Overview
R5F11AGGANB#20 from Renesas Electronics is a Bluetooth Low Energy 4.2 single-mode microcontroller integrating the 16-bit RL78-S2 CPU core, on-chip 2.4 GHz RF transceiver, 128 KB flash memory, 12 KB RAM, and 8 KB data flash. It operates from 1.6 V to 3.6 V across –40°C to +85°C and targets ultra-low-power wearable sensors and BLE peripheral devices.
For engineers reviewing the R5F11AGGANB#20 datasheet, R5F11AGGANB#20 pinout, R5F11AGGANB#20 application, or R5F11AGGANB#20 equivalent, key selection criteria include integrated BLE RF performance (4.3 mA TX / 3.5 mA RX), hardware AES encryption, 48-pin HWQFN package with RF-specific GPIOs, and compliance with IEC60730/IEC61508 functional safety standards.
Technical Context
The R5F11AGGANB#20 implements a dual-domain architecture: an RL78-S2 CPU core with Harvard CISC pipeline and a dedicated RF unit supporting GFSK modulation, TDMA/TDD frequency hopping, and slave-only adaptivity. Its RF block includes dedicated clock domains (32 MHz RF base clock, 32.768 kHz RF slow clock) and analog supply rails (AVDD_RF/VSS_RF).
Hardware peripherals include four DMA channels, eight 16-bit timer channels, RTC with full calendar/alarm, 8-channel 8/10-bit ADC with internal reference, and multiple serial interfaces (UART×2, CSI×2, simplified I²C×2, I²C×1). The RF interface uses single-ended ANT connection with GPIO-controlled PA/LNA enable via TXSELH_RF/TXSELL_RF pins.

FAQ
What Bluetooth specification does the R5F11AGGANB#20 support?
The R5F11AGGANB#20 supports Bluetooth version 4.2 Low Energy Single Mode only, operating exclusively as a slave device with adaptive frequency hopping and built-in AES encryption. It does not support Bluetooth Classic, dual-mode operation, or BLE 5.0 features such as extended advertising or higher throughput.
Does the R5F11AGGANB#20 require external RF components?
Yes, the R5F11AGGANB#20 requires external RF components including a 32 MHz crystal for the RF clock (XTAL1_RF/XTAL2_RF), matching network for the ANT pin, and optional external inductor/capacitor for the DC-DC converter (DCLIN/DCLOUT). The RF transceiver is integrated but not self-contained.
What is the maximum allowed supply voltage for the R5F11AGGANB#20 RF domain?
The absolute maximum supply voltage for the R5F11AGGANB#20 RF domain is +4.0 V on VDD_RF, AVDD_RF, and DCLIN pins. Operating voltage must remain within 1.6 V to 3.6 V for normal functionality, and DC-DC converter use prohibits LV mode operation below 1.8 V.
How many general-purpose I/O pins does the R5F11AGGANB#20 provide?
The R5F11AGGANB#20 provides 32 total I/O pins, including 20 CMOS I/O, 5 CMOS inputs, 1 CMOS output, 2 N-ch open-drain I/O (6 V tolerant), and 4 dedicated RF GPIOs (GPIO0–GPIO3). Pin functions are configurable via the Peripheral I/O Redirection Register (PIOR).
Is the R5F11AGGANB#20 qualified for functional safety standards?
Yes, the R5F11AGGANB#20 complies with IEC60730 Class B for household appliances and IEC61508 SIL2 for industrial systems. These certifications cover the MCU core, memory, clock monitoring, and watchdog timer - enabling use in safety-critical BLE endpoints without additional hardware redundancy.
