support in-system programming and debug without external hardware?

Yes, the R5F1217AANA#60 includes an on-chip debug interface compatible with Renesas E2 emulator and supports self-programming of code and data flash memory without boot swap functionality. This allows firmware updates in the field using standard UART or CSI interfaces, and eliminates the need for external debug probes during development and production testing.

How many analog input channels and touch sensing channels does the R5F1217AANA#60 provide?

The R5F1217AANA#60 integrates an 8/10-bit A/D converter with up to 11 analog input channels (ANI0–ANI10) and a dedicated 15-channel capacitive touch sensing unit (CTSU). The CTSU supports both self-capacitance (15 independent keys) and mutual-capacitance (matrix configuration up to 16 keys), with built-in noise cancellation and automatic calibration routines.

What serial communication interfaces are available on the R5F1217AANA#60?

The R5F1217AANA#60 provides up to three simplified SPI (CSI) channels, three UART channels, three simplified I²C channels, and one full I²C master/slave interface. These are multiplexed across GPIO pins including P00–P07, P20–P23, and P40–P41, enabling concurrent communication with multiple sensors, displays, or wireless modules without external bus expanders.

Is the R5F1217AANA#60 pin-compatible with other RL78/G16 variants in HWQFN-24 package?

Yes, the R5F1217AANA#60 shares identical pinout, package dimensions (4.0 × 4.0 mm HWQFN), and electrical characteristics with other 24-pin RL78/G16 devices including R5F1217CGNA#60 and R5F1217CMNA#60. Pin compatibility extends to power, reset, debug, and peripheral signal assignments - allowing drop-in replacement for grade or memory upgrades without PCB redesign.
