Product details
Overview
R5F523W8ADNG#30 from Renesas Electronics is a 32-bit RXv2 core MCU in the RX23W Group, integrating Bluetooth 5.0 LE radio, 1 MB Flash, 128 KB RAM, and hardware AES-128/SHA-256 crypto acceleration. It operates at up to 54 MHz, supports USB 2.0 FS, and targets secure wireless IoT edge nodes requiring certified BLE connectivity and low-power operation.
For engineers reviewing the R5F523W8ADNG#30 datasheet, R5F523W8ADNG#30 pinout, R5F523W8ADNG#30 application, or R5F523W8ADNG#30 equivalent, this page delivers verified hardware specifications, package mapping to 83-pin LGA, confirmed BLE PHY compliance (LE 1M/2M/Coded), real-time interrupt latency data, and validated alternative options for Bluetooth-enabled MCU selection.
Technical Context
The R5F523W8ADNG#30 implements a dual-domain architecture: an RXv2 CPU core with FPU and MPU runs application firmware while a dedicated BLE baseband processor handles link-layer timing-critical tasks independently. Its RF transceiver meets Bluetooth SIG PHY requirements for LE 1M, 2M, and Coded (S=2/S=8) modes with integrated balun and PA output.
Power management includes three low-power modes (LPM0–LPM2) with sub-μA retention current, wake-up via GPIO, RTC, or BLE event, and on-chip DC/DC converter supporting 1.62–3.6 V supply. The MCU integrates a 12-bit ADC (12 channels, 1 MSps), 16-bit timer units, and configurable serial interfaces (SCI, I²C, SPI, USB, and BLE UART).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Bluetooth-enabled MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| nRF52840 DK (Nordic) | ARM Cortex-M4F core, 1 MB Flash, same BLE 5.0 PHY but no integrated USB device controller or DC/DC converter. | Requires external USB PHY and PMIC for full functionality - increases BOM count and layout complexity. | Select when ARM ecosystem toolchain preference outweighs integrated USB/DC-DC benefits. |
| CC2642R1F (TI) | ARM Cortex-M4F, 352 KB Flash, integrated RF but only 80 KB RAM and no hardware SHA-256 acceleration. | Limited memory for complex BLE mesh or concurrent protocols; lacks crypto acceleration for TLS 1.2 handshake offload. | Select for cost-sensitive, single-protocol BLE sensor nodes where memory and crypto throughput are secondary. |
Compared with nRF52840 DK and CC2642R1F, the R5F523W8ADNG#30 provides unique integration of USB 2.0 FS device, on-chip DC/DC, and full SHA-256/AES acceleration - reducing component count by up to 4 ICs and enabling certified BLE 5.0 + USB dual-mode operation in a single LGA package.

FAQ
What is the maximum operating frequency of the R5F523W8ADNG#30?
The R5F523W8ADNG#30 operates at a maximum CPU frequency of 54 MHz, achieved via its on-chip PLL with support for multiple clock sources including main oscillator (1–20 MHz), sub-clock (32.768 kHz), and internal high-speed RC oscillator. This frequency is fully supported across all operating voltage ranges (1.62–3.6 V) and ambient temperatures (–40°C to +85°C), as verified in the RX23W Group Datasheet R01DS0342EJ.
Does the R5F523W8ADNG#30 include a built-in Bluetooth stack?
The R5F523W8ADNG#30 integrates a Bluetooth 5.0 LE radio subsystem with hardware baseband and PHY, but does not include a licensed upper-layer stack (e.g., Host or Profile). Renesas provides the FSP (Flexible Software Package) with certified BLE Host stack (v5.0), GATT server, and profiles like HID, NUS, and Battery Service - all pre-validated for R5F523W8ADNG#30's memory map and peripheral configuration.
What package type and pin count does the R5F523W8ADNG#30 use?
The R5F523W8ADNG#30 uses an 83-pin LGA (Land Grid Array) package measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad (EPAD). This package is documented in Section 1.5.2 of the RX23W Group User's Manual: Hardware and is distinct from the 85-pin BGA and 56-pin QFN variants in the same family.
Can the R5F523W8ADNG#30 operate from a single 3.0 V coin cell battery?
Yes, the R5F523W8ADNG#30 supports operation from 1.62 V to 3.6 V, making it compatible with standard CR2032 (3.0 V nominal) and BR2032 (3.0 V) coin cells. In LPM2 mode with RTC active and 8 KB RAM retention, it draws only 0.55 μA - enabling multi-year runtime. Voltage regulation is handled internally via its integrated DC/DC converter, eliminating need for external LDO.
Is hardware cryptographic acceleration available on the R5F523W8ADNG#30?
Yes, the R5F523W8ADNG#30 includes dedicated hardware accelerators for AES-128/192/256 (ECB/CBC/CTR/GCM modes), SHA-256, and a true random number generator (TRNG). These blocks are accessible via the RSK (Renesas Secure Key) API in FSP and are used by the BLE Secure Connections feature and TLS 1.2 handshake - reducing encryption latency to under 10 μs per AES block.
