Product details
Overview
R5F11AGHANB#20 from Renesas Electronics is a Bluetooth Low Energy 4.2 single-mode microcontroller integrating the 16-bit RL78-S2 CPU core and an on-chip 2.4 GHz RF transceiver. It delivers 192 KB flash, 20 KB RAM, 8 KB data flash, and operates from 1.6 V to 3.6 V across –40°C to +85°C. Its ultra-low-power RF sleep mode draws just 0.3 μA (TYP.), making it ideal for battery-powered wearable sensors and BLE beacons.
For engineers reviewing the R5F11AGHANB#20 datasheet, R5F11AGHANB#20 pinout, R5F11AGHANB#20 application, or R5F11AGHANB#20 equivalent, key selection considerations include its integrated AES-encrypted RF transceiver, 48-pin HWQFN package with dedicated RF GPIOs, RTC calendar support, and compliance with IEC60730/IEC61508 functional safety standards.
Technical Context
The R5F11AGHANB#20 implements a Harvard-architecture RL78-S2 CPU with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz). Its RF subsystem uses GFSK modulation in the 2.4 GHz ISM band with TDMA/TDD frequency hopping and built-in AES encryption - exclusively configured for slave operation with adaptivity.
Power management includes multiple low-power modes: MCU STOP (3.5 mA RF receive active), SNOOZE, and RF POWER_DOWN (0.3 μA TYP.). The device integrates dual clock domains - main system clock (up to 32 MHz) and RF slow clock (32.768 kHz) - with independent voltage regulators (VDD_RF, AVDD_RF, VSS_RF) and dedicated analog ground (AVSS_RF).

Equivalent & Alternatives
The following parts are listed as comparable options for similar BLE microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| nRF52833 DK | ARM Cortex-M4F core, 512 KB flash, 128 KB RAM, Bluetooth 5.1, no integrated USB or high-accuracy RTC | Higher compute throughput but requires external RTC and power management ICs for long-life battery use | Prefer when advanced DSP or Bluetooth Mesh stack complexity exceeds RL78 capabilities |
| CC2642R1F | ARM Cortex-M4F, 352 KB flash, 80 KB RAM, Bluetooth 5.1, integrated DC-DC, no on-chip flash shield or IEC60730 certification | Superior RF sensitivity and lower active current, but lacks functional safety qualification and secure boot features | Choose for maximum RF range and lowest active power where safety certification is not mandated |
Compared with nRF52833 DK and CC2642R1F, the R5F11AGHANB#20 trades raw performance for deterministic low-power behavior, integrated safety compliance, and reduced external component count - delivering faster time-to-certification and smaller footprint in cost-sensitive, battery-constrained BLE endpoints.

FAQ
What Bluetooth specification does the R5F11AGHANB#20 support?
The R5F11AGHANB#20 supports Bluetooth version 4.2 Low Energy Single Mode only. It implements GFSK modulation in the 2.4 GHz ISM band with TDMA/TDD frequency hopping and includes an on-chip AES encryption circuit. Operation is restricted to slave mode with adaptivity - it cannot function as a master or support Bluetooth Classic or BR/EDR profiles.
Does the R5F11AGHANB#20 require external RF components?
Yes, the R5F11AGHANB#20 requires external RF components including a 32 MHz crystal (XTAL1_RF/XTAL2_RF), matching network between ANT and antenna, and a 0.47–1 μF capacitor on REGC tied to VSS. While the RF transceiver is fully integrated, the ANT pin is single-ended and mandates board-level RF layout best practices for impedance control and isolation.
What is the maximum operating temperature range for the R5F11AGHANB#20?
The R5F11AGHANB#20 is rated for operation from –40°C to +85°C ambient temperature. This rating applies to both normal operation and flash memory programming modes. The "A" suffix in the part number (R5F11AGHANB#20) explicitly denotes consumer-grade temperature range compliance per Renesas' ordering code definition.
How much user-accessible flash and RAM does the R5F11AGHANB#20 provide?
The R5F11AGHANB#20 provides 192 KB of code flash memory, 20 KB of RAM, and 8 KB of data flash memory. The data flash supports background operation and 1 million erase cycles. When self-programming is enabled, usable RAM reduces to approximately 19 KB due to reserved system overhead - as documented in the RL78/G1D datasheet section 1.6.
Is the R5F11AGHANB#20 certified for functional safety standards?
Yes, the R5F11AGHANB#20 complies with IEC60730 Class B (for household appliances) and IEC61508 SIL2 (for industrial systems) functional safety standards. These certifications cover the MCU's built-in diagnostic features - including CRC calculation unit, RAM parity checking, illegal instruction detection, and watchdog timer with window function - enabling use in safety-critical BLE endpoints.
